Video Poster: Accurate, comprehensive variant calling in difficult-to-map genes using HiFi reads

Introduction: Around 5% (1,168) of protein-coding genes in the human genome contain an exon that is difficult to map with typical next-generation sequencing (NGS) read lengths due to homologous pseudogenes or segmental duplications. Among the difficult-to-map genes are 193 with known medical relevance, including CYP2D6, GBA, SMN1/2, and VWF. Long-read DNA sequencing provides increased mappability, accessing many of the difficult-to-map regions by connecting the homologous exon to neighboring unique sequence. Until recently, the read-level accuracy of long-read sequencing had made it challenging to accurately call small variants. The recently developed HiFi reads from the PacBio Sequel II System provide both…
