Abstract
Background and AimInfertility in women has various causes, one of which is ovulation disorders. Polycystic ovary syndrome (PCOS) affecting ovulation is a complex idiopathic disease in which genetic polymorphisms may be involved. This study aimed to investigate the relationship between IL-6 -174 G/C and IL-1A -889 G/A cytokine polymorphisms with polycystic ovary syndrome in a population of Iranian women. Materials and MethodsIn this case-control pilot study, 120 PCOS patients (60 infertile, LPI, and 60 women with recurrent pregnancy abortion, LPA) and 60 controls, CTRLs) participated. After genomic DNA extraction from peripheral blood, we investigated for the polymorphisms rs1800795 of the IL-6 -174 and rs1800587 of the IL-1A-889 using specific primers and PCR-RFLP followed by NlaIII enzyme digestion and PCR-ARMS techniques. ResultsThere was a significant difference in the studied groups in terms of clinical characteristics (p-value < 0.05) except for the levels of HDL and LDL. Regarding demographic and clinical characteristics of patients, a significant correlation was observed between C/G and G/G genotypes of rs1800795 and FBS level (p value = 0.002). Also, rs1800587 showed a substantial relationship between CC and CT genotypes with the level of LH in LPI and the level of FBS in the LPAs (p value = 0.04). There was no significant difference between the frequencies of rs1800795 and frequencies of rs1800587 genotypes in the three studied groups (p value > 0.05).The studied variants were in Hardy-Weinberg equilibrium. ConclusionThe present work showed that rs1800795 and rs1800587 were not directly associated with PCOS in Iranian patients while the SNPs showed an indirect relationship with some factors affecting the disease.However, using genome-wide association analysis is a proper suggestion to obtain more reliable information about the disease’s genetic view. To our knowledge, this is the first report that implicates the role of the examined SNPs in an Iranian PCOS population.
