Abstract
Introduction and hypothesis
To investigate the associations between single nucleotide polymorphism (SNP) type 1G/2G at position −1607/−1608 of the matrix metalloproteinase (MMP)-1 gene and SNP type 5A/6A at position −1612/-1617 of the MMP-3 gene and the development of pelvic organ prolapse (POP) in women.
Methods
133 patients with symptomatic POP were included in the study group. The control group consisted of 132 women with a normal pelvic floor. 1G/2G MMP-1 and 5A/6A MMP-3 SNPs were determined by polymerase chain reaction (PCR) and restriction fragments length polymorphism analysis.
Results
When estimated individually none of the investigated SNPs were associated with POP. The combined MMP-1/MMP-3 SNP analysis showed that the following polymorphic pairs were overrepresented in women with POP: 1G/2G −5A/6A, 2G/2G −5A/6A, 2G/2G −5A/5A, 1G/1G −6A/6A, p = 0.005.
Conclusions
The combined effect of −1607/−1608 MMP-1 and −1612/−1617 MMP-3 SNPs may contribute to the development of POP in some women.
