What is clinodactyly?
Clinodactyly is the abnormal growth and development of the small bones of the finger. Instead of the bones being rectangular, they are wedge-shaped. It usually, but not always, describes the curving of the pinky toward the ring finger.
How common is clinodactyly?
Clinodactyly is thought to occur in about 10% of the population. It occurs with higher frequency in males and is considered to be a benign congenital defect. It has also been thought to be a symptom of children with mental retardation or Down syndrome, but on another site I read that it may be a predisposing factor for those with artistic, creative, or even musical tendencies.
How is clinodactyly treated?
Mild finger curvature rarely causes pain or functional problems. For this reason, surgery is not typically recommended.
How many of you have or know someone that has clinodactyly?
I have three step children, two of which have a curved pinky. I never even noticed it until I gave birth to my daughter and, as many new parents do, I studied every little thing on my newborn. I found the curved pinkies on both hands and I also saw she had curved toes. Her father has curved toes, so I understood that, and then I noticed that my two step children had the same curve in their pinkies, so I just figured it was yet another thing that tied my daughter to her father (my daughter could be her father's clone). Then one day I was doing some research on the web, and I found a name for what my daughter has. According to my research, they say the doctor will have to monitor the curvature and make sure it doesn't affect a child's physical abilities. Well, my doctor has seen my daughter for four months now, and not once has she mentioned anything about clinodactyly.
I created this article to discuss with other people:
- any relevant information regarding clinodactyly
- to find out if there is any truth to the theory that clinodactyly is linked to mental retardation or Down syndrome
- if it is linked to creativity, artistic abilities, or even musical talent.
So please, read and join the discussion in the comments section below.
Julie on October 03, 2020:
My father, myself and my daughter all have the curved pinkie finger on our left hand.
Yes we are all very artistic naturally without ever having taken art in school or college.
My father draws and can build things, I draw, sew, and anything creative I love. My daughter can draw and is an amazing painter.
Leigh on October 26, 2018:
Hi!! I have a crooked or curved pinky on my right hand and my aunt does too! I have to say that i do have artistic and music abilities and my aunt sings. I definantly dissagree that it has something to do with retardation and my aunt was literally valdictorian of her class. My daughter also has Clinodactyly and she is an art teacher and plays the piano and she also sings. most of my family are atrists and musically inclined. My youngest sister also has the crooked pinky so it definantly is hereditary. I was also wondering if Scottish people were more inclined to have this defect.
Jo on August 06, 2018:
Im curious if hereditary dna of us. If we're all linked by culture? I have both. my dad has 1. Nombre of my children do. Nor my siblings. My father is an identical mirror twin. His is on the right his brothers the left. We are a mixed culture according to dna
jordyn on January 16, 2018:
I have curved pinkies but not on my toes. I do have a learning disability and I don't know if it's the of the curve fingers or if it's from my family genes. it is hard sometimes to play instrument's. Although, its easy to do sports and other activity's. But as a girl when I find out that the doctor wanted to have surgery or cut them off, them my family chosen surgery. but it was hard growing when find out about it, then others will pick on because of it. Because of my fingers I learned who I am and what I can. when I was given the option of having another surgery I declined it because I excepted how my hand are. if you gave your child an option of having surgery or leaving how her or his hands are. I would choose to leave them how they are and proceed on doing thing that there good at.
Pinkie Pie on January 02, 2018:
I have inwardly curved pinkies and toes. I do not have any other disabilities. I have a high level of education and I have a love of music and play several instruments. I think you shouldn't worry about your baby. He or she will likely just have to figure out how to play an instrument when his or her fingers are crooked. The only real problem it gives me is on my outer toes because I am basically walking on them all the time and they get sore and blistered if I run or walk long distances.
No one on November 26, 2017:
I've lived with both of my hands having a identical curvature on all figures besides the thumb. My grandmother, her mother, and my father all have the exact same as well. Each finger has a different degree of curvature (for example my index finger has a significantly less curve then my ring or pinky finger) I have not been told I have any mental issues besides depression and issues pertaining to that but other than that I am fine. I have been an extremely artistic person for my entire life, whether it be with painting and drawing or even more recently with the interest in creating and writing films. My case has been said to be extremely rare from the curve of each finger and them being identical on each hand, but I would like to know who else is out there that have the same kind of fingers as me.
Jess Maddison on February 01, 2017:
I have this condition. It is most commonly found in boys and it is rarely found in both hands. Also, although it is more common to have Down syndrome and clinodactyly, there have been many cases in which those who have this condition do not have Down syndrome. I don't have Down syndrome, I am a female and I have it in both hands so I guess I'm just really abnormal. This condition is to do with the allignment of the finger joint and plates, it's usually caused by an abnormal Orientation of the growth plates of the hand. It isn't linked to creativity, it's just the abnormal growth plates.
Hope this helped:)
Crooked pinkies on January 20, 2017:
Hey there. 30 female with bilateral clinodactyly on fifth finger. I've played guitar for about 15 years. 130 IQ. Dominant hand has slight irritation by the end of the day, but no major problems. Nice to finally know why my little fingers are crooked :)
Matt on January 17, 2017:
I have this, so does my mother and grandfather, its genetic, and there is absolutely no link to any mental issues. If anything judging from these comments, it seems to have the opposite correlation. The only problem it has ever caused me is my guitar playing could be 10-15% more efficient/better if I had my left pinky straightened.
Jaime on January 11, 2017:
I have crooked pinkies, as does EVERY child born on the paternal side of my family. We have gone so far as to joke about knowing parentage based on whether a child is born with crooked pinkies. And while I have also read that this "disorder" is associated with higher instances of other syndromes such as autism, down's, mohr, and seckel, to my knowledge not a single person in my family has ever been affected by these things. The majority of us are college graduates and professionals.
Lisa F. on January 09, 2017:
My child has Bilateral fifth finger clinodactyly, and has a 130 IQ, and is transgender MtoF. She is 15 now.
Andrew on August 24, 2016:
I Have curved pinkys on both hands as well as curved ring toes on both feet, When I was young I was diagnosed with ADD but that is not retardation so I dont know if that has to do with anything
Amanda on July 15, 2016:
I have bent pinkies, so do my brothers, my mother, my grandfather, and my great grandmother that I know of. So yes it's genetic. But, I do not belive it has anything to do with mental retardation. I was labeled GT (gifted talented) in kindergarten and have been ever since. None of my family has ever been mentally challenged. I had no idea that this deformity had a diagnosis until researching it just now. It's never been a problem, it's just a little strange. My doctor has never said anything about it, and honestly it think it's kind of stupid to get surgery on it unless you physically can't use it.
