One of the goals of the study is to discover how genetic variations in young people with ASD are related to brain changes that lead to clinical symptoms of the disorder, such as impaired social interaction and repetitive behaviors.
“If you think about it, in between genes and clinical symptoms [of ASD] are changes in brain development,” says Lainhart. “Genes first impact brain development, and as a result of changes in how the brain develops, there are clinical manifestations of what we recognize as ASD.”
