Abstract

BACKGROUND: The purpose of this study was to determine whether variability in gene encoding for promoter of tumor necrosis factor participates to women differences in susceptibility to endometriosis.

MATERIALS AND METHODS: The study involved 130 women; 65 endometriotic and 65 healthy control women. The blood samples were genotyped for -850 T/C and -863 C/A polymorphisms in TNF alpha gene promoter. Chi-square, odd ratio, and confidence interval 95% were used to evaluate genotypes and allele frequency differences between two groups.

RESULTS: No significant differences in genotypes distribution of -850 T/C (P = 0.32) and 863 C/A (P = 0.34) polymorphisms were obtained between two groups.

CONCLUSION: According to this study, these two polymorphisms have no risk or protective factor to develop endometriosis.
