Characterization of a new HLA-C allele in a Chinese family by sequence-based typing: HLA-Cw*0348.
The novel human leukocyte antigen (HLA)-Cw*0348 allele was identified by sequence-based typing in a Chinese family. This allele shows that the sequences of exons 1-3 of HLA-Cw*0348 are identical to those of HLA-Cw*030401 except for a nucleotide substitution that changes CCG to CTG at codon 57, resulting in an amino acid change from Pro to Leu in the protein, and this is a unique nucleotide change among the HLA-C alleles, suggesting a point mutation mechanism. The extended haplotype carrying the new allele was deduced from the family group typing and defined as A*110101, B*1301, Cw*0348, DRB1*0405, and DQB1*0402.
