Ok, thanks for all the input everyone. I don't think he has most of the symptoms (and some of the strange symptoms he does have like the notched teeth and shoulder dimples aren't listed as symptoms). I have a feeling there is something else going on, and it's quite possible there is a unique mutation at one of the breakpoints (chromosome 6 and 14 broke in half). I have the same chromosomal disorder and am also low tone with hypermobile joints as well. Same with my brother. So many genetic disorders cause similar symptoms, like low muscle tone. DS was already checked out by a geneticist, but I'll ask again to make sure we're not overlooking a connective tissue issue.
