OBJECTIVE: This study aimed to verify the presence of polymorphism rs2165241 of the lysyl oxidase-like 1 (Loxl1) gene and its association with pelvic organ prolapse (POP) in Brazilian women and determine risk factors for POP development.
METHODS: The study was previously approved by the local research and ethics board. Postmenopausal women were included and divided into POP (stages III and IV) and control (stages 0 and I) groups. Peripheral blood samples were collected, and the DNA sequence of interest was analyzed by real-time reverse-transcriptase polymerase chain reaction. We used logistic regression and considered a recessive model of inheritance for the analysis, with p < 0.05 for significance.
RESULTS: A total of 836 women were assessed: 426 POP cases and 410 controls. The frequencies of CC, CT and TT genotypes were similar in both groups. Age (odds ratio [OR] = 1.1, 95% confidence interval [CI] = 1.07; 1.14), number of vaginal births (OR = 17.06, 95% CI = 5.94; 48.97), family history (OR = 2.87, 95% CI = 1.57; 5.22) and weight of largest newborn (OR = 1.001, 95% CI = 1.0003; 1.001) were independent risk factors for POP, while multiple cesarean sections (two or more) was protective (OR = 0.17, 95% CI = 0.07; 0.42).
CONCLUSION: No association was detected between rs2165241 of the Loxl1 gene and POP.