Kikijo on April 07, 2016:
I have bent pinkies, never thought there was any issue. NO ONE ever said so.I was told it was genetic, just the way my fingers are. My son born this way too.. Both pinkies..
No issues at all.Everything normal.. Didn't know it had a name until recently, and was shocked to find some doctors make an issue of it..
Not sure about my siblings. We never spoke of it, and I never noticed..
I would suggest it is a genetic trait and with DNA some day they will find we are all related.. And that will be the sum total of the whole bent pinkie situation...
Carrie on March 30, 2016:
I just wanted to add that my son went for speech therapy and had appointments to check for autism...he has now been taken off speech therapy cause he's at the learning area he should be which is the same at school. So they have no worries there apart from some of his sounds but thats more because of his lisp. Doctors and specialists say he is not autistic, but sometimes this isn't diagnosed until they're about 7yrs old, so I'm not ruling that out completely yet. He is a very lively on the go boy who is into absolutely everything, he whinges and whines a lot, he also suffers from constant colds/coughs. Had croup a lot as a baby. He has since had his tonsils out as they were over enlarged for his throat which was pushing his tongue forward, he's had adenoids taken out due to his breathing being so bad and he has also had grommets put in to help with his hearing as we were unsure if he was hearing properly. The hearing is so much better now but he is still suffering with his nose so I've no idea what to do there!?!? You just worry that this is all connected to a more serious problem especially when you look up Clinodactyly....Any advice from anyone on how I should be feeling is very welcome. Id love to hear from you :)
Also how do I upload a photo, I'd like to add a pic of his bent pinkies?
Carrie on March 30, 2016:
Hi I noticed straight away that our son had bent pinky's on both hands when he was born, I thought nothing of it at first but as he started growing he showed problems with his tongue (hanging out all the time until he was about 14mths) he had trouble with his speech, he is nearly 5 now and still struggles with certain sounds and he also has a lisp. Other than this he is a very clever boy and very forward for his age in his physical abilities, and his memory is amazing, he seems very creative and loves role playing things out.
I looked into it online when he was young and found clinodactyly and realised it was this, I pushed for genetic testing to make sure he was ok and had no type of 'syndrome' tests came back all clear. Its all very strange as I don't know of anyone in the family with this problem, not that were aware of anyway. I still have worries that something isn't right as some sites say you need to keep an eye on their behaviour etc as they grow up...Do I need to stop worrying!??
Amanda on January 01, 2016:
I have very crooked pinky fingers. I've never had any learning issues other than delayed reading (though it was probably more to do with disinterest on my parent's part in teaching me) and I've always committed things to memory by using the information in musical rhymes, rhythms, or songs. I have always had an artistic mind, and have not only played the violin for 21 years (I'm currently 29) but I also have taught lessons since I was 13. My mother also has slightly crooked pinkies, but is less artistic/musical by nature. I've never seen another person with crooked pinkies, and anyone who notices tends to think that it's odd, gross, or that I've had some sort of injury.
HairFreeTx.com on September 30, 2015:
We all inherited from 1 mom clinodactyly, both hands with bent in baby fingers & we R all very sports active, creative, & bright... Dont let the information out there make you believe something is wrong with you.
Kim on September 10, 2015:
My pinkies are crooked and a wee bit shorter than they should be, well as a child of the science fiction generation it was said as man evolves they will loose the pinkie and ring finger so I just assumed I was higher on the eveloution ladder than the rest of the folks around me.
MJ on August 30, 2015:
I have it too. My grandfather on my mother's side has it, and my mother had it. We both have a variant form of rhumatoid arthritis, but this developed in our early adolescence. I have musical, drawing, writing, abd creative problem solving skills.
Angela on August 13, 2015:
I inherited mild clinodactyly from my mother, who thought that she got it because grandma took too much calcium while pregnant. I have it in both index fingers and my right pinky, which also has a large knuckle. It is always stiff first thing in the morning along with my other fingers. The joint attaching the pinky to my hand doesn't operate smoothly - it just kind of pops back and forth when I move it. Weird! I am concerned about developing arthritis, but so far so good now at age 47.
Angela on August 13, 2015:
I inherited clinodactyly
Debbie Pyykkonen on July 19, 2015:
Both my sons and their father and grandfather have this. My oldest sons are to the extreme
Carl R on April 03, 2015:
Just to assure worried parents: I have clinodactyly in both little fingers at a noticeable angle for the top section of 28 degrees (I measured it in junior high school, and every few years). I am 64 years old.
My mother had it, my brother has it, both of my daughters have it, my grandfather had it, some cousins on my mother's side of the family have it, and some of my daughters's second cousins have it. Clearly it is hereditary. Interestingly, only one cousin's daughter has it at as large an angle as I do. Others seem to have it around 15-20 degrees (no one lets me measure it :^)
Not one relative has any other syndrome that is supposedly related to it. In fact, my brother, daughter, and just about every cousin and cousin's child with it has a Master's Degree.
My parents tried using wooden splints on them when I was 3 years old, but it made no difference. But to reassure people, it has not given me or anyone else in the family even one problem, other than not easily being able to reach beyond a 9th on a piano (which many famous pianists, alas, can do easily; Gershwin was famous for his 11ths).
I hope this allays some people's fears about it.
Josh on April 01, 2015:
I have a little girl that is 3 yrs old. I noticed her curved pinkys when she was born. One is curved more than the other. It doesn't hurt her she says and is really smart, excellent tlking and impressive sentences since she was like 2. Im just wondering if i have to get it fixed or if it doesn't bother her is it ok?
She is very special and stands out. Loves attention so im positive there is no syndrome of ne kind but im not a doctor. Does it need to be fixed or is it ok?
Liz on March 30, 2015:
I have clinodactyly in both pinkies, and they are sharp angles, almost every person on my father's side has it, including my two sisters. Most of us also have a large torus palatinus. Mostly this side of our family are highly intelligent persons, engineering is a common career.
I like to also consider myself very bright, I have a fast learning curve (to the point I become frustrated with teachers as I can pick it up faster "thinking through it" than they can teach it to me...), and a scary intuition (meeting someone in person for five to ten minutes I am 90% accurate 90% of the time in figuring them out - this makes it possible to predict and manipulate other's behaviors, not that I am evil, just a skill I don't think many others possess :)
My 13 year old son also has bent pinkies and has autism. He's intelligent, but classical symptoms of decreased social skills and maturity, mostly non-verbal, and heavy OCD. My younger sister has two children with different fathers, one with autism and one not. My older sister has two children, same father, no autism. Genetic testing has told us nothing, but maybe someday.
