Identification of a novel HLA-B*15 allele (B*9552) by sequence-based typing in a Chinese donor

A novel human leukocyte antigen B allele, B*9552, has been identified by sequence-based typing in a donor of Chinese Marrow Donor Program, which has one nucleotide change at position 272 (C-->A) in exon 2 from the closest matching allele B*15010101, resulting in an amino acid substitution from Ser to Tyr at codon 91.
