BACKGROUND: Glutathione S-transferases (GSTs) protect cells from oxidative stress (OS). In humans, the GST omega class contains two expressed genes, GSTO1 and GSTO2. Because OS is involved in the pathogenesis of polycystic ovary syndrome (PCOS), the aim of this study was to investigate the relationship between GSTO1 A140D (rs4925) and GSTO2 N142D (rs156697) polymorphisms in PCOS patients.
METHODS: 175 PCOS patients and 161 healthy controls were selected among women in Kermanshah province, Iran. GSTO1 and GSTO2 were genotyped using allele-specific PCR (AS-PCR) and PCR-RFLP, respectively.
RESULTS: For GSTO1, the DD genotype and the D allele led to 2.17- (P= 0.02) and 1.5-fold (P= 0.01) increases, respectively, in the odds ratios for PCOS. No significant difference was found between control and patient groups for the GSTO2 N142D genotype or allele frequency. GSTO1 and GSTO2 genotype interaction analysis showed that individuals with the GSTO1 AD or DD genotypes and the GSTO2 NN or DN genotypes had a 1.53-fold (P= 0.007) increase in PCOS risk over GSTO1 AA and GSTO2 DD individuals.
CONCLUSION: The GSTO1 A140D polymorphism is a risk factor for PCOS.
