Analysis of HLA-A, B local haplotype among Han population in Northwest China / 西安交通大学学报(医学版)

ABSTRACT

Objective To analyze the HLA-A, B local haplotype frequencies of Han population in Northwest China. Methods The results of HLA-A, B local polymorphism were obtained by using the PCR-sequence specific oligonucleotide probes (SSOP) reverse dot blot. Haplotype was inferred by the heredity law of HLA. Results The high haplotype frequencies were A02-B46, A30-B13, A02-B40. Linkage disequilibrium parameters of 11 haplotypes had significant differences. Conclusion The HLA-A, B local haplotype frequencies of Han population in Northwest China differ from those of Han population in other areas. The haplotypes A30-B13, A01-B37 and A32-B44 present significant linkage disequilibrium.
