Impact of Factor V Leiden, prothrombin and methylenetetrahydrofolate reductase gene mutations on infant birth weight in women with recurrent fetal loss and women with successful pregnancies

Clin Exp Obstet Gynecol. 2012;39(3):359-61.

Abstract

Purpose: The aim of this study was to verify whether FV Leiden, PT G20210A, MTHFR C667T or MTHFR A1298C mutations influence the risk of recurrent fetal loss in a sample of Turkish women who had experienced recurrent fetal loss and to evaluate whether the aforementioned thrombophilias and recurrent fetal loss may affect the birth weight of subsequent pregnancies.

Methods: Fifty-eight women with recurrent pregnancy loss and 30 women with successful pregnancies were evaluated.

Results: The average birth weights for infants of all women in the study group and for infants of thrombophilia-positive women in the study group were markedly lower than the birth weight of infants in the control group (p<0.001 and p<0.001, respectively).

Conclusion: Successful pregnancies in women with a history of recurrent fetal losses may be associated with lower birth weights compared to controls, irrespective of thrombophilia status. This conclusion warrants further research.
