Abstract

The aim of this study was to investigate the relatively frequencies of alleles in the HLA-C04:01:01G group and to analyze their relations with HLA-A and -B loci. DNA samples previously typed as HLA-C04:01:01G were sequentially selected. The sequences for exon 2 to 7 of the HLA-C locus were analyzed by polymerase chain reaction sequence-based typing(PCR-SBT). The HLA-A, -B, -DRB1 and -DQB1 loci were genotyped using PCR-SBT method. The results showed that 178 samples (94.2%) and 11 samples (5.8%) were assigned as HLA-C04:01:01 and HLA-C04:82 respectively among 189 samples previously typed as HLA-C04:01:01G. 72 haplotypes associated with HLA-C04:01:01 and C04:82 were found, in which the frequencies of 26 haplotypes were over 0.0050. HLA-C04:01:01 was strongly related with A02:03, A02:07, A11:01, A33:03, B13:01, B15:01, B15:05, B15:27, B40:01, B54:01 alleles, while HLA-C04:82 was related with B40:01. It is concluded that HLA-C04:01:01 and HLA-C04:82 alleles were confirmed in the HLA-C*04:01:01G group, which should be discriminated by the routine HLA genotyping.
