Hello. I have a 6 year old son named Kaden who has mirror movements in his hands. He has done this all his life and so far he has had no difficulties that require two different hand movements at the same time. We had him tested for Klippel-Fiel Syndrome a couple of months ago and he doesn't have that, so now we're in the process of testing him for Kallman's Syndrome. Hopefully the results come back negative. These were my two main concerns as to why he does this, so my question is, are there any other syndrome's that he should be tested for, or that I should be concerned with? Everything else is normal with him, and he is where he should be in school. Im not to worried about the whole thing overall and whatever the case it makes Kaden who he is and I wouldn't want him any other way :)!!
