title: Identification of a new HLA-B*40 allele, HLA-B*4081, in a Chinese individual.
abstract: A novel human leukocyte antigen (HLA)-B*40 allele, officially named B*4081, was identified during routine high-resolution sequence-based typing in a Chinese potential hematopoietic stem cell transplantation donor. The HLA-B*4081 allele shows one nucleotide difference from B*400101 in exon 2 at nucleotide position 124 where G-->C (codon 18 GGG-->CGG) resulting in a coding change, 18Gly is changed to Arg, this is a unique nucleotide change among the HLA class I alleles, suggesting a point mutation mechanism.
