The role of TNF-α and il-6 SNP in polycystic ovary syndrome susceptibility.

Abstract

Aim: To shed the light on the impact of TNF-α 1031 T/C (rs-1800629) and IL-6 174 G/C (rs1800795) polymorphism with disease susceptibility and development. Materials and Methods: A case-control study has been established based on 50 women with confirmed diagnosed polycystic ovarian syndrome, and 50 healthy controls. Allele specific PCR have been done in order to study SNP of TNF-alpha and IL-6 in both groups. Result: The findings of the present investigation indicated that there was a signif i cant dif f erence in the frequency distribution of TNF-alpha 1031 T/C SNP according to genotype between patients and controls group p = 0.02. In addition, there is a high significant difference in the frequencies of distribution of alleles (T/C) between patients and control group p = 0.001. There was a signif i cant dif f erence in the frequency distribution of IL-6 174 G/C between patients and controls group p = 0.026. In addition, there is a signif i cant dif f erence in the frequencies of distribution of participants according to allele (G/C) between patients and control group p = 0.047. Genotype GC was significantly lower in patients' group and genotype GG was high significant in patients' group in comparison with a control group and the differences were significant, p = 0.024 and 0.006, respectively. Conclusions: The present study concluded that IL-6 174 G/C, (rs:1800795) single nucleotide polymorphism (SNP) and TNF-alpha 1031 T/C (rs-1800629) were associated with PCOS susceptibility, and GG genotype in IL-6 and C allele in TNF are considered as risk factor.
