For example, with regard to the HLA-DRB1 classical alleles, Asian SLE patients were characterized by possession of more copies of HLA-DRB1*09:01 and HLA-DRB1*15:01 (and its correlated HLA-DQB1*06:02) than healthy individuals [75,77,92]. The gene discussed is HLA-DRB1; the disease is systemic lupus erythematosus.