Shawna on March 11, 2015:
My husband has clinodactyly in both pinkies. He passed it down to our first and so far only child, a son, who is now 12 months old, who is also affected in both pinkies. My husband is normal in every sense of the word and my son is on time or advanced in all developmental milestones, no sign of delays or lapses in any way. Sure, for some, clinodactyly presents itself as an additional feature to a disorder, but on it's own it is not a marker for any problems whatsoever.
Mike on February 22, 2015:
Crooked pinkies are not a designator trait. which means anyone of any intellect and motor skills can have them, and it doesn't mean they have any kind of "syndrome" or autism. Its actually a dominate trait, so more and more people will have it over time.
Maria b on January 19, 2015:
I have been beyond stressed with the fact that clinodactaly is linked with autism. My son is four months old and I am convinced he has autism. Everyone else who meets him thinks I am crazy. I just wish I could know for sure but there is no telling until later.
dad of pepper on January 05, 2015:
our baby was born 3 days ago, with very crooked pinkies. will bookmark this page for future reference. thank you.
B Love on October 18, 2014:
My husband and all three of our children, as well as his father and siblings, show different degrees of clinodactyly. My son also has curved toes. None of these people show any degree of mental retardation. My husband and son exhibit signs of ADHD. My husband is a musician and teacher and my son is creative with art and drawing.
Sal on October 13, 2014:
I wrote on here about 7 months ago now, I said I would update, so here it is; Consultant Paed Dr thought our daughter probably (who has clinodactyly and had feeding problems from birth) had Russell Silver Syndrome (RSS). On June 13 2014 we had a referral appointment with a geneticist, she said that our daughter was not presenting with RSS, I was very relieved as I could not relate to the stories of people who have children with it and I just could not see it. So they have finally stopped looking for syndromes and go by her weight and length which are in the normal range. We just had a review where by I hoped our daughter, now one year old, would be discharged from outpatients, but they would not, much to my protest. So now, if she continues to thrive and grow they will discharge her in six month's time. The most upsetting thing is that the geneticist wrote to the Consultant Paed Dr saying that our daughter does not have RSS, and that she understood from talking to me that I, the mother, was stressed from all the focus on my daughter's slow weight gain and that perhaps this could be a factor. Well, having people labelling your child with a syndrome is stressful and especially when you can't see it yourself and have had all this focus on your child's weight gain just becuase it was not following a centile, it has caused a negative impact. I did say to one of the Doctors that I really did not think there was anything wrong with my daughter and I just got a wry smile and nod as if to say "Be quiet". Basically, it counted for nothing and no one was listening to me. Stressful is not the word, but sadly it does appear that midwives, health visitors and doctors all seemed to think there had to be something wrong as her weight was not following a centile. Shame that my opinion as her mother counts for nothing, what happened to "Mum knows best"? Well, it turns out I do know best, she is fine and continues to grow and is achieving her developmental milestones, no problem. She is a long slim baby and takes after her father who is tall and slim. It was so obvious to me, but none of the professionals were interested in what I thought.
Well, that's good news really, she does not have a syndrome. She is an interesting character and people always say she is going to be a creative soul - well, that remains to be seen. Perhaps I will do another update in about 6 month's time. All the best for now!
Meme on September 30, 2014:
All 3 of my grandchildren were born with pinkies bent on both hands. My Mother in law also had bent pinkies. My grandson was slow at first, he didn't walk until almost 2 yrs.old but once he started he took off. My Daughter put him in school at age of 3 and by 1st grade he was a whiz. He is about to gsrduate high school at the age of 17. He loves school and my 2 granddaughters also aredoing great at school. The all love music and have played instruments in Band and participate in choir. Hope this helped. They aren't geniuses but they do make a's & B's usually. Good Luck.
Jessica on September 20, 2014:
I find this information very interesting! My husband has clinodactyly quite severely (pinkies are almost completely bent sideways towards the ring finger). My 5yr old daughter also has this but not as severe.
Although excellent with math, my husband is not artistic or creative and great difficulties in school (dyslexicia, , learning disorders, ADHD). He does have the ability to figure out how something mechanically works and fix it with zero prior knowledge. My daughter is artistic but had great difficulties (developmental delays, possibly autistic, failure to thrive) as an infant/toddler. Now, as she has just begun kindergarten, it's becoming apparent that she may have some learning difficulties as well to compound things.
I do not know if or how clinodactyly may factor into our situation or if it's simply an issue of genetics. My husband is of German and Irish origins. I believe it's worth noting that he is left handed and I wonder how many others with clinodactyly are left handed?
Michael on August 07, 2014:
I have bent pinkies on both hands, my grandson does also, I have no mental issues that I'm aware of nor my grandson, I am musically inclined, playing several instruments, I am college educated, did well in school and the military , my grandson excels in martial arts,music,science, mathematics, and was accepted into duke universities talented and gifted program at. 8 yrs old, I'm thinking this is just a heriditary birth defect
DakotaFox on August 02, 2014:
Both of my pinkies are bent and it's never affected me and I'm 7 years in the Army and re enlisting
Sarah on July 27, 2014:
I am of English decent. My pinkies & second toes are bent. Very noticeable. I am 23 and have never researched what it is or what causes it til now and I am glad I did. As a young kid I picked up things very quickly more so than my sister which doesn't have Clinodactlyly. I was always a bright kid but my attention span wasn't great, worst in high school. Teachers would always comment saying I never reached my full potential because I was always day dreaming. I have a love for music and art but I'm not great at it. It takes me a few goes to get something but once i get it Im good at it. I also tend to give up if i think i cant do something. I am really good at a lot of things but not great at one specific thing. I haven't found my true calling yet but it has opened up a world of possibilities for me. I don't have kids as of yet but my partner also has Clinodactlyly and my mum. I don't think it has links to syndroms or autism. Thanks for the blog :)
Mary on July 19, 2014:
Both my middle fingers curve towards my ring finger. I didn`t notice it till only just recently. Would this mean I have clinodactlyly?
Kas on July 03, 2014:
I am 28 and both my pinkies curve inward very noticeably. I had to laugh about the "propensity to be artistic, creative, etc" as I've always been talented and passionate about: Drawing, painting, sculpting, acting, music, and story telling. I guess I can thank my crooked little pinkies!
