INTRODUCTION: We aimed to investigate the relationship between preeclampsia and inherited thrombophilias such as MTHFR gene mutations, factor V Leiden mutations and prothrombin gene mutation; and to assess the significance of the relationship at mild, severe and early-onset preeclampsia. METHODS: 68 preeclamptic pregnants diagnosed between October 2008 and March 2010 according to the American College of Obstetrics and Gynecology (ACOG) guideline 2002, and 70 healty pregnant women who carried her pregnancy beyond term (37 weeks and after) without any complications and applied to Bakirkoy Maternity and Children Hospital were taken into study and control groups. 5 ml venous blood were taken from each women in both groups and genetic evaluation is done at laboratory. RESULTS: AFactor V Leiden, MTHFR C677T, and prothrombin homozygous or heterozygous mutations were not statistically different between preeclamptics and healty pregnants. Comparisons for the mutations between severe preeclampsia and control cases were not statistically different. Cases with early-onset preeclampsia that occured before 34 weeks and 28 weeks, and the preeclamptic cases complicated by IUGR, were also assessed separately and mutations were not statistically different between study and control cases. The ratio of having at least one mutation in healty patiens were 64 percent, and the most common mutation was MTHFR heterozygous polymorphism. DISCUSSION AND CONCLUSION: Although pregnancy complications, maternal and fetal morbidity and mortaliy was higher in severe preeclampsia; presence of thrombophilic gene mutations was not statistically different from healty pregnants. Because the association between preeclampsia and thrombophilia is unproven yet, using such genetic markers as routine screening for thrombophilia or prognostic tools is not recommended.
