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

ABSTRACT:

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.

Findings

Among 88 samples with the homozygotes for HLA-A*02-B*46 in the low resolution, 4 different alleles for A*02 (A*0201, A*0203, A*0206, A*0207) and 1 allele for B*46 (B*4601) were identified by PCR-SBT. Among them, the A*0207 allele was the predominant allele. Inversely, among the samples with HLA-A*2-B*46(-), six alleles were detected for A*02 (A*020101, A*0203, A*0205, A*0206 and A*0207), and the A*0201 allele was predominant. On the other hand, the HLA-A*02-B*46 haplotype presented
