Association of Gly82Ser polymorphism of receptor for advanced glycation end products gene in a type 2 diabetic Chinese population / 南方医科大学学报

ABSTRACT

<p><b>OBJECTIVE</b>To assess the distribution frequency of Gly82Ser polymorphism of receptor for advanced glycation end products (RAGR) gene and investigate its association with type 2 diabetic Chinese patients.</p><p><b>METHODS</b>The allele frequencies and genotype distribution of Gly82Ser polymorphism of RAGE gene were compared in a case-control study of 194 type 2 diabetic and 546 non-diabetic subjects. PCR-restriction fragment length polymorphism (PCR-RFLP) was used for detection of the genotype variants.</p><p><b>RESULTS</b>In general Chinese population and type 2 diabetic Chinese patients, the most frequent genotype and allele of RAGR gene Gly82Ser polymorphism were genotype GG and allele G, whose frequency distribution were significantly higher than those in other countries (P<0.01). No significantly difference in the genotype frequencies or allele frequencies of Gly82Ser polymorphism were found between the diabetic patients and non-diabetic subjects (P>0.05).</p><p><b>CONCLUSION</b>Gly82Ser polymorphism of RAGE gene does not demonstrate any association with type 2 diabetes in Chinese patients, but high genotype and allele frequencies of Gly82Ser polymorphism occur in Chinese population and type 2 diabetic Chinese patients.</p>
