Correlation between endometriosis combined with infertility and STAT3 gene polymorphisms

摘要

Objective:To investigate the correlation between STAT3 gene polymorphisms and endometriosis complicated with infertility.Methods: A total of 35 patients with endometriosis complicated with infertility and 35 cases of healthy volunteer from October 2014 to October 2015 in our hospital were selected as research objects. STAT3 gene polymorphisms of all objects were detected by PCR-RFLP method.Results: Polymorphic sites of STAT3 gene rs2293152 were expressed as three genotypes, namely, CC, GC, and GG. There were 18 cases, 10 cases and 7 cases of type CC, GC and GG in the observation group, accounted for 51.43%, 28.57% and 20.00%, respectively. There were 29 cases, 3 cases and 3 cases of type CC, GC and GG in the control group, accounted for 82.86%, 8.57% and 8.57%. There was a statistically difference` between the two groups. The frequency of C and G allele in the observation group and the control group were 65.71%, 34.29% and 87.14%, 12.86%, respectively. There were statistically significant differences between two groups. In addition, compared with the CC genotype, genotype G might increase the risk of the disease.Conclusions:The susceptibility of endometriosis complicated with infertility may be associated with STAT3 gene polymorphism and women who carried the G allele may have an increased the risk of the disease.
