Brian O'Roak, Ph.D.
Assistant Professor of Molecular and Medical GeneticsWhat’s been the most interesting development in your area in the last two years?
We study the genetic basis of complex neurodevelopmental disorders, such as autism. In just the past few years, we have gone from virtually no high-confidence risk genes for autism to over 50 utilizing innovative cohorts and high-throughput sequencing! (Learn more in this webinar I recently gave.) Importantly, while these genes are each disrupted in only 0.1-1 percent of individuals with autism, they are “common” enough to study shared characteristics and develop targeted treatments. Already we have found many of these new risk genes, when disrupted, lead to recognizable autism “subtypes” with shared (but sometimes subtle) physical characteristics and common co-occurring problems. This is particularly exciting as these features may help kids get help earlier. Despite this complexity, many of these new risk genes are falling into a handful of common biological pathways/mechanisms. This makes me hopeful about the development of common therapeutic targets that can be matched to one’s personal genetic profile. Read more
