This case-control study evaluated whether estrogen-related gene polymorphisms are associated with endometriosis in a large Brazilian sample, testing 500 women with endometriosis and 500 fertile controls for CYP2C19 (rs11592737) and HSD17B1 (rs605059) variants using TaqMan real-time PCR, with chi-square and logistic regression analyses and Hardy-Weinberg equilibrium checks. The CYP2C19 polymorphism showed statistically significant differences in genotype and allele frequency between cases and controls (p = 0.0203), with additional evidence by stage comparison (p = 0.0133 for stages I/II), whereas HSD17B1 differences were not statistically significant (p = 0.0687). The study reports CYP2C19 as potentially associated with endometriosis and considers it a potential biomarker, with the limitation that HSD17B1 showed no significant association and stage-specific findings for later stages were not significant (p = 0.0564). This paper is centrally about endometriosis — it demonstrates an association between a CYP2C19 polymorphism and endometriosis risk in Brazilian women.

Abstract

Purpose Estrogen metabolizing gene mutations can be associated with defective hormonal signaling leading to disease processes. Endometriosis is an estrogen dependent that can be influenced by defective signaling in the estrogen pathway.

Objectives

To evaluate the association of A/G 85952 CYP2C19 and A/G 937 HSD17B1 gene polymorphisms with endometriosis through the investigation of a large Brazilian sample of women with endometriosis and a fertile control group.

Methods

Five hundred women with endometriosis and 500 women without endometriosis were tested for CYP2C19 and HSD17B1 polymorphisms, by TaqMan Real Time PCR. The results were statistically analyzed by chi-square, logistic regression and tested for Hardy-Weinberg equilibrium.

Results

The comparison of genotype and allelic frequency of CYP2C19 polymorphism (rs11592737) in patients with endometriosis and control group showed a statistically significant difference (p = 0.0203) and for the HSD17B1 polymorphism (rs605059) differences were not significant (p = 0.0687). Comparing the stages I/II and III/IV endometriosis with the control group for the CYP2C19 we observed p = 0.0133 and p = 0.0564, respectively, and for HSD17B1 the values for p = 0.4319 and p = 0.0667.

Conclusion

We observed that CYP2C19 polymorphism is associated with endometrisis in Brazilian women and can be considered a potential biomarker of the disease. Similar content being viewed by others

Author information Authors and Affiliations Corresponding author Additional information Capsule In a case-control study comprising 500 women with endometriosis and 500 women without the disease we were able to demonstrate a statistically difference considering genotype and allelic frequency of CYP2C19 polymorphism (rs11592737). Comparing endometriosis cases classified as stages I/II and III/IV with control group for the CYP2C19 we observed that the polymorphism is more frequent in the cases with stages I/II. Regarding HSD17B1 polymorphism no association was also found. We concluded that CYP2C19 polymorphism is associated to endometriosis in Brazilian women and can be considered a potential biomarker of the disease.
