Purpose of the research: The aim of our study is to investigate the association between the impact of Transforming Growth Factor Beta-1 (TGFβ1) 29T/C and E-Cadherin-160C/A polymorphisms and occurrence of ectopic pregnancy. Materials and methods: Our study was formulated as a case-control study where the genotype status of 95 women with a history of ectopic pregnancy were compared with 97 post-menopausal controls with at least two pregnancies and no history of ectopic pregnancy, with regards to

DNA was extracted from peripheral blood leukocytes using standard procedures. Genotype status of the samples in their TGFβ1 and E-Cadherin genes was determined by Polymerase Chain Reaction (PCR) using specific primers designed to specifically amplify wild-type sequence, and detected by endonuclease digestion coupled to electrophoretic determination of the sequences. The differences in genotype and allele frequencies between the cases and normal controls were compared using statistical analysis. The differences in TGFβ1 and E-Cadherin genotype and allele frequencies between the cases and normal controls were compared using the Chi-Square test. Statistical significance with a P value lower than 0.05 was considered significant. Statistical analysis was performed using the SPSS software. Principal results: Our analysis excluded the association of TGFβ1 29T/C and E-Cadherin 160C/A polymorphism with the occurrence of ectopic pregnancy. In this study, we did not observe and significant difference between the cases and controls in relation to the polymorphism of the TGFβ1 gene 29 T ⁄C (P = 0.289 ) and E-Cadherin gene -160 C ⁄A (P = 0. 572). Similar conclusions were valid for the frequencies of other alleles as well. Citation : Aghayeva N, Benian A, Yaylım İ, et al.
