Plasminogenactivator inhibitor-1 polymorphism and risk of polycystic ovary syndrome in Turkish women

Objective

Polycystic ovary syndrome(PCOS) is a chronic systemic disease with a multifactorial etiology resulting from complex interactions of environmental and genetic factors rather than a local disease. There are recently identified several abnormalities related to the hemostatic and fibrinolytic systems. Therefore, the study is performed to investigate the association between plasminogen activator inhibitor-1(PAI-1) -844G > A rs2227631 polymorphism and risk of PCOS.

Subject and methods

Two hundred fourteen voluntary premenopausal women (104 healthy controls and 110 PCOS patients) of similar age were included in the study. All volunteers underwent a physical examination and biochemical hormonal evaluation. PAI-1-844G > A rs2227631 variant was analysed using polymerase chain reaction and restriction fragment length polymorphism (PCR–RFLP) method. Women were diagnosed with PCOS according to the criteria of the Androgen Excess-PCOS Society.

Results

In PAI-1-844G > A, “A” additive model, AG vs. GG (OR: 2.6; 95%Cl: 1.09–6.17 p = 0.94) or AA vs. GG (OR: 2.3; 95%Cl: 0.87–5.96 p = 0.094) genotype increased the PCOS risk almost 2.5-fold. “G” dominant model, AG + GG vs. AA (OR: 0.97; 95%Cl: 0.52–1.81 p = 0.93) was not associated with PCOS risk. “G” recessive model, GG vs. AG + AA genotype reduced the risk of PCOS 2.6-fold (OR: 0.39; 95%Cl: 0.17–0.93 p = 0.033). “A” dominant model, AG + AA vs. GG genotype increased the risk of PCOS 2.5-fold (OR: 2.5; 95%Cl: 1.08–5.83 p = 0.033).

Conclusion

The rs2227631 is related to PCOS risk in Turkish Women. The study indicated that the “AA” genotype was correlated with an increased risk of PCOS while the “GG” genotype reduced the PCOS risk in Turkish women.
