I too believe that autism is mainly a genetic thing..maybe then triggered by a vaccination or a virus. My son is autistic and he is being tested (actually today was tested) for Fragile X as a cause. 14% of autistic males are KNOWN to have Fragile X, and that is just the KNOWN ones. I am researching too and would be interested in any other tests you think should be done on our son (Josiah is 4; adopted in November with his twin sister who is normal). ~~Anna
