    The Relationship Between The PRO12ALA Polymorphism Of The PPAR?2 Gene And The Metabolic Syndrome In A Population Of Central Romania Diagnosed According To The Idf Criteria

    Acta Endo (Buc) 2008 4(3): 263-271 doi: 10.4183/aeb.2008.263

    Abstract
    The nuclear receptor coding PPARγ2 (PEROXISOME PROLIFERATORACTIVATED RECEPTOR-GAMMA; *601487) gene influences the lipid and carbohydrate metabolism via multiple pathways and is a candidate for the metabolic syndrome. In this paper we studied the relationship of the CCG (Pro) → GCG (Ala) polymorphism of the gene with the metabolic syndrome diagnosed according to the criteria recommended by the International Diabetes Federation (IDF) in 2005, in a population from central Romania. We have carried out a case-control study on 144 patients and 73 control subjects. Routine biochemical assays have been carried out, fasting insulinemia was measured by ELISA, and insulin sensitivity was assessed by calculating the HOMA and QUICKI indices. Genetic analysis was done by PCR followed by digestion with the restriction enzyme BstU I. The results show that the Pro12 allele had a higher frequency in the group of patients as compared to the healthy controls (76 vs. 65.7%, p<0.05). The risk for developing the metabolic syndrome in the presence of the Pro12 allele in a homozygous combination was found to be low but statistically significant (PP vs. PA + AA: OR = 1.98, CI 95% 1.04 -3.78, p = 0.046). In conclusion, in the local population, the Pro12 allele of the PPARG2 gene seems to contribute to the hereditary predisposition of the metabolic syndrome diagnosed according to the recommendations of the IDF, most likely as part of a polygenic system. Probably the absence of the protective Ala12 allele increases the risk for developing the disease.
