Abstract
According to the CDC, males are four times more likely to be diagnosed with autism than females. New studies have shown that girls need a higher burden of genetic mutation to be diagnosed with autism than males. These findings are leading researchers to a new avenue of investigation called the female protective effect. This theory holds that even when females carry mutations in autism-linked genes, the effect of the mutations is prevented when the level of genetic disruption is low. Understanding the biology behind this protective effect and studying females independently from males could lead to major advancements in the prevention and treatment of ASD in both males and females.
