FERNANDEZ, Erika et al. Pro12Ala polymorphism of the PPAR-g2 gene and the metabolic syndrome: Preliminary study. Acta bioquím. clín. latinoam. [online]. 2009, vol.43, n.1, pp.3-9. ISSN 0325-2957.

The aim of this paper was to determine the prevalence of the polymorphism pro12ala in non-related individuals with metabolic syndrome from Maracaibo-Venezuela. Fifty subjects (22 with metabolic syndrome and 28 without metabolic syndrome) between 22 to 58 years of age were selected. For each individual, biochemical, nutritious, and clinical evaluations were carried out. PCR and restriction-fragment length polymorphism enzyme digestion were used to analyze the Pro12Ala sequence variant of the PPAR gene. The distribution of the Ala allele was 13.6% in the individuals with metabolic syndro- and 32.14% in the group without metabolic syndrome. The frequency distributions of the PPAR gamma sequence variants were 0.12 for Ala variant and 0.88 for Pro. The subjects with the metabolic syndrome and carriers of the Ala 12 allele had lower concentration of triglycerides and higher HDL-C. It can be concluded that the Ala12 allele in individuals with metabolic syndrome had a protective effect on the lipid profile.
