Interestingly, the rs1964995 SNP located between HLA-DRB9 and HLA-DRB5, a risk SNP only in AAs in our study, was protective in a Swedish cohort with non-Lofgren sarcoidosis GWAS [47], but increased the risk of rheumatoid arthritis in ADs, but not in EDs [48]. The gene discussed is HLA-DRB5; the disease is rheumatoid arthritis.
