Polymorphism of HLA-A,-B and DRB1 in Han population of Shanxi province / 中华医学遗传学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the polymorphism of HLA-A, -B, -DRB1 genes in Han population in Shanxi of China.</p><p><b>METHODS</b>Polymerase chain reaction-sequence specific primers (PCR-SSP) technique was used to identify the polymorphism of HLA-A, -B, -DRB1 genes of 7440 healthy and unrelated individuals of Han population in Shanxi, and the gene frequency distribution of HLA-A, -B, -DRB1 genes in population was compared with the results from other populations.</p><p><b>RESULTS</b>Eighteen HLA-A, forty HLA-B and thirteen HLA-DRB1 alleles were found. The frequencies of A*02, A*24, A*11, A*01, A*03, B*13, B*51, B*15, B*40, B*35, DRB1*15, DR*09, DR*12, DR*04, DR*07 alleles in Hans of Shanxi were significantly higher and displayed distinctive distribution profiles when compared with those of Caucasian and Afro-American.</p><p><b>CONCLUSION</b>The HLA-A,-B,-DRB1 distribution in Shanxi Han population shares some genetic characteristics with other Han populations in northern part of China, but it exhibits its own characteristics.</p>
