CONCLUSIONS:Many genes at the LOAD GWAS loci associate with cisSNPs, some of which are the top LOAD risk SNPs. This suggests that many LOAD GWAS variants confer risk by transcriptional regulation of genes at these loci. Dissection of this transcriptional regulation is expected to have implications in the understanding of LOAD pathophysiology.
