WebCausal investigations in genetics have evolved from agnostic discovery in genome-wide association studies (GWAS) to functional annotation1 and instrumental variable-informed inference (ie, mendelian randomisation)2. In the past decade, big data resources, such as the UK Biobank, have prompted a return to broader discovery through phenome-wide … WebJun 29, 2024 · As sample sizes in large GWAS/PheWAS biobank studies, e.g., for COVID-19 research [4, have grown to millions of GWAS samples and GWAS data sets of this size are likely to be used more frequently in the future, the efficiency and ease of execution of BIGwas with a single command will become an important criterion for conducting … harley zhong
From GWAS to PheWAS: the search for causality in …
WebIn this study, we used information from 337,484 UK Biobank participants and performed PheWAS using schizophrenia genetic risk score on 1135 disease outcomes. Signals that passed the false discovery rate threshold were further analyzed for evidence on the causality of the association. ...

If c () (default) then returns all batches. … In genetics and genetic epidemiology, a phenome-wide association study, abbreviated PheWAS, is a study design in which the association between single-nucleotide polymorphisms or other types of DNA variants is tested across a large number of different phenotypes. The aim of PheWAS … See more PheWAS initially started from the growing use of EMR (electronic medical record) for clinical practice and patient care. One of the main components of EMR system is the International Classification of Disease version 9-CM ( See more • Website listing catalogs of PheWASs See more Pleiotropy Study One of the main advantages of the PheWAS study is its potential to identify genomic variants with pleiotropic properties. Understanding … See more Despite the promising potentials, PheWAS has some potential limitations: • Statistical limitation: Bonferroni correction is potentially not addressing the entirety of the dataset (it may be prohibitively conservative). • ICD9-notation limitation: not every phenotype … See more harley youngstown
