The International Genomics of Alzheimer's Project (IGAP) is releasing the summary results data from the 2013 meta-analysis of Genome-wide Association (GWA) data in Alzheimer's disease, in order to enable other researchers to examine particular variants or loci for their evidence of association. The files include p-values and direction of effect at over 7 million directly genotyped or imputed single nucleotide polymorphisms (SNPs). To prevent the possibility of identification of individuals from these summary results, allele frequency data are not released.
"Two dataset are provided. The first one corresponds to the meta-analysis results obtained in stage 1 including genotyped and imputed data (7,055,881 single nucleotide polymorphisms, 1000G phase 1 alpha imputation, Build 37, Assembly Hg19) of 17,008 Alzheimer's disease cases and 37,154 controls. The second one corresponds to the meta-analysis results of the 11,632 SNPs that were genotyped and tested for association in an independent set of 8,572 Alzheimer's disease cases and 11,312 controls with the combined stage1/stage2 P-values."
