HLA-DRB1 and myeloid sarcoma: A review by Anagnostouli et al. (2018)35 concluded that while HLA‐DRB1*1501 is clearly a risk factor for both POMS and AOMS patients, the results regarding the association between HLA‐DRB1 variability and age of MS onset are conflicting: some studies describe HLA‐DRB1*1501 as being associated with an earlier onset age, whereas others claim that there is no correlation between HLA‐DRB1*1501 and age.
