Research by Topic: Testosterone
Podcast: What is true for males is not true for females
Published February 26, 2018On this week’s podcast, Dr. Alycia Halladay focuses in on the Extreme Male Brain Theory of Autism. Amazingly, fetal testosterone levels are reflected in the length of the 2nd and 4th fingers and can be measured as a reflection of testosterone levels during pregnancy. But what may be true for one sex, may not be […]

Sex Differences in Autism Spectrum Disorders
Published February 13, 2013 in Current Opinion in NeurologyA 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, […]

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 […]
