boys 4 times more likely to get autism
Sunday, March 29th, 2009Below is a video discussing the genetics of autism. If one twin has autism, an identical twin has a 90% chance of having autism or an autistic spectrum disorder. That is a very high heritability rate. Boys are 3 to 4 times more likely to have autism than girls. No one gene is implicated; it appears to be combinations of genes that are involved.
