   Can genetics cause autism?

   • Autism is complex, and no two autistic people are the same. Because of this, researchers believe there are probably many causes of autism, including genetic and environmental factors. So far, some evidence suggests that changes (aka mutations) in a person’s genes could cause autism.

   Can a gene change cause autism?

   • Changes in certain genes or your genome increase the risk that a child will develop autism. If a parent carries one or more of these gene changes, they may get passed to a child (even if the parent does not have autism). For some people, a high risk for ASD can be associated with a genetic disorder, such as Rett syndrome or fragile X syndrome.

   Do genetic factors contribute to autism susceptibility?

   • Genetic factors play a role in ASD susceptibility, with siblings of patients with ASD carrying an increased risk of diagnosis when compared to population norms, and a much higher, although not absolute, concordance of autism diagnosis in monozygotic twins ( 42 - 44 ).
