Phewas and pleotropy
WebNov 17, 2024 · (b) A PheWAS begins with a genetic variant of interest and systematically analyzes many phenotypes (i.e., “phenome-wide”) for association to the genotype. PheWAS has the ability to identify pleiotropy, or the finding of multiple independent phenotypes associated with a single genetic variant. WebJun 1, 2015 · This review also highlights PheWAS as an important tool for identifying new biomarkers, elucidating the genetic architecture of complex traits, and uncovering pleiotropy. There are many directions and new methodologies for the future of PheWAS analyses, from the phenotypic data to the genetic data, and herein we also discuss some …

WebFeb 2, 2024 · Pleiotropy-robust methods and power Many of the strongest results in their analysis were driven by a single variant (e.g. the effect of telomere length on glioma risk through the TERTgene), but the precision of their overall causal effect was dramatically diminished due to the presence of substantial heterogeneity across the remaining SNPs. WebDec 20, 2024 · However, when a researcher is interested in pleiotropy (Gratten and Visscher, 2016) and therefore requires to assess if particular variants are associated across a …
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 ... WebFeb 15, 2016 · Cross-phenotype associations and pleiotropy have been identified in human studies. Phenome-wide association studies (PheWAS) are an emerging method to identify cross-phenotype associations.
