WebSep 16, 2024 · Author summary The translation of results from genome-wide association studies (GWAS) into polygenic risk scores (PRS) to predict disease risk or outcomes is a major aspiration in the field of statistical genetics. While there has been significant progress in this area for many complex diseases, the lack of diversity in GWAS is transferred to PRS … A typical PRS study involves testing evidence for an association between a PRS and a trait(s) in the target data. The association between PRS and outcome can be measured with standard association or goodness-of-fit metrics, such as the P value derived in testing a null hypothesis of no association, phenotypic … See more When the classic C+T method is used, the results of PRS association tests are sometimes displayed as a bar plot, where each bar corresponds to the result from … See more There is intense interest in the potential clinical utility of PRSs—to improve diagnoses, to select optimal treatment and in particular as part of preventative … See more PRSs for many traits are presently such weak proxies of true genetic liability that the phenotypic variance that they explain is often very small (R2< 0.01). … See more The central limit theorem dictates that if a PRS is based on a sum of independent variables (here, SNPs) with identical distributions, then the PRS of a sample … See more
