Summary
Autism spectrum disorder (ASD) is a neurodevelopmental disorder that affects ~1% of the population. Progress has been made in elucidating the genetics of ASD through large-scale genome-wide association studies (GWAS) and whole-exome sequencing (WES) studies that have identified several loci associated with ASD. However, a substantial fraction of ASD status cannot be explained by genetic sequence variation. There are multiple reasons to expect that DNA methylation (DNAm) may account for part of this unexplained variation. First, part of the ASD-related genes identified via DNA sequence variatio
