HLA-DQB1 and myeloid sarcoma: Although HLA-DQB1*06:02 did not pass quality control thresholds in their study, a similar pattern for HLA-DRB1*15:01 was identified by Chi et al. who determined that risk of MS conferred by the EUR HLA-DRB1*15:01 allele was three times higher compared to the AFR HLA-DRB1*15:01 allele.
