Purpose: To evaluate the possible influence of G → T substitution at the Sp1-binding site of the COLIA1 gene on the risk of pelvic organ prolapse (POP). Materials and Methods: The study group consisted of 15 women with advanced stage POP. Fifteen control subjects with uterine myomas among the postmenopausal women were matched for age and parity. DNA was obtained from peripheral blood leukocytes. The fragments of the first intron of the COLIA1 gene were amplified by real time polymerase chain reaction. The polymorphism was identified using LightCycler Technology with hybridization probes. Sequencing reactions were performed on each template using commercial primer. Results: Two groups had no significant difference in medical history, surgical, and smoking history. The homozygous peaks in two groups were noted at 57° C on melting curve analysis. Sequencing reactions confirmed the G/G alleles in the 30 specimens tested. We could not find any polymorphism at the Sp1-binding site in COLIA1 gene with advanced stage POP. Statistical significance was considered to be p < .05. Conclusion: The polymorphism of the Sp1-binding site in the COLIA1 gene did not contribute to the development of POP in Korea.
