The PheWAS catalog contains the PheWAS results for 3,144 single-nucleotide polymorphisms (SNPs) present in the NHGRI GWAS Catalog as of 4/17/2012 in 13,835 European-ancestry individuals from five sites of the Electronic Medical Records and Genomics (eMERGE) network. A total of 1,358 EMR-derived phenotypes were analyzed for each SNP. This PheWAS replicated 66% (51/77) of sufficiently powered prior GWAS associations, and 210/751 of all prior GWAS associations. We also identified 63 potentially pleiotropic associations with p < 4.6x10-6 (false discovery rate < 0.1); the strongest of these novel associations replicated in an independent cohort (n=7,406). The catalog contains all associations with p < 0.05 (uncorrected).
EMR-based PheWAS using ICD9 codes
These current studies using PheWAS have been performed using a custom, hierarchical grouping of International Classification of Disease, 9th edition (ICD9) codes applied to EMR data from. There are a total of 1645 PheWAS case groups (typically diseases), each with a corresponding control group. These groupings loosely follow the 3-digit (category) and section groupings defined with the ICD9 code system itself, and have been revised based on statistical co-occurrence, code frequency, and human review.
