Genetic variants of resistin and its plasma levels: Association with obesity and dyslipidemia related to type 2 diabetes susceptibility.

Overview

Resistin, an adipokine, is involved in obesity and Type 2 Diabetes (T2D). The current study evaluates the association between RETN polymorphisms (-638 G/A, -420C/G & -358 G/A) and the risk towards T2D. Controls and T2D patients were enrolled from Gujarat, India. Polymorphisms of RETN were genotyped by Polymerase Chain Reaction-Restriction Fragment Length Polymorphism. For the genotype-phenotype correlation analysis Fasting Blood Glucose (FBG), Body Mass Index (BMI) and plasma lipid profile were used. Plasma levels of resistin were assayed by ELISA. Our study suggests an association of RETN -420C/G polymorphism with T2D risk. The CC genotype of RETN -420C/G polymorphism was found to be associated with FBG, BMI, and total cholesterol. Plasma resistin levels were found to be significantly increased in diabetic patients as compared to controls. Our findings suggest -420C/G polymorphism of RETN as an important factor which could pose a powerful risk towards T2D susceptibility.
