Genetic etiologies of autism: Unpacking pathogenic mechanisms and characteristics

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review

Abstract

This chapter provides an overview of historical and modern approaches for understanding genetic causes of autism spectrum disorder (ASD), thought to account for ≥  10%-30% of ASD. Innovations in modern genome and exome approaches and targeted sequencing within recent decades have implicated over 100 genes and genomic regions in ASD. We showcase recent advances from a genetics-first approach to characterize unique phenotypes of genetic ASD subgroups (e.g., de novo genetic variants, ASD-related syndromes). In addition, we describe future directions of ASD genetics, including the growing consensus of polygenic risk, relevance of noncoding regions, and rare inherited variants.
