Abstract:
The distribution of HLA-B61-related alleles, B*4002-B*4006, was examined in the Japanese population by using PCR-SSO and PCR-RFLP methods. About half of the B61-positive individuals possessed B*4002 and the remaining half possessed B*4006. In addition, these two major B61 alleles were separately associated with different HLA-C alleles: B*4002 exhibited a strong linkage disequilibrium with Cw10, whereas B*4006 was strongly associated with C blank and DR9. Amino acid residues that contribute to the serologic epitopes of the B61 group and their relationships with other HLA-B locus antigens are discussed.
