In subsequent steps we identified four more independently-associated SNPs (rs3830041, rs3129939, rs2187668, rs9277535), including a proxy (rs2187668) for the HLA-DRB1*03:01 allele ( in HapMap CEU) which has been associated with MS previously [17], [18], [19], [20], [29]. The gene discussed is HLA-DRB1; the disease is myeloid sarcoma.
