Understanding Autism Project

The Understanding Autism project was devoted to understanding the factors that have led to the increase in autism prevalence over the last four decades. Since receiving the National Institutes of Health Pioneer Award, wemade significant progress in ascertaining individual and community level factors that are associated with increased risk of autism.  Specifically, among other contributions, we have found evidence that points to new understandings of the expression of risk factors, of the role of de novo mutations in increasing risk, of spatial clustering at birth and diagnosis, which points to social dynamics as underlying risks of diagnosis, and of changes to the diagnostic pathway in relation to intellectual disabilities. We are rapidly expanding our data structures, analyzing new mechanisms associated with increased risk of autism, and understanding in greater detail the developmental trajectories of persons with autism. In addition to quantitative data, the project has collected life histories from individuals who have children with autism.
