Complete sequence analysis of the A*1103 allele.

Here we report the full-length sequence of a novel A*11 variant. The variant was identified by ARMS-PCR and serology, the sequence was confirmed by cloning and subsequent sequencing. This variant, A*1103, found in a family of oriental origin, resembles the A*1101 sequence in exon 2 but differs in exon 3 with regard to codons 151 and 152.

HLA-B POT: a new HLA-antigen within the B7-cross reactive group.

In this report, a new HLA-B locus antigen is described (tentatively called POT). The antigen has been identified with antisera against the antigens that belong to the B7-cross reacting group. In a collaborative study, based on exchange of cells and sera, it was confirmed by population and family studies that the antigen is distinct from B7, Bw42 or Bw73 and is associated with Bw6.