Plus, when I was a kid I kicked butt at hide and seek, nobody realized I was peaking through my pinky gaps ;)
Lindsey on June 18, 2014:
I'm 31 and both of my pinkies point inward towards my ring finger quite noticeably. As far as I know I have no learning disabilities...unless you count choosing to teach 9th grade English a mental hiccup :) I have ways been quite musically inclined; I played the flute for many years and am often called upon to sing at weddings or sing the National Anthem at various sporting events. The only odd thing my pinkies have caused me is the fact that I snap with them...thumb to pinkie rather than what finger everyone else snaps with!
ashley on June 07, 2014:
I have this. Both my pinkies are curved towards my ring fingers at a very noticeable angle. No one else in my family has had it I was the first. I'm not musical or artistic. I guess I could be creative but I doubt that has anything to do with my pinkies. I am not mentally challenged in any way shape or form. I actually graduated with honers. I have three children and expecting another. My oldsest has the same condition and it is very defined as mine is. My middle son has this too but it is not as defined. And my youngest son doesn't even have a little curve. His pinkies are perfectly straight. All my kids were born premature because a lack of a hormone I need to produce to go full term. But non of my kids have any mental problems at all and no signs of any mental conditions. My oldest is about to be 9 and my middle just turned 5. So I wouldn't worry about mental retardation at all.
J on May 07, 2014:
I have two very crooked pinkies. mine don't curve so much as suddenly aim inward at the last knuckle and i am an accomplished writer lover of music and art. i also have asperger syndrome (a form of autism) I'm 25 have two children and function very well
Stephanie on March 31, 2014:
My son is 4 and he has bent pinkies on both hands and his feet. He is just barley behind on his intellect but head start is bringing him ahead now. He also as a mild speech problem but he is very hands on and articulate. He also has very good fine motor skills. And can do and understand almost anything. He's very smart, sweet, and artistic. I've always noticed his pinkies being bent but I didn't know it was considered anything until 20 minutes ago. I appreciate this site with this info. Thank you.
Val on March 21, 2014:
My daughter has two curved pinkies. I just happened across this information today and did not even know this name Clinodactyly existed! WOW! She is six almost seven and I homeschool her. She is a born actress and prima donna. She takes ballet and jazz and tap. She is very tall for her age. She also has a port wine stain on one hand and also had a hemangioma (large) on that same arm. Those have diminished with time although she had quite a few surgeries on the hemangioma in her first year. She was born five weeks early. She is a whiz at math but struggles with reading some but I think mostly that is because she would rather be out of her chair singing and twirling and dancing. She is so imaginative and creative and can already sew intricate type things. I am so very excited to have found this information today. It just fits. Thank you! I have so enjoyed reading the other posts!
Sal on March 06, 2014:
My five month old daughter has Clinodactyly on both her little fingers. She has had feeding problems and was not gaining weight within the centiles. Paediatrician now thinks she might have Russell Silver Syndrome. I am not so sure, she is perfectly normal otherwise and seems to be slightly ahead with her development milestones. I think paediatrician may be wrong, as we have been advised to wean and my baby is now feeding fine so long as she is not fed milk from a bottle. Thing is when she was a month they said she had Turners Syndrome, she was karyotype tested and everything came back negative, so it is a pity to now face yet another possible syndrome. I suppose only time will tell, for now I am going to enjoy my perfectly happy beautiful baby girl. I will write again at some point as developments happen. All the best for now.
Genna on February 24, 2014:
I only just discovered there was a name for this! Wow! All these years, 33 years I just thought I had my hands clenched too tightly in the womb and that is what had caused the bent pinkies. And now I discover it's a genetic thing (hate the word defect) and it's called Clinodactyly!
Just to add like everyone else has here. I had no developmental issues. I was always an above average student and am now successful in my field. It is a creative field - so I don't know if that helps with your research?
kam on February 21, 2014:
I see where most are the pinkie finger. I was born with my index and middle finger curve toward my other two. Going out. And on both hands. Odd.. I'm Scottish decent. My 2nd son inherited same as mine on both of his hands. I have no trouble with them except I don't like it. Does anyone else have this?
yuri on February 18, 2014:
my son and i both have our pinkies curved. So far I have not noticed any delays with my almost 2 year old son. Infact he is very advanced in all his milestones and he is very creative , artistic and loves listening and dancing to music. I am very artistic and creative as well. I love arts and crafts. No one in my mother side or my mother has curved pinkies, or have any disability or disrder. I never met my biological father so I wouldn't know if it runs in his side of his family.
Tom Samson on February 14, 2014:
Im 19 and have always hated having my bent little fingers. They haven't ever really seriously got in the way of my life but they can be annoying at times (trying to play bar chords on guitar, trying to grip the bow on a violin). I find that because they are bent I cant put as much pressure on them without them buckling (because of the shape) and because of that I find that I don't use them. For example when carrying bags etc, I tend to find i'm only using my first, second and third fingers. Because of this I think my little fingers have become very weak and maybe even stunted their growth?? Plus most people are grossed out by them so I have a slight insecurity about them.
In regards to the hereditary side of things, neither of my parents or grandparents have bent fingers or mental illness. However my cousin has bent little fingers that curve outwards rather than inwards which is interesting. I myself was a month premature at birth so I've always assumed it was because of that.
At university currently, studying Electronic and Electrical Engineering, so I assume i'm of at least average intelligence. I play guitar and sing a bit, but I wouldn't really say I was that musical or artistic to be honest.
Alyssa on January 03, 2014:
I'm 25 and never spent much time wondering about my pinkies until now. Honestly it's amazing to see that so many have this pinky because I thought I was the only one. No one in my family has it on either side that's alive, so I'm not sure if it's a genetic thing so much as a birth defect being that no one in the multiples of generations has it. I'd say I've always been intelligent, mostly philosophical and a whimsy creative at heart. No learning disorders in my lifetime, in fact I was always ahead of the curve. I also have a 3 year old daughter who does not have this pinky. My mother does have Spina Bifida and curled toes though, so there may be possibility of a genetic correlation with that, but her toes were original straight until her spinal cord began causing nerve damage (she didn't know she even had the disease until she herself was 25). According to folk lore and palmistry these pinkies represent psychic ability and intuitiveness. But who knows? Very interesting.
Beth on December 20, 2013:
My mom and dad have slightly crooked pinkies, but mine are definite. My sons hands look just like mine and he is very musically inclined, like me. He also loves to build things with legos, or about anything. He has been diagnosed with ADHD, but not autism.
