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].

While any of the novel PheWAS associations indicate potential pleiotropy as all of the SNPs of this study have previously reported genome-wide associations, within our study, we found 13 SNPs with more than one significant PheWAS phenotype class (Table 4 and Fig. 4). While the majority of these were … WebJan 29, 2024 · Compared to GWAS, one promising advantage of PheWAS is to examine pleiotropy by measuring genetic associations of one variant with thousands of diseases or phenotypes simultaneously. Variants demonstrating pleiotropy may confer tissue-specific effects on multiple genes [ 77 ], some of which could occur on different chromosomes …
