Significant differences were observed for both SNPs when MS patients were stratified by the well-known susceptibility factor HLA-DRB1*15∶01 (MS 1501+ vs. Controls: GG vs. AG+AA: p = 0.02, OR = 1.50 and p = 0.001, OR = 1.60, for SNP1 and SNP2 respectively). Here, HLA-DRB1 is linked to myeloid sarcoma.
