## Description

The ADC2 sample set was genotyped by the Center for Applied Genomics at the Children’s Hospital of Philadelphia using the Illumina Infinium HD Human660W-Quad (Human660W-Quad_v1_A) BeadChip which captures genotype data on 657,366 genomic SNPs. The standard Alzheimer’s Disease Genetics Consortium (ADGC) quality control pipeline (Naj et al. 2011) was applied to this GWAS dataset.
