Estrogen and estrogen receptors are known to play important roles in the pathophysiology of pelvic organ prolapse (POP). We investigated whether estrogen receptor β (ERβ) gene polymorphisms were associated with POP by conducting a case-control association study in 69 women with POP and 141 women without POP.
Study design
Genotypes of the ERβ gene polymorphisms (rs2987983, rs1271572, rs944459, rs1256049, and rs1255998) were determined by polymerase chain reaction, followed by restriction fragment length polymorphism analysis. Haplotyping analysis was used to determine the relationship among five polymorphisms in the ERβ gene and POP.
Results
There was no significant difference between women with and those without POP in the distribution of any of the genotypes evaluated. In haplotype frequency estimation analysis, haplotype CGCGC was more prevalent in women with POP (16.7%) than in women without POP (8.9%) (p = 0.011). Using multivariable logistic regression, age, parity and haplotype CGCGC were significantly associated with POP.
Conclusion
Although the sample size of women with POP studied is small, the present study shows that ERβ gene haplotype may be associated with POP.
