Abstract
Objective
To investigate the relationship between IL-6 −174G/C promoter polymorphism and preeclampsia.
Methods
A total of 140 preeclamptic women and 135 women with normal pregnancy were considered for the present study. A standard amplification refractory mutation system PCR was carried out for genotyping of IL-6 G−174C promoter polymorphism. Genotypic distribution was compared with values predicted by Hardy–Weinberg equilibrium using χ 2 test. Odds ratios and their respective 95 % confidence intervals were used to measure the strength of association.
Results
The frequencies observed, CC, GC and GG, were 53.5, 26.6 and 20 % in patients and 26.6, 23.7 and 49.6 % in the controls. There is a significant difference in the distribution of genotypes and alleles of IL-6 G−174 C between the two groups.
Conclusion
The present study suggests that the IL-6 −174 promoter polymorphism is a major genetic regulator in the etiology of early-onset preeclampsia.
