In the Welcome Trust Case Control Consortium (WTCCC) dataset, the odds ratio (OR) for an association the full HLA-DRB1*15:01~HLA-DQB1*06:02~a1 haplotype with MS was 3.28 (p<<10−300) and similar disease associations for portions of this haplotype have been consistently reported in many other MS populations across Northern Europe and North America [11, 15–24]. The gene discussed is HLA-DRB1; the disease is myeloid sarcoma.