Mike on December 12, 2013:
I was born with this condition, and from what I was told it can be genetic. Apparently my great-grandmother had it. My condition is a actually quite profound, but I'm 43 now and I've suffered no ill affects. I can attest to the theory that, at least with me, they're linked to artistry. I have been in art classes since kindergarten and I studied Theatre Arts and Film Production in college. The closest I came to anything remotely linked to mental retardation was a minor case of ADD, sprinkled with a major case of procrastination. But who isn't diagnosed with those these days? I didn't get the best grades in school because I was always daydreaming, being imaginative and creative with my mind... thinking of other possibilities, and of course other things I would rather be doing. So, I did have some academic and some self - motivation challenges, plus I found it a little difficult to play the guitar or piano, but my artist side shined. I also like to have fun with people when they're sharing their double - jointed abilities and show them my pinkies. Sometimes I tell people I'm not from Earth, but from an advanced race of people whose clinodactyly is common and our technology can only be operated by people with bent pinkie fingers. :)
HHH on December 11, 2013:
Hi everyone. I've found it very interesting reading all these posts. I have 3 children, 2 boys and 1 girl. Both my sons' pinkies are curved. And for me, I'm their Mum, I have slightly curved middle fingers (toward the ring fingers) but my pinkies are very straight as well as the rest of my digits (toes and hands) and they're long and skinny. Our daughter does not have any curved digits nor does their Dad, my husband. I have Irish, English and Faro Islands background. My husband has Scottish, Swiss and Chech ...perhaps more but ?
Our son who is now 8 is above average in all subjects at school (far advanced in reading and math). He is very social, and has been since a small baby, clear spoken, musical and always had incredible balance! He walked at 9 1/2 months old and we lived in Hawaii and he could stand on a surf board in water with small waves at age 1.... surfers were stunned! That was really fun. His younger brother who is now 3 1/2 years old is very similar especially with the balance (riding a bike at 2 1/2) only I would say he is VERY musical! We do the Music Together program if you know of it, it's world wide, really great program... he memorizes all the songs and sings on key and rhythm. Also, I sing with a chorale and he memorizes parts of the pieces I practice like O Fortuna from the Carmina Burana! This all sounds like bragging.... These are just characteristics that fascinate me about our kids. Who knows if it's the curved pinkies.... but it's a fascinating question! I can't say that in our case curved pinkies are of any concern whatsoever.
Cheers to all you curved digit people!! And thank you for all the interesting info. I loved ready others stories.
Dawson S on November 20, 2013:
I've often wondered about my bent pinkies (both), but since everyone around me told me that it wasn't weird, I just ignored it for years. But after reading something about clubbed thumbs, I decided to google "bent pinky finger" and there it was! Clinodactyly! I measured my fingers with a compass and I believe my pinkies are bent at 30 degree angles. I was born premature (I think 6 weeks or maybe more), and I showed signs of slow development in my early life and my parents and the doctor thought I would end up with some kind of retardation. Through the power of prayer (sorry skeptics and atheists), I began to show improvements, and at 18, I am an extremely good student. I've never had an IQ test, but I honestly believe I'm definitely above average. Still, this could have explained my pinkies. Also, though I'm an American, I have a great deal of English, Irish, and Scottish blood, so maybe it could be a regional thing hidden in my genetic code and passed down to me. I do also love art. I draw, paint and write both prose and poetry and sing. Not to mention I'm only 5 ft .9 of an inch and there is no likelihood that I will grow any taller. Wow. It's crazy to think that we all have so much in common, and we were brought here because of our oddly shaped fifth fingers.
betsue48 on November 19, 2013:
I am 65 yrs old with several college degrees & love of art & music. Both of my parents had crooked small fingers. We are Scot-Irish and German descent. I met a woman from Wales and she told me many villages in that part of Great Britain had people with clinodactyly. I was told in 6th grade I had high IQ, but never knew score, because teachers were not allowed to tell students at that time. I am short, 5 ft, & only 4 lumbar vertebrae. Don't know if any of that is related. The only thing I know I can't do is play piano because little fingers are too short. I'm proud of being a little different.
Shokun on November 18, 2013:
I am 29 years old, I have bent pinkies on both hands. was being tuitioned at British council since my English sucked, the teacher decided to give us a Mensa test, I topped the class with 149 score, surpassing those at prestigious Secondary school, btw that was when I did not get the tricky english IQ question. I learn Maths on my own since child, even score A* in Cambridge. However, as I grow up, I become a Day dreamer. So much of thoughts yet little strength to change anything.
I should probably stop thinking and write a book or do something. oh btw I am Asian Chinese. Heard from Fortune teller saying bent pinkies people are usually homely and filial people.
I have a creative handwriting that is readable but you need to tweak your mind in the way like Arts! Music is my holy grail, love to sing too. Good at sports but not a very active person alone. Cooks well. Repairs or DIY things easily.
In my family, I am the only one with ezcema, premature birth, being tallest. Many nightmares when childhood, then as grow up becomes a lot of dreams, experienced Jumper even before Jumper movies screened, Inception though not the Inception however I managed to use dream within dream to score my Java programming from D to A+. The theory of Inception is true when you spend more time in the 2nd tier dream and wake up to find out you only spend 5 hours in reality. But that incident only happens once. Probably I worried about the exam too much that this reaction kicked in.
Ryanne on November 15, 2013:
Everyone is saying that either their child is mentally delayed and has it, or they're very smart and have it. My sister isn't delayed, but she also isn't a genius and she has it. I also have crooked pinkies, but I'm taking college courses as a 16 year old, so I guess I can't really judge on that part. I wouldn't consider myself to be that smart, though. In any case, neither of us are good at any form of art (we can't draw or sing, and, even though I took guitar lessons for the better part of my life, I still can't play a guitar very well), and we also aren't delayed in any way. We both have hypermobile joints, too, but I think that's unrelated.
I had a doctor that once tried to "fix" my fingers using a system of casts, but they didn't really work. That doctor thought that the curvature of my fingers would lead to them becoming useless, but other doctors said that that one just didn't know much about the subject. That was a few years ago and I'm still perfectly fine.
Also, I work with special needs children. I've never noticed any of them to have crooked fingers, but I'll definitely be checking for it next time I go to work!
