The prevalence of the MetS was 23%.In a marker-by-marker analysis, the ADRB2 rs180088 (OR 1.22, 95% CI 1.01-1.48) and PAI1 r</span>s1799768 (OR 1.05, 95% CI 1.01-1.10) were associated with an increased MetS risk, whereas the C5 rs17611 (OR 0.95, 95% CI 0.91-1.00) and the CTLA4 rs5742909 (OR 0.91, 95% CI 0.84-0.99) were associated with a decreased risk.
DNA was extracted from the whole blood of 192 natural postmenopausal women (40 to 65 years) screened for the METS and tested for three gene SNPs related to obesity: the fat mass obesity (FTO: rs9939609) and the methylenetetrahydrofolate reductase (MTHFR: C677T and A1298C).
