It does not have any proof that if a pregnant woman takes any drugs for inducing labor causes autism in children. However, autism is a genetic disorder that causes abnormalities in the structure of the brain. A pattern of autism or related disabilities appears to exist in many families, further supporting the theory that the disorder has a genetic basis. While no gene has been identified as causing autism, researchers are searching for irregular genetic code segments that may have been inherited by children with autism. Some children also appear to be born with a susceptibility to autism, but researchers have not yet identified a single "trigger" that causes the development of autism.
Other researchers are examining the potential for an unstable gene cluster to interfere with brain development under certain conditions, resulting in autism. Other researchers are also investigating issues during pregnancy or delivery, as well as environmental factors such as viral infections, metabolic imbalances, and chemical exposure.
