“The current science suggests that several genetic factors may increase the risk of autism in a complex manner. Having certain specific genetic conditions such as Fragile X Syndrome and Tuberous Sclerosis has been identified as conferring a particularly increased risk for being diagnosed with autism. Certain medications, such as valproic acid and thalidomide, when taken during pregnancy, have been linked with a higher risk of autism as well.(2) Having a sibling with autism also increases the likelihood of a child being diagnosed with autism. Parents being older at the time of pregnancy is additionally linked with greater risk of autism. “
