Abstract :Objective: Dyslipidemia and metabolic syndrome (MetS) are complex diseases affected by environmental factors such as lifestyle and genetic predisposition. The genes encoding peroxisome proliferator-activated receptor-gamma (PPARG) and alpha (PPARA) are crucial in the development of dyslipidemia and MetS. We aimed to investigate the relation of these genes with dyslipidemia and MetS in the Turkish adult population. Materials and Methods: The Turkish Adult Risk Factor (TARF-TEKHARF) cohort was randomly selected, and a cross-sectional analysis was performed. The PPARA rs1800206 C>G genotypes were determined in a sample of 339 unrelated Turkish adults by a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and 12% polyacrylamide gel electrophoresis (PAGE) methods. The PPARG rs1801282 C>G genotypes were determined in a sample of 436 unrelated Turkish adults by a PCR-RFLP method. Results: Both single nucleotide polymorphisms (SNPs) minor alleles were related to a risk of dyslipidemia. Logistic regression analysis showed a significantly increased risk for dyslipidemia in G allele carriers of rs1800206 C>G (Odds Ratio (OR)= 3.26; 95% CI= 1.16-9.12), and in G risk allele carriers of rs1801282 (OR= 1.85; 95% CI= 1.07-3.19), after adjustment for age, gender, lipid-lowering medication usage, physical activity and smoking status. Regarding MetS risk in the TARF study group, the G-allele of rs1800206 PPARA gene exhibited a significant OR of 3.75, after adjustment for gender, age, smoking status, and physical activity. Conclusion: The G alleles of the studied SNPs in the PPARA and PPARG genes are related to increased dyslipidemia risk. Furthermore, The G allele of the PPARA gene is related to increased MetS risk.
