There is no single cause of autism spectrum disorder. This still remains controversial and continues to be studied. But groundbreaking new research indicates that environmental factors may also be important in the development of autism. A loss-of-function variant in SUV39H2 identified in autism-spectrum disorder causes altered H3K9 trimethylation and dysregulation of protocadherin β-cluster genes in the developing brain. It is becoming apparent that: Autism is most probably caused by multiple factors interacting in complex ways (i.e. Autism's theory of causation is incomplete.
