Polymorphisms of plasminogen activator inhibitor-1, angiotensin converting enzyme and coagulation factor XIII genes in patients with recurrent spontaneous abortion.

We investigated polymorphisms of plasminogen activator inhibitor-1 (PAI-1), angiotensin converting enzyme (ACE ) and coagulation factor XIII (FXIII) genes and their association with recurrent spontaneous abortion (RSA) in Iranian patients and normal healthy controls. Ten (18.5%) patients were homozygote (4G/4G) for PAI-1 polymorphism, in contrast with two (2%) controls (p = 0.

Thrombophilic mutations in Iranian patients with infertility and recurrent spontaneous abortion.

Factor V Leiden (FVL) G1691A, methylenetetrahydrofolate reductase (MTHFR) C677T, and factor II (FII) G20210A mutations are three important causes of thrombophilia, the condition that might be related to infertility and recurrent spontaneous abortion (RSA). In this study we evaluated the presence of these three mutations in 36 female patients with unexplained infertility, 65 female patients with unexplained RSA, and 62 healthy fertile women as control group. DNA was extracted from peripheral blood samples and PCR-RFLP was performed for the molecular diagnosis of each mutation.
