WebPhenome-Wide Association Studies (PheWAS) compare EMR phenotypes with a single dependent variable, historically a genetic marker. The tools described on this page are specifically for the study of phenotypes derived from International Classification of Disease (ICD) codes. They employ a mapping from ICD-9 and ICD-10 codes to 1,866 hierarchical ... WebPhenome Wide Association Studies. Phenome-wide association studies (PheWAS) analyze many phenotypes compared to a single genetic variant (or other attribute). This method was originally described using electronic medical record (EMR) data from EMR-linked in the Vanderbilt DNA biobank, BioVU, but can also be applied to other richly phenotyped sets.