Laurie on November 15, 2013:
I and my 5 siblings all got Clinodactyly from my Dad!! Definitely can say that is the dominate gene in my family. My dads are the most crooked and small. I am the oldest, my pinkies are a lot like his. The 4 kids in the middle have crooked pinkies but are a little longer, less noticeable. Our youngest sister has down syndrome, all of her fingers bend in odd places. Her pinky fingers though....man oh man....she fits right in :) The 5 of us without down syndrome are very talented in different ways. I am a super athlete, #2 is an artist and model, #3 is athletic, personable and very funny, #4 loves music and teaches himself all kinds of instruments, and #5 is straight A's miss popularity. I read above someone's husband likes his crooked fingers to grip easier....I believe that's true, I think that all the time!!! :)
Honor Bear on November 10, 2013:
I have it slightly on both pinkies, as do my siblings and everyone on my mothers side of the family! There is no history of any 'mental retardation' or anything else within my family.
My fathers side of the family all have their middle fingers bent at the top, out towards the pinky. So me, my sister and my brother have both middle and pinkies slightly bent!
Karen on November 05, 2013:
I have twin boys three and a half years old. They both have curved pinkies and their two older brothers do not. Thank you for starting this hub cause I can read anything online and suddenly my children's health is at risk. My children are all very intelligent and the twins are very creative and imaginative. This has made me feel better and I can sleep the rest of the night. I will still check in with the doc next time we are there...
Cheryl on October 21, 2013:
I am 56 and was born with short pinkies and the left one is more crooked than the right. I never thought about this being part of a syndrome until a friend's daughter was diagnosed with a syndrome (Noonan's); and I thought maybe this is something more than a crooked finger. I have a BS degree and have been a health care professional for 32 years. When I was a kid I used to worry about my husband seeing my crooked pinkies when we got married (when he put the ring on my finger) . I don't think he has ever noticed. No one else has noticed, either.I have had a fantastic life. Everyone's comments have been very helpful. This is not something to worry about.
adam griffiths on September 30, 2013:
my IQ was tested when I was younger and I was 118
adam griffiths on September 30, 2013:
yeah I didn't know wat the name for it was but i have been born with bent fingers and toes im 27 now and I have a 2 year old son who also has them I don't have autism but I do have ADHD.
Finland on September 21, 2013:
I'm a 17-year old male of nearly purely German and Swedish descent, with bent pinkies, blue eyes and blond hair. I'm roughly 5' 10" (~175 cm) tall, my IQ is 152 (according to the culture-fair Mensa test), I tend to beat my peers at chess and am one of the best students in mathematics and physics in our school. I'm also a self-taught C/C++ programmer, been programming since I was 11 years old, capable of writing more or less any programming language that comes my way on a professional level. Maths, linguistic skills and problem solving have always been my strengths.
All my family from my mother's side has had bent pinkies, my grandfather used to be one of the best chess players in western Finland back in his days. His IQ also was somewhere around 150.
It most certainly isn't a bad genetic trait, even though several studies have found relations between bent pinkies and autism, I believe it might increase the chance of being autistic but I think other genes also play a major role in it. I don't think that it's a "genetic disease" at all, I nor my family haven't had any health problems. I know a few people who also have bent pinkies who also have their IQ much above the standard deviation.
Anna222 on September 20, 2013:
I have bent pinkies and webbed toes,both my parents have bent pinkies,my dad has two completely webbed toes and i have same disorders as them and people with bent pinkies usually have down syndrome about 80% kids with clinodactyly have down syndrome,but i don't.about 7%-10% of people in the whole world have this genetic disease. Anyways im healthy even though i have clynodactyly and you shouldn't worry about ur daughter shes going to be perfectly fine also i read that people with clinodactyly are usually short (i am very short so) and i also have webbed toes :D
KelBell1919 on August 01, 2013:
I am a 33 year old female with crooked pinkies. I am mostly of German decent but also have Norwegian and Irish. I inherited from my father and we have the exact same curve. Recently, I discovered my male cousin has the same crooked pinkies; he is also on my father’s side of the family. I am not sure if my grandfather or grandmother had curved pinkies. But it is pretty dominant on my dad side. My right pinkie is slightly more crooked than the left. I do not have autism or any other mental disorder. I am not very artistic, however, I can draw a stick figure like a champ! I am not a genius and have no idea what my IQ is. I majored in Chemistry but I studied hard to get good grades. My father makes furniture, he designs and then builds. He was a mechanic for 35 years before computers took over. He is a horrible speller but is amazing in math and geometry. Good luck to you.
John on July 01, 2013:
I am in my 40s and both of my pinkies are bent inwards at about 45° on the last knuckle
I am Scottish. Last time I did an IQ test it was about 140.
I am particularly good at logic/maths/problem solving
I have very good motor skills
from martial arts
I never really gave much thought to my pinkies they are just part of me
Sam on June 27, 2013:
I just found out that my grand-mother and I have the same crooked left pinky! Nobody in my life has ever mentioned it or even noticed it except for her.
I have it, I'm not sure if my mother has it but my grand-mother told me she has it, her mother had it and my grand-mother's grand-mother had it too. We are Americans of African decent.
None of us have any mental deficiencies nor have any of these women given birth to any children with any of the above mentioned mental deficiencies. The same goes for the second, third and fourth generations. Basically, they had healthy babies and their babies' babies were healthy and so forth.
As for me, I learned to read by the age of two. By time I was I was in first grade I could read basic sheet music, communicate in English, Spanish and ASL and wrote my first computer program at 7. It wasn't anything too complicated, a few prompts using BASIC, however, I do not think I would have passed for mentally deficient.
Today I am an artist. My grand-mother with Clinodactyly taught me how to use a 35mm camera when I was young. She is the most creative person I know.
Cindy on June 22, 2013:
Your daughter's pinky looks almost exactly like mine!
Joe on June 12, 2013:
I also have two bent pinkies, and at 62 they haven't changed my life much. When I was young, I was very aware that I was different with crroked fingers, so I got into martial arts to the point of breaking boards and bricks. So when someone inquired about my fingers, I just said they had been broken several times praticing Karate. They make for intresting conversations.
j.lee on April 19, 2013:
I am a 26 year old female with bent pinkies (the right more bent than the left). I don't think mothers with small children with this "defect" should worry about autism or down syndrome. I have lived a perfectly active and social life. In high school I was co-captain of the tennis team, president of a service organization that had over 200 members and valedictorian of my graduating class of 749 students. I graduated from UCLA with honors and was vice-president of my co-ed business fraternity. I am working in finance now with type A people and I earn more money than most of my peers. The pinkies have never most gotten in the way of anything. I played the flute and piano as a child and although the bent pinkies made it a bit more difficult...nothing more practice and determination couldn't overcome.
