Relation of Trp64Arg polymorphism of beta 3 adrenoreceptor gene with metabolic syndrome and insulin resistance in obese women

Abstract Background and aim: Trp64Arg variant in beta 3 adrenoreceptor has been reported to be associated with increased body weight and insulin resistance. These risk factors are the ones that make up the so-called metabolic syndrome. The aim of our study was to investigate the relationship between metabolic syndrome and Trp64Arg polymorphism in the beta3 adrenoreceptor gene in obese women. Methods: A population of 531 obese women was analyzed in cross-sectional survey. A bioimpedance, blood pressure, a serial assessment of nutritional intake with 3 days written food records and biochemical analysis were performed. Genotype of beta 3 adrenoreceptor gene polymorphism (Trp64Arg) was studied. Results: Prevalence of metabolic syndrome (MS) with ATP III definition was 47.1% (250 patients) and 52.9% patients without MS (n = 281 patients). Prevalence of beta 3 genotypes was similar in patients with metabolic syndrome (87.6% wild genotype and 12.4% mutant genotype) and without metabolic syndrome (87.9% wild genotype and 12.1% mutant genotype). Insulin and HOMA levels were higher in patients with mutant genotype than wild type, in patients with and without metabolic syndrome. Conclusion: In mutant group of beta3 adrenoreceptor gene patients have higher insulin and HOMA levels than wild type group, without relation with metabolic syndrome.
