A possible pathogenic mutation in the β3-adrenergic receptor gene (Trp64Arg) has been reported to be associated with Diabetes type 2, Non-insulin-dependent diabetes mellitus (NIDDM), in different group ethnic subjects. Since that, several mutations of candidate genes have been reported associated with Diabetes type 2 in Peruvians and subjects from other nationalities. It was investigated the frequency of polymorphism Trp64Arg in the β3-adrenergic receptor gene, biochemical and anthropometric measurements of 72 type 2 diabetic subjects, and 21 as control group, both genders, aged between 30 and 70 years all of them of the province Sullana (North of Perú) as this city as high prevalence of Type 2 Diabetes in the country. The laboratory study was conducted in: Peruvian Institute of Molecular Biology (IPBM), the Laboratory of Molecular Biology of Faculty of Veterinary Medicine and Faculty of Pharmacy and Biochemistry – Universidad Nacional Mayor de San Marcos. The analysis of the results was performed using the SPSS 15 version found that the frequencies of the genotypes of β3-adrenergic receptor gene in the study population was: 61.1% (44) Trp64Trp, 27.8% (20) Trp64Arg and 11.1% (8) Arg64Arg for diabetics, and: 57.1% (12) Trp64Trp, 14.3% (3) Trp64Arg and 28.6% (6) Arg64Arg to controls. Furthermore, we found the following allelic frequencies in the β3-adrenergic receptor gene in diabetic patients and controls for the Trp allele, 75% and 64.3% for Arg: 25.0% and 35.7% respectively, which suggests that the frequency allelic to the mutation (Arg) was slightly lower but not statistically significant (p same to 0.088). Diabetics were found with bad glycemic metabolic control and hyperglycemia. In applying the Student t test in diabetics and controls was observed that only the glycosylated Hemoglobin (Hb-G) had statistical significance (p same to 0.039), which could be associated with the Trp64Arg polymorphism. In the analysis of genotypes versus BMI, dyslipidemia and glycemic metabolic control in subject controls was significant difference for the BMI parameter in the different genotypes, but not in type 2 Diabetes. Of risk analysis found that Odds ratios in the total study subjects (diabetic controls more) Trp64Arg genotype achieved a degree of risk factor for overweight, dyslipidemia, and bad glycemic metabolic control, and that Arg64Arg genotype is a risk factor related with overweight and diabetes, but none had significant statistical difference. We conclude that the polymorphism under this study is important, but neither the only, nor the most decisive factor to develop type 2 Diabetes.
