Identification of the novel allele HLA-DRB1*1137 which probably originated from DRB1*11011: implications for mismatch with its ancestor allele at bone marrow transplantation.
Polymorphism of human HLA-DRB1 antigens generated by genetic exchange between DR2 (DRB1*15011) and DR6 (DRB1*1405) alleles: a novel DRB1 allele (DRB1*1437) identified in a Paiwan tribe member of Taiwan.
