## Description

The 90+ sample set was genotyped at the Children’s Hospital of Philadelphia using the Illumina Infinium GSAMD-24v2-0_20024620_A1 BeadChip which captures genotype data on 759,993 genomic SNPs. The standard Alzheimer’s Disease Genetics Consortium (ADGC) quality control pipeline (Naj et al. 2011) was applied to this GWAS dataset.
