## Description

The PITT GWAS sample set was genotyped using the Illumina HumanOmni1-Quad BeadChip which captures genotype data on 1,016,423 genomic SNPs. The standard Alzheimer’s Disease Genetics Consortium (ADGC) quality control pipeline ([Naj et al. 2011)](https://pubmed.ncbi.nlm.nih.gov/21460841/)
 was applied to this GWAS dataset. The final QC’d dataset is on GRCh38.