Matt on April 07, 2013:
I, my mother, and my younger brother all have crooked pinky fingers on each hand. We are all extremely creative and pick up on music very easily, we are good cooks too. Music is second nature to me.
runner76 on April 07, 2013:
I am 36 years old and have crooked pinkies on both hands; with the right-hand pinky apparently craving more attention than the left as it is considerably more bent- and proud of it ( and consequently, so am I!). I grew up a normal child; definitely on the creative/artistic side (which I dismiss as anything relevant, as many people with straight pinkies are also creative and artistically inclined) - I was perhaps a bit more "aware" than my peers at any age...but I would dismiss that as an influence of environmental factors, more than anything. For me, my crooked pinkies have always been something to be proud of; something that set me aside from everyone else. It also made me proud, because it created a concrete connection/bond to my Dad's side of the family; my Grandmother (his mother) had it, I have it, and my cousin's son also has it. During one of my routine visits that my mother took me to see my pediatrician when I was 10 years old or so, he examined my fingers and told us that we could have the fingers broken and corrected if need be; however seeing that they produced no issue functionally, there was no need to put me through that. And I am so glad that I didn't - these crazy fingers are mine - and I'm so glad that I have them! They not only make me different from anyone else, but more importantly, they are a constant reminder of my family; my heritage...and the generations before me who I am blessed to share this trait with (my sister wasn't so lucky!). In conclusion, the worst thing (and it really isn't that bad - but I'm sure that others with crooked pinkies can definitely relate) that has come from me having these crooked pinkies, has been that same old question throughout my life: "What happened to your pinkies - were they broken????" To which I always get a chuckle.....in the meantime, while others spend their time analyzing my crooked digits, I am focused on training for my next marathon. :-)
Ruth on March 27, 2013:
I have a 3 yr old son with very bent pinkies on both hands. He does not have autism but does have some digestive issues and food allergies. Anyone else notice a correlation between the two? I read somewhere else that there might be a correlation between Clinodactyly and Chrons disease.
Gemma on March 27, 2013:
I have a 9 year old daughter with curved pinkies of both hands as well. We call them her Special fingers, they have never hampered her ability to write or anything. She is very creative and musical, but as her Father is a musician and I am an artist, it's kind of to be expected! :)
She is also intelligent, and also loves science. I have never been worried about Autism or other issues. I have not noticed any other bent fingers in our families but when I read that it was heredity I checked out my toes and discovered that two of them are bent! So I guess that's the same thing. As to the Celtic issue - on her Father's side we have Scottish but also Indonesian, my side is mainly British. We have not noticed any other bone problems!
Sharon on March 26, 2013:
My 8 year old daughter has crooked pinkies in both hands. She is the only person in our families to have this trait, and is also left handed. No other physical or developmental abnormalities-in fact, she is extremely bright, creative and witty. Loves art, science and math, and very sociable. I often wondered if they were due to her being 8 weeks premature. Have no idea what may have actually caused it--her father is from Scotland and I am of British descent-maybe it's the conflicting, crooked heritage lol!
De on March 22, 2013:
Hi - I'm 31 years old and both my pinkies are bent. I am very creative, have a high IQ and have no physical problems related to the condition. I think it's not necessarily a marker for developmental delay but keeping a close watch and talking to a pediatrician is always good. Good luck !
kelly on February 26, 2013:
I have crooked pinkies on both hands. I am 52 years old (today!) and have never had any problems. I have a PhD in psychology and am a pretty well-adjusted person. I personally think having crooked pinkies is kind of interesting, but that's about it.
Maggie on February 18, 2013:
My DD is 12 mo old and has one bent pinky finger (left hand). She is just starting to walk, so not behind in milestones, and is extremely social and engaging with others, always smiling/waving/making eye contact. I was concerned after googling it due to the references to autism, but I have no reason to believe she has autism. I will bring all of this up at our upcoming 12-month checkup.
nancy on January 24, 2013:
my 9 month old daughter have bent pinkies and she is excelling and hitting all milestones quickly. she has already stood up on her own and will probably be walking by 10 months. she isn't autistic. she is extremely engaging and loves music. she already tries to dance and grooves while she is sitting (when i am playing music). my husbands pinkies are also bent and he is a finance whiz.
Martha k on January 05, 2013:
My daughter has this yet she does not have any learning disibilities in fact she is one year ahead in her studies and the teacher has suggested that she be moved up a grade. Me and my husband have always wondered why both pinkies were so crooked this website has been very insightful.
Adam on December 31, 2012:
I have Clinodactyly, and have no particular statistical oddities to mention. I believe I had my IQ tested when I was around 16, which turned out above average (although I think it's a bit overestimated). I am a fairly normal person, a little bit disorganized maybe, but really a very average person overall. While I wasn't surprised to see that there were genetic links between Clinodactyly and other conditions, I was surprised at the abnormality of the conditions. Clinodactyly runs through my family, all of whom were fairly successful normal people. Which makes me question this article. How strong is this statistical correlation? Does the author, or any others on this hub have any studies or references which I could see to back up this information?
hmckim on December 22, 2012:
My oldest son (4 yrs 10 months old) has clinodactyly. I noticed it the minute he was born. His peditrician told me it was fine and nothing to worry about. She didn't even tell me the medical term for it. I did not know it was a trait for down syndrome either. However, my son is advanced for his age. In his preschool class they did an evaluation and he's learning at a 5 and 6 yr old level. He rode his bike with no training wheels just 2 months after turning 4. He picks up on things very fast. He learns things quickly. He is really smart, especially for his age. I have 2 other children. My second son, 2 yrs 8 months, has slight curvature of his pinkies and my third son, 18 months, has straight pinkies. My third son is like deja vu with my first son. They do everything exactly the same way. I don't believe clinodactyly has any effect on mental abilities. I think it's just hereditary.
zach on December 05, 2012:
Hello, I am a 15 year old with bent pinkies 1 worse than the other and I have no mental illness. My mother has it as well and we are both intelligent. I am also very athletic in hockey as the goalie. Also on my mother's side there is a trace of bent pinkies and none have mental illness.
Sylvie on December 01, 2012:
Hi, my baby dayghter has 2 bent pinkies. I didn't thinking anything of it when THE pediatrician pointed it out. My ex has it as well. Though, searching online i came across the connection with mental retardness. My ex isn't the brightest one. He lacks empaty and has psychopatic treats. His parents are related. He was Born with a heartcondition. Knowing now there is probably more to it i fear the chromosome results. In 6 weeks i Will know more
Roqhelle on November 27, 2012:
I am 27 years old and have lived me entire life with Bent pinkies. My mother, uncles, grandfather, and sister have them too. We are all highly intellegent people and until today I had no idea there was a name for my bent pinkies. They don't bother me except when riding a bike or playing guitar. I am happily married and they don't bother my husband either. I wasn't made fun as a child most people don't even notice unless I point it out.
