Proximity-mapped whole-genome sequencing for characterization of repeat expansions and variants in highly homologous genomic regions

Background: Short-read whole-genome sequencing (sWGS) has limitations in characterizing tandem-repeat expansions and variants in highly homologous or pseudogene-associated regions. Long-read sequencing can address some of these challenges but often benefits from high-molecular-weight DNA. TruPath Genome incorporates spatial proximity information into a short-read sequencing framework. This study evaluated its performance in characterizing selected complex genomic variants using archived clinical DNA specimens. Methods: Ten archived peripheral blood DNA specimens were analyzed, comprising seven
