Abstract: Background: The Pro12Ala polymorphism in the peroxisome Proliferator-activated receptor-gamma2 PPARγ2) gene that account for
metabolic dysfunction in women with polycystic ovary syndrome (PCOS) remain elusive. Aim: To explore the association between PPARγ2 gene
pro12ala polymorphism and the metabolic characteristics in Chinese women with PCOS. Methods: PPARγ2 gene Pro12Ala polymorphism was
assayed by PCR/RFLP methods in 120 Chinese women with PCOS and 118 normal subjects. All subjects were examined by anthropometry,
lipid profile, sex hormone, oral glucose tolerance tests and insulin tolerance tests. Results: In PCOS patients, women with the non-Pro/Pro
genotypes of the PPARγ2 gene Pro12Ala polymorphism showed statistically significantly higher fasting triglycerides (TG) levels and WHR value
than those with the Pro/Pro genotype (P=.006 for both). There was no significant difference with PPARγ2 Pro12Ala polymorphism distributions
between Chinese Han women with PCOS and controls. Conclusion: PPARγ2 gene Pro12Ala polymorphism was not supposed to be
susceptible genes in PCOS. However, in PCOS patients, the PPAR-gamma Pro12Ala polymorphism may modulate the concentrations of
serum fasting TG levels and fat-deposition in abdomen, respectively. (IJCEP1307021).
