Developing a polygenic risk score for pelvic organ prolapse: a combined risk assessment approach in Chinese women
Higher Education PressPelvic organ prolapse (POP), a condition whose development is shaped by both genetic and clinical risk factors, significantly impairs women’s quality of life, yet genetic insights into non-European populations and comprehensive risk models that integrate genetic and clinical data remain insufficiently explored. To address this gap, the first polygenic risk score (PRS) for POP in the Chinese population was constructed, leveraging 20 disease-associated genetic variants derived from the largest available genome-wide association study (GWAS) on POP. The research analyzed two cohorts: a discovery cohort comprising 576 POP cases and 623 controls, and a validation cohort with 264 cases and 200 controls. Results confirmed that the POP case group had a significantly higher PRS than the control group; notably, women in the top 10% of PRS values (highest genetic risk) had an odds ratio of 2.6 for developing POP compared to those in the bottom 10% (lowest genetic risk). A high PRS was also found to correlate significantly with POP occurrence in specific subgroups: women over 50 years old and those with one or no childbirths. Additionally, an integrated prediction model combining PRS with clinical risk factors demonstrated better predictive accuracy than existing PRS-only models. This combined risk assessment tool proves robust for POP risk prediction and stratification, providing valuable guidance for personalized preventive measures and treatment strategies in future clinical practice.
