Abstract excerpt
The generalizability of polygenic scores (PGS) remains a major hurdle in the pursuit of equitable genomic medicine. Differences in disease prevalence across groups, potentially including social strata, influence the relationship between PGS and risk. Here we quantified the magnitude of PGS-by-context (PGS×C) interactions for seven human diseases and pairs of 75 contexts in the UK Biobank (n = 408,801). Across...
