Twins with autism The things that stand out in their hands

cnriley45 wrote:I will try...I posted photos many years ago on a palmistry message board but I cant seem to find it, The twins are much bigger and stronger now and having their hands messed with is not something they like, but Ill try....I once read that when a couple both have a sydney line they are apt to have twins, This is true for me and my husband, and was for my friend and her spouse ...But we both have children on the autism spectrum .Her children have fragile x...Have you done any study on parents hands that have had twins?

cnriley45 wrote:Im glad you started this forum :-) ...In your study did he fragile x children have the other physical features ,big ears ,long faces, ect?.. My twins have been tested for fragile x and it came back negitive,They do not have the physical feature except they are both flat footed, My friends children all 6 have alot of the physical features...Thank you for the link I look forward to reading it

cnriley45 wrote:The reason I was asking is I was under the impression that the physical features of fragile x are quite telling ,not as obvious as downs but I have not met a whole lot of fragile x people so I was curious as to the studies you have done....I do see the flipside in the autism community where the parents say their child is autistic ,and I see the traits of fragile x in their child and wonder if they have been tested...I noticed on your diagnostics picture the index fingers are not small , I have seen the small index finger in quite a few autistic hands is this not as common in fragile x

Aha, sorry... then I did not process your info correctly (but now I do understand that only the kids of your moved friend have Fragile-x syndrome).

I have corrected my previous posts in this topic in response!

  

PS. According my experience Fragile-x syndrome is much more easy to assess from then hand than autism, though one can expect a considerable overlap regarding the hand characteristics seen in both disorders (especially when autism is combined with a mental handicap).

Earlier today I found an interesting 2000 study which e.g. reports the following 3 hand features to represent clue for Fragile-x syndrome:

"15. Soft skin over the dorsum of the head
16. Hand calluses
17. Hyperextensible metacarpophalangeal joints"

Would be interesting to hear of your autistic boys have these characteristics?

By the way, 'tactile defensiveness', 'hand biting', 'hand flapping', 'simian/Sydney line', and a 'high axial triradius' are other hand features that are mentioned inside the article. I expect to update my Fragile-x article with at least 2 new hand features in the near future.
