Identification of HLA-A*02-B*46 haplotype allele variant in Guangdong Han populations on the basis of PCR-SBT.

Background The HLA-A*02-B*46 haplotype is one of most frequent haplotypes among Guangdong Han populations. To explore the characteristics of the HLA-A*02-B*46 haplotype in Guangdong Han populations, the genetic polymorphism of HLA-A*02-B*46 haplotype was analysed by PCR-SBT in our study.
