About The Study: The findings of this study including more than 1 million Swedish children suggest that the degree of phenotypic variation attributable to genetic differences (heritability) differs between males and females, indicating that some of the underlying causes of the condition may differ between the two sexes. The skewed sex ratio in autism spectrum disorder may be partly explained by differences in genetic variance between the sexes.
