Abstract
Introduction and hypothesis
Pelvic organ prolapse (POP) in women is a common condition whose etiology is poorly understood. There is increasing evidence that POP is heritable. The aim of our study was to define and evaluate familial clustering of POP.
Methods
Using a population-based Utah genealogy linked to more than a decade of hospital data, we calculated relative risks (RR) of POP in female relatives of women with POP using age- and birth year-specific rates of POP. We compared the average pairwise relatedness of all POP cases to the population using a measure of genetic distance.
Results
We identified 1,292 women with diagnostic and procedure codes for POP. The RR of POP was significantly elevated in first- and third-degree female relatives (RR 4.15, p < 0.001; RR 1.24, p = 0.05). The average pairwise relatedness for all individuals with POP was significantly higher than expected (p < 0.001).
Conclusions
These results strongly support a significant heritable contribution to POP.
