Abstract

Complex structural variants (cxSVs) are genomic rearrangements comprising multiple structural variants, typically involving three or more breakpoint junctions. They contribute to human genomic variation and can cause Mendelian disease, however they are not typically considered during genetic testing. We investigated the role of cxSVs in Mendelian disease using short-read whole genome sequencing (WGS) data from 1,324 individuals with neurodevelopmental or retinal disorders from the NIHR BioResource project. We identified four cases of individuals with a cxSV affecting Mendelian disease-associated genes. We used nanopore sequencing to resolve the mechanism of one of the variants. Our results show cxSVs are an important, although rare cause of Mendelian disease, and we therefore recommend their consideration during research and clinical investigations.
