In total, 18229 genes were identified in the IGAP stage 1 GWAS dataset by MAGMA, including all of the 39 GWAS risk genes in AD except INPP5D. Sixty seven MAGMA genes passed BF.pval < 0.05, including 17 AD risk genes, and 15 AD-DEGs and 20 MCI-DEGs in blood (Table 3). Here, INPP5D is linked to Alzheimer disease.
