GW Researchers Reveal First Autism Candidate Gene that Demonstrates Sensitivity to Sex Hormones

George Washington University researcher, Dr. Valerie Hu, Professor of Biochemistry and Molecular Biology, and her team at the School of Medicine and Health Sciences, have found that male and female sex hormones regulate expression of an important gene in neuronal cell culture through a mechanism that could explain not only higher levels of testosterone observed in some individuals with autism, but also why males have a higher incidence of autism than females. 

“It is well known that males have a higher tendency for autism than females; however, this new research may, for the first time, provide a molecular explanation for why and how this happens. This is just the tip of the iceberg in terms of understanding some of the biology underlying autism, and we will continue our work to discover new ways to understand and, hopefully, to someday combat this neurodevelopmental disorder,” said Dr. Hu.
