Genome Biol. 2022 Dec 27;23(1):268. doi: 10.1186/s13059-022-02837-1. ABSTRACT BACKGROUND: Genetic variants within nearly 1000 loci are known to contribute to modulation of blood lipid levels. However, the biological pathways underlying these associations are frequently unknown, limiting understanding of these findings and hindering downstream translational efforts such as drug target discovery.
