“Many brain disorders have sex-biased prevalence. Why is it so challenging to find sex-differential genomic signals in brain?”

 

Genetic variants contribute to risk for neurodevelopmental disorders, many of which show sex differences in their prevalence or presentation. This suggests a potential role for sex-differential biology in modulating the impact of genetic and other risk factors, such that one sex is sensitized and/or the other is protected from risk. One particularly striking example is autism spectrum disorder (ASD): Males are diagnosed with ASD at least three times more frequently than females, and this skew is one of the most consistent, yet mechanistically unexplained, features of ASD.

The aim of my research is to understand the key neurobiological mechanisms involved in the etiology of ASD and other neurodevelopmental disorders, including genetic and developmental processes, with a focus on the role of sex-differential biology in modulating risk. Genome-scale analyses are especially powerful for unbiased discovery, and so my lab uses genome-wide genetics, functional genomics, and bioinformatics approaches (e.g. RNA-seq, single cell analyses, eQTLs) in human tissue and model systems to identify and characterize the mechanisms involved in sex-differential and disorder-associated neurobiology. The long-term goal of this research program is to uncover fundamental etiological pathways in both sexes that will facilitate treatment development and benefit affected individuals and their families.
