AI Insight
A gene called ZFX located on the X chromosome has been found to exert significant regulatory control over a network of genes associated with autism spectrum disorder. This discovery may help explain the lower prevalence of autism in females, who possess two copies of the X chromosome compared to one in males. The gene appears to provide a protective effect by influencing the expression of multiple autism-related genes.
Why it matters
This finding could help explain the long-observed sex difference in autism diagnosis rates, where males are diagnosed approximately four times more frequently than females. Understanding this protective mechanism may lead to new therapeutic approaches for autism and improved diagnostic criteria that account for sex-based biological differences.
