Identification of the novel allele HLA-A*0131N by sequence-based typing in a Chinese individual.

A novel human leukocyte antigen-A allele, officially named HLA-A*0131N allele, was found in a potential Chinese bone marrow donor when direct sequence-based typing was carried out. The novel A*0131N is identical to A*01010101 with an exception of one base substitution at position 178 (G>A) of exon 2 resulting in codon #60 changed from TGG (Trp) to TAG (stop codon).
