ALMARZA, Johan et al. Polimorfismos del gen UCP-3 en individuos con Síndrome Metabólico del Municipio Maracaibo-Venezuela. Rev. Venez. Endocrinol. Metab. [online]. 2012, vol.10, n.2, pp.65-71. ISSN 1690-3110.

Objectives: The frequency of metabolic syndrome (MS) in adult populations is constantly increasing in Zulia State. In this study we determined the frequency of polymorphisms G304A exon 3 of the UCP-3 gene and its association with metabolic syndrome components and body composition. Methods: The sample consisted of 92 individuals (45 with diagnosis of MS, according to the criteria of the International Diabetes Federationand 47 healthy subjects). versions were analyzed by PCR-RFLP. Results: The genotype frequency of G/G and G/A was 84.45 and 15.55 respectively in the MS group with a G and A allele frequency of 0.92 and 0.08 respectively, while the genotype frequency in the control group of G/G and G/A was 97.88 and 2.12 respectively with a G and A allele frequency of 0.99 and 0.01. Significant differences were observed between genotype G/G and G/A fasting glucose values (p <0.0001), systolic blood pressure (p<0.004), triacilgicéridos (p <0.042) in patients with MS and fat percentage (p <0.04). Also observed significant differences in fat percentage values (p <0.043), VLDL-c (p <0.04), LDL-c (p <0.019) and triglycerides in females with MS. Conclusion: In the sample studied was observed apparent association between the genotype G/A UCP-3 gene with hyperglycemia, hypertension and increased systolic blood fat percentage and dyslipidemia in the particular case of female.
