A new study has shed light on the complex mechanisms behind the sex differences observed in autism.
The research suggests that increased dosage of a gene known as Ube3a can influence autism-related traits in a manner that differs between males and females.
By examining mice with extra copies of this gene, researchers found significant sex-specific effects on brain connectivity and behavior.
In the prefrontal cortex, many autism-associated genes exhibited dysregulated expression in a sex-dependent manner.
Some genes were upregulated in male Ube3a2X mice but downregulated in females.
This differential gene expression was particularly evident in genes located on the X chromosome and those influenced by sex steroid hormones.
