Study on the association between the HLA-DRB1 alleles and type 2 diabetes in Yi nationality of Yunnan / 中华医学遗传学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the association between the polymorphism of HLA-DRB1 alleles and type 2 diabetes mellitus in Yi nationality of Yunnan.</p><p><b>METHODS</b>Polymerase chain reaction-sequence specific primers (PCR-SSP) genotyping method was conducted in 79 patients with type 2 diabetes mellitus and 47 ethnically matched controls in Yi Nationality Autonomous Prefecture, Chuxiong.</p><p><b>RESULTS</b>HLA-DR7 and DR11 allele frequencies in type 2 diabetic mellitus patients were significantly higher than those in non-diabetic control subjects respectively(P is 0.009, RR is 8.329;P is 0.029, RR is 7.734).</p><p><b>CONCLUSION</b>DR7 and DR11 alleles are probably susceptible genes of type 2 diabetes mellitus in Yunnan Yi nationality.</p>
