It's actually not likely at all. We have had tests for Fragile X syndrome, and a full chromosome count. They came back fine. It's like a needle in a haystack... They don't even know where to start looking- if none of the searchable conditions come up positive.
I'd like to have a support group- yanno? People who have been through what I am going through... I'd like prognosis. We have none, no insight at all. If I could afford it, I'd just pay for tests, but it's so hard for the RCH to even suggest what we test for next! There are so many parts on the chromosomes themselves that could be the culprit
