Relationship between Coagulation Factors and Polymorphism of Effective Thrombophilic Genes with Recurrent Abortions

Gene mutations leading to thrombophilic disorders and changes in blood coagulation factors during pregnancy play an important role in the occurrence of recurrent abortions. This study was conducted to determine the relationship between polymorphism of thrombophilic genes and coagulation factors in women with recurrent miscarriage.

In this descriptive-analytical study, 29 women with a history of recurrent abortions (at least three times) were investigated. Demographic data were collected. Total genomic DNA was isolated from peripheral blood. The presence or absence of mutation in factor II (G20210A), factor V Leiden (G1691A), factor V HR2 (H1299R), MTHFR C677T, and MTHFR A1298C polymorphisms were assessed by PCR.

Coagulation factors and thrombophilic mutations had no significant association with recurrent miscarriage.

The results obtained in this study showed that none of the studied polymorphisms could justify frequent abortions in women. Therefore, it is suggested to evaluate genetic factors in normal individuals or immediate and extended family of the study population with no miscarriage history.
