Webb11 apr. 2024 · Genetic risk scores. We constructed three separate genetic risk scores. The first two used PLINK version 2.0 32 with weights estimated from a meta-analysis excluding the UK Biobank: a GRS 18, using all 18 genome-wide significant index variants from the discovery analysis, as well as a GRS 559 including the 559 variants at P < 1 × 10 −4. Webb18 feb. 2024 · 1 Introduction. A polygenic risk score (PRS), sometimes called polygenic score (PGS) or genetic risk score (GRS), is an estimate of an individual’s genetic risk for some trait, obtained by aggregating and quantifying the effect of many common variants (usually defined as minor allele frequency ≥1%) in the genome, each of which can have a …
