Objective: To investigate whether pelvic organ prolapse (POP) is associated with collagen 3 alpha 1 (COL3A1) polymorphisms and other factors.
Methods: A case-control association study was conducted with 84 women affected with POP and 147 controls. The genotypes of nucleotides COL3A1 rs1800255 and COL3A1 rs1801184 polymorphisms were ascertained by polymerase chain reaction and restriction fragment length polymorphism analysis.
Results: The distribution of the COL3A1 rs1800255 genotypes was significantly different among affected women and controls. Older age and incidence of COL3A1 rs1800255 genotype AA were significantly associated with risk of POP.
Conclusion: There may be an association between COL3A1 genotype and risk of POP.
