Scientists believe that several genes are involved in the development of ASD. “There is a genetic susceptibility to ASD. This was initially determined by twin and other family studies. Although many chromosomal and gene abnormalities have been associated with symptoms of ASD, none of these are present in all affected children” (Errol, 2014). Scientists believe that some genetic problems seem to be inherited, while others happen randomly. Although genetics do not fully explain the occurrence of ASD, researchers looked at the additional environmental causes such as prenatal and perinatal factors, early toxin exposure, viral or bacterial infections, vaccinations, and autoimmune concerns. Scientists are studying how environmental factors affect certain genes. By studying how environmental factors affect genes, it provides many new ways to study how ASD develops and changes over time.
