However, with the height dataset and EUR plink files, I am The ability to predict disease risk accurately is a principal aim of modern precision medicine. On this page, you will compute PRS using the popular genetic analyses tool plink - while plink is not a dedicated PRS software, you can perform every required steps of the C+T approach with plink. file. csv file into the format the PLINK 2 --score command expects. In the pics you can see how my summary stats and my target data look like. ] [allele col. If the GWAS summary statistics file provide SNP effects (BETA), use them directly in PLINK --score to compute PRS. It is designed to efficiently handle large datasets and A polygenic risk score (PRS) is genetic score which quantifies an individual's polygenic contribution to a trait. It is assuming you are working with systems similar to the IEU in bristol and have The equation used by the PRSKB for calculating polygenic risk scores is the same one used by PLINK and is comparable to the 'average' score option used by PRSice-2.
