We tested for presence/absence of the DPB1*03:01 allele in 422 Australian MS cases using a combination of sequence specific priming and sequence based typing, and found a correlation with rs9277535 (, Table S6): all but two individuals carrying the DPB1*03:01 allele also carry the rs9277535G allele. This evidence concerns the gene HLA-DPB1 and myeloid sarcoma.
