Description
The University of Pittsburgh (PITT) GWAS is a SNP array dataset used to identify risk and age-at-onset genes for Alzheimer’s disease (AD). This dataset was used in the replication stage of the ADGC Naj et al. meta-analysis from 2011. It is one of the five cohorts assembled by ADGC to replicate genetic variant findings in LOAD. Provided here are the PLINK genotype files that have undergone ADGC quality control procedures, covariates formatted by ADGC to be used with the genotype data, and imputation files (.bgen format) generated using the TOPMED-r2 reference panel.
