Phewas and pleotropy
Webwide association studies (PheWAS), where the association of each genetic variant with all phenotypes in a dataset is tested [34–37]. One challenge of the PheWAS approach is the high multiple-testing burden that grows as the number of traits and variants tested increases [9]. Although this can be partly circumvented by performing targeted ... WebDec 2, 2024 · Our PheWAS uncovered novel associations and replicated previously reported relationships between schizophrenia, bipolar disorder, and major depression PRS and a range of clinical traits and outcomes, highlighting the potential of PRS for disentangling biological and mediated pleiotropy.

WebJul 28, 2015 · In studies of genetic manipulations in which the engineered changes are precise, the term pleiotropy tends to be restricted to individual genes or mutations within genes, while in population studies in both model organisms and humans, loci containing more than one gene can be called pleiotropic.
