The role of thrombofilia related to Factor V Leiden and Factor II G20210A mutations in recurrent abortions

J Pak Med Assoc. 2005 Mar;55(3):104-8.

Abstract

Objective: To study, the impact of thrombophilia caused by Factor V, Factor ll G20210A mutations on recurrent abortions, the prevelance of Factor V Leiden and Factor II G20210A mutation in patients with habitual abortions.

Methods: Forty one patients with a diagnosis of habitual abortion were enrolled in the study. Control group consisted of 50 women without a history of poor obstetric outcome. 10 ml. peripheral venous blood was taken from study and control groups and transferred to EDTA tubes, and were tested for Factor V Leiden and Factor II G20210A mutations by PCR in genetics laboratory.

Results: Phenotypes of 91 cases were determined by PCR for Factor V Leiden. It was established that of 41 patients in the study group, 31 (75.6%) had GG genotype, 9 (22%) had GA genotype and 1 (2.4%) had AA genotype. In the control group, 45 (90%) of 50 women had GG genotype and 5 (10%) had GA genotype. A allele carrier status was found to be 24.4% in study group and 10% in the control group. The difference between them was not statistically significant (p = 0.06).

Conclusions: The results obtained from patients and control group have no difference in Factor V Leiden and Factor II G20210A mutations.These results suggest that mutations have no role in etiology of 1. and 2. trimester recurrent abortions.
