Is autism a nurture or nature?

Is autism environmental or genetic?

Autism spectrum disorder has both genetic and environmental origins. Research into the genetic origins of ASD has consistently implicated common and rare inherited variation (heritability). However, evidence shows that there are other, noninherited, genetic influences that could be associated with variation in a trait.