ST on November 19, 2012:
I've just noticed my 18 month old daughter has clinodactyly on both hands. she has no symptoms of any syndromes, quite the opposite in fact. Has anyone with this issue tried splinting for cosmetics reasons and had any success? By and large the recommendations I've seen online suggest splinting and non-surgical procedures yield few results.
claire on October 29, 2012:
my son is 8years old and is in the process of being diagnosed with autism, he has clinodactyly on both his hands. he is also very far behind at school in every subject. no one believes its connected to his clinodactyly but i'm sure it is. i will show this blog to the hospital next time i go and see if they will believe me now.
Holly on October 17, 2012:
I am a mother of twin 19 month old girls and 1 of them have bent little pinkies....my mother was watching them tonight and she had never noticed them before! I had noticed them before but never really didn't think anything off them being different. There really isn't any difference between how she and her sister act. Should I be worried?
Dakota Frommer from Groveland, California on October 03, 2012:
My son has Clinodactyly. Although he was slow to talk and to read, he ended up earning 3 degrees from MIT. He is curious and a clever problem-solver, but not artistic or musical. His athletic pursuits have ranged from swimming to rock climbing (where a curved pinky might be useful?)
Fran on September 20, 2012:
Until now I never knew my 2 bent pinkies had a medical/scientific name! Many members of my family have bent pinkies and they were no more than a quirky genetic inheritance from my Scottish great grandmother (on my mothers side) and who knows how far back. I'm really interested in the Celtic connection here. The pinky on my left hand is much shorter (malformed?) and than my right but my children's bent pinkies are evenly sized with just a slight curve to the ring fingers of both hands.
I was prompted to find out more about this as my daughter is doing genetics in science class at school and she showed the teacher her genetic inheritence.
Kt on September 19, 2012:
My 7 year old daughters pinkies are both bent and she has always been advanced for her age and is a great artist and has never had problems with her fingers
becknutt on September 14, 2012:
Both of my daughters have ” crossed toes” the middle toe curves under the first toe. My 3 year old is very advanced. the Dr just said to watch it and make sure it doesn't cause pain or problems later in life. It doesn't affect her at all. My 7 month old was born with the exact same toes. Neither my husband nor myself have any curvature. My side of the family does have a couple of curved pinky toes.
Jammie on September 13, 2012:
Im 38 years old and I have 2 bent pinkies. My mother was always told I am very smart but always had an attention issue. I become bored in school because my mind was to aggressive for basic learning. I was the top scholar and athlete in my class. I also attended college and have been recognized as the top employee several times at my job. I have always excelled in a fast pace manner. I still like routine And Don't like dramatic change.
Barb on September 07, 2012:
My little fingers bend in only slightly, but they bend downwards from the last knuckle at a 45 degree angle. So did my mother's little fingers and all of her sisters did as well. We would put our hands down together and they all matched. All of those women were very intelligent, particularly in finance and math, great mystery readers and puzzle solvers. I have taught art for the past 38 years and am an artist. The maternal side of the family is descended from the MacGregors of Scotland. The MacGregor who immigrated in the 1600's to Virginia changed his name to McGeehee. It would be interesting to see if there is a genetic trait following that line.
Mole on August 31, 2012:
My step son is 8 and has severe learning difficulties, there is no proper diagnosis, apart from Global Development delay, he is not autistic but has some autistic traits, he is not Downs, whatever it is the geneticists think it is an anomaly or extremely rare. His little fingers are very bent.
Brian on August 15, 2012:
It's important to remember that about 50% of those with down syndrome have bent pinkies (clinodactyly), not that 50% of those with bent pinkies have down syndrome (Source:Wikipedia). In reality about 1 in 10 people have clinodactyly (Wikipedia) and 1 in 700 (691.Source: CDC) have down syndrome.
Nearly everyone in my extended family has clinodactyly and we have no known mental illness (25 people have clinodactyly out of 32). In fact, we all have extensive educations and well-rounded lives. Though clinodactyly is associated with some mental illnesses, I believe that clinodactyly is a trait that can be passed independent of mental effects.
Guest on July 03, 2012:
I am 50, can easily track the "deformity" back to great grandparent who was minor curvature, the degree of curvature increased to be more dramatic by generation, but is lessening now in my daughter & granddaughter. Our dominant heritage is native American, and no one has been on the spectrum for autism at all. In fact, all are highly intelligent & accomplished folks. Ours is not a wedge shaped bone, but a diversion at the DIP joint.
Jesu on June 30, 2012:
I have clinodactyly pinkies on both hands and I can say that I'm above average, very inquisitive. I tried to enter Mensa online, and passed their test but failed to register a CC. my IQ hovers around 128-135. I played chess on my elementary years. I play the electric guitar now and that's the only instance when the limitations of my curved pinky arises.
Jennifer on June 29, 2012:
I have 2 sons,my oldest is 6 and his pinkys on each hand is curved in but one of his pinky is more severe than the other ,my youngest was born with straight pinkys. It doesn't affect him in anyway, we tell him he is special cus he makes a heart when he puts them together ;) when he was born we didn't notice it right away till we got home and i looked over everything like new mothers do and thats when i noticed it. i took him to his doctor which he stated it was fine and that it would grow straighter eventually and even said that mine and his fathers pinkys were slightly bent which we don't see at all. After all the years i have never seen another with the same thing, until my friend had her son and he had the same identical curvation in both pinkys. We see a new doctor and I mentioned the pinkys and he actually gave me the information about clinodactyly. Which lead me here, i told my friend about it and she gave me information stating that it is a sign of autism. I am not agreeing with that finding due to my son has no signs. He is very smart,never had any problems in school except that he is a class clown. He plays basketball and is actually very good at it and has been since he was 2, he is very healthy and id say that he is like every other 6 year old. Now onto my friends child who is now 2 almost 3 does worry me, he is slow advancing in talking and is not a people person,he will hide in his room kicking the wall screaming each time i visit, she is concerned that he does have autism and i am as well. Though i don't believe it be linked to the curved pinkys. I don't think we will have have it corrected due to he loves them and it does not bother him at all with his everyday life, I love that he is the way he is and if later on he chooses to get them corrected then ill stand behind him but im positive we may never cross that day..
