Six RA GWAS manuscripts were identified by querying the HuGE Navigator database for "rheumatoid arthritis." Together, these studies document twenty-eight SNPs that are significantly associated with RA, p < 10^-6. Of these twenty-eight SNPs, seventeen (or their proxies) were present in our AD GWAS and evaluated further for their association with AD.
