Long-read whole genome sequencing (LR-WGS) technologies enhance the discovery of structural variants (SVs) and tandem repeats (TRs). Application of LR-WGS has potential to identify novel risk factors that contribute to autism spectrum disorder (ASD). We performed LR-WGS on 243 individuals from 63 ASD families and generated an integrated call set combining long- and short-read data. LR-WGS increased detection of gene-disrupting SVs and TRs by 29% and 38%, respectively, and enabled identificati...
