Jan 6, 2018 · Autism spectrum disorder has no single known cause. Given the complexity of the disorder, and the fact that symptoms and severity vary, there are probably many causes. Both genetics and environment may play a role.
Aug 20, 2021 · Autism spectrum disorders (ASD) are a group of neurodevelopmental diseases. The cause of ASD is unknown, but several genetic and non-genetic risk factors have been characterized that, alone or in combination, are implicated in the development of ASD.

About. What causes autism? Scientists don't know exactly what causes autism spectrum disorder (ASD). Autism was first described in the 1940s, but very little was known about it until the last few decades. Even today, there is a great deal that we don't know about autism.
Prenatal viral infection has been called the principal non-genetic cause of autism. Prenatal exposure to rubella or cytomegalovirus activates the mother's immune response and may greatly increase the risk for autism in mice. Congenital rubella syndrome is the most convincing environmental cause of autism.
Jul 4, 2011 · A new Stanford University School of Medicine study of twins suggests that non-genetic factors play an unexpectedly large role in determining autism risk, turning upside down recent assumptions about the cause of this common, disabling developmental disorder.
Aug 20, 2019 · Genetic modifiers in autism spectrum disorder. Autism is estimated to be 40–80% heritable. However, both genetic and non-genetic factors modulate the penetrance of risk genes, resulting in a highly heterogeneous disease phenotype for similar pathogenic variants.
