Background: Polycystic ovary syndrome (PCOS) is known as the most common endocrine and metabolic disorder in the reproductive-age women. Due to the effects of PCOS on the physical and mental health, the investigation of the factors affecting the development of PCOS is crucial. Hexose-6-phosphate dehydrogenase (H6PD) is a microsomal enzyme that catalyzes the first two reactions of the oxidative chain of the pentose phosphate pathway. The present study examined the polymorphisms of the H6PD gene (R453Q and D151A) in PCOS patients of Iranian Kurdish women.
Materials and Methods: In this case-control study, a total, of 200 female volunteers in two equal groups participated in our study. The PCOS patients were selected based on the Rotterdam diagnostic criteria. The association of H6PD gene polymorphisms, D151A and R453Q, with the development of PCOS were investigated. The polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method was used for genotyping. Statistical analysis was applied by the SPSS (version 16) software.
Results: Statistically significant lower frequencies of AA+AG genotype (37% vs. 55%, P=0.01) and A allele (22.5%
vs. 34%, P=0.01) of R453Q were observed in the patients compared to the controls. In the case of D151A, no significant
differences were observed in the frequency of genotypes and alleles between the two groups.
Conclusion: The findings of this study suggest that variants of H6PD R453Q affect the risk of PCOS.
