Sex Differences in Autism Spectrum Disorders

Published February 13, 2013 in Current Opinion in Neurology

A review of current research shows that ASD affects females less frequently than males and suggests this difference may be due to several sex-differential genetic and hormonal factors.

Researchers Reveal First Autism Candidate Gene That Demonstrates Sensitivity to Sex Hormones

Published March 1, 2011 in Journal of Molecular Psychiatry, Hu et al.

George Washington University researchers 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. The gene, RORA, […]

Researchers Reveal First Autism Candidate Gene That Demonstrates Sensitivity to Sex Hormones

Published February 17, 2011 in Science Daily

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.

Linkage, Association, and Gene Expression Analyses Identify CNTNAP2 as an Autism-Susceptibility Gene

Published January 1, 2008 in American Journal of Human Genetics, Alarcon, Abrahams, et al.

Autism is a genetically complex neurodevelopmental syndrome in which language deficits are a core feature. We describe results from two complimentary approaches used to identify risk variants on chromosome 7 that likely contribute to the etiology of autism. A two-stage association study tested 2758 SNPs across a 10 Mb 7q35 language-related autism QTL in AGRE […]
