Kendler et al. (2011) performed an AD GWAS in a population-based sample of 2,357 EAs and 812 AAs from the Molecular Genetics of Schizophrenia (MGS2) control sample. Rather than examining association with case-control status, this study examined a quantitative AD criterion factor score. Although no GWS SNPs were identified in either sample, three genes (PITRM1, PIGG, and AKAP9) were significant in the gene-based analysis in EAs.
