Abstract excerpt
Although the B70 antigen exhibits allele frequencies of 8-23% in African and American black populations, it remains poorly defined. Cloning and sequencing of cDNA encoding B70 antigens from six cell lines has identified a group of three closely related alleles: B*1503, B*1509 and B*1510, that form a subgroup of the B15 family. The sequences of these alleles and, in particular, B*1503, are close to that of the...
