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).

A postmortem genetic testing for common mutations resulting in thrombophilia should be performed in all individuals who die as a result of thrombosis, regardless of predisposing risk factors, to determine the true prevalence of mutations in these individuals, and to assess the true role of a certain mutation, such as heterozygote MTHFR C677T, in the pathogenesis of thrombosis.

Prevalence of thrombophilia was, respectively: protein S deficiency (11.5% versus 5.5%), protein C deficiency (0.76% versus 1%), resistance to activated protein C (2.3% versus 3.5%), mutation in V Leiden factor (1.5% versus 2%), antithrombin III deficiency (0% versus 0%), lupus anticoagulant (0% versus 0.5%), anticardiolipin antibodies (3% versus 10%; P=0.01), hyperhomocysteinemia (31.5% versus 53.5%; P=0.0001), mutation of the MTHFR gene in homocigosis (10% versus 5%), and heterocigosis (27.6% versus 41.9%; P=0.01).

While it is important to consider that milder forms of pyridoxine-responsive classical homocystinuria will be detected only by tHcy, we suggest that routine testing of MTHFR c.677C>T genotype as part of a thrombophilia evaluation in children with incident thromboembolism is not warranted until larger studies have been performed in order to establish or refute a link between MTHFR and adverse outcomes.

Based on the hypothesis that an inherited predilection to hypercoagulability may predispose to HSP or may mark those who develop acute clinical manifestations, we evaluated the possible roles of methylenetetrahydrofolate reductase (MTHFR) gene C677T, factor V (FV) gene G1691A (Leiden), and prothrombin gene G20210A polymorphisms in patients with HSP.

The purpose of this study was to determine (1). whether the inherited thrombophilias (the factor V Leiden and prothrombin gene mutations and the methylenetetrahydrofolate reductase [C677T] polymorphism) are increased in women with "idiopathic" (normotensive) small-for-gestational-age pregnancies and/or in their babies and (2). whether fetal carriage of a thrombophilia is associated with abnormal umbilical Doppler studies.

The thermolabile variant (TT) of the methylenetetrahydrofolate reductase (MTHFR) gene, and homozygosity for the 4G allele of the promoter region of the plasminogen activator inhibitor-1 (PAI-1) are potential genetic polymorphisms that have not been consistently associated with increased risk of VT. A case-control study was performed on 192 consecutive unrelated patients referred for evaluation of thrombophilia because of VT and 200 healthy controls.
