Population-level structural variant characterization using pangenome graphs

N/A (pan-genomic structural variants)

Pangenome graph construction from high-quality long-read genomes of world populations → SV detection and cataloging at population scale → identification of new clinically actionable SVs not captured by linear references; benchmarking of existing SV callers on this new reference

Construction of a pangenome graph from high-quality long-read genomes representing world populations, for population-level structural variant (SV) characterization. The study identifies thousands of new SVs not represented in current linear reference assemblies (GRCh38, T2T-CHM13), some of which are clinically actionable. SV caller benchmarking on this new reference demonstrates that performance varies significantly by caller and SV type.

The pangenome reference is the future of long-read sequence alignment. The newly identified SVs enrich the spectrum of potential causal variants in rare diseases, particularly for families with negative exome/short-read WGS. Direct impact on labs investing in LRS pipelines with pangenome alignment.
