Objective: To investigate the gene polymorphism of human leukocyte antigen (HLA)-A, B, DRB1 loci in the population of Beijing region, and research on the application feasibility of polymerase chain reaction sequence-based typing (PCR-SBT) method.
Methods: PCR-SBT method was applied to determine HLA- A, B, DRB1 genotypes of 618 unrelated healthy individuals of Beijing region.
Results: A total of 84 different alleles and 199 genotypes of HLA-A, 143 alleles and 366 genotypes of HLA-B, 122 alleles and 286 genotypes of HLA-DRB1 were detected.
Conclusion: The results showed the characteristics of HLA-A, B, DRB1 distributions, and provided more comprehensive and accurate gene data that may serve as normal reference values for all of Beijing people.
