In PROWESS, 4.1% (n = 65) of patients were heterozygous FV Leiden (VL +/–) carriers. Results: After discontinuation of oral anticoagulant therapy for a first VTE, we prospectively observed 287 patients, 83 (29%) of whom were heterozygous for FV Leiden. Recurrent VTE was seen in 17 (20%) of 83 patients with and 44 (21.6%) of 204 without FV Leiden. 2013-12-01 · Among the former, the most common inherited thrombophilia is heterozygous factor V Leiden mutation, which accounts for 11-21% of cases in observational studies , . VTE risk is further increased with pregnancy and oral contraceptives , .

2021-04-06 · Odds ratios of recurrent venous thrombosis, adjusted for age and sex, in individuals who were heterozygous carriers of either factor V Leiden or prothrombin G20210A, who were homozygous carriers of factor V Leiden and/or prothrombin G20210A, or who were double heterozygous carriers of both mutations were 1.2 (95% CI, 0.9 to 1.7), 0.7 (95% CI, 0.4 to 1.2), 0.9 (95% CI, 0.4 to 2.1), and 0.9 (95% 2020-08-15 · Heterozygous factor V Leiden is found in about 5% of the white population and is most common in people of Northern European descent and in some Middle Eastern populations, whereas the homozygous form is found in fewer than 1%. Factor V Leiden is less common in the Hispanic populations and is rare in Asian, African, and Native American populations. heterozygous FV Leiden carriers have a distinct survival advantage in mouse models of infection with highly viru-lent human pathogens. Materials and methods Animals C57Bl/6J mice were obtained from Jackson Laboratories (Bar Harbor, ME, USA). Transgenic FV Leiden mice, fVIII /, Nfe2 /, EPCRLow, Par1 /, and Par4 / mice, have been described earlier [15–21]. Therefore, heterozygous FV Leiden patients should receive secondary thromboprophylaxis for a similar length of time as patients without FV Leiden.

Heterozygous means that the 2 copies of a gene are different. In your case, one of your Factor V gene codes is for normal clotting Factor V and the other Factor V gene code is for Factor V Leiden. There is more risk of a blood clot if both gene codes are for Factor V Leiden (ie in the homozygous state). The current study shows, for the first time, that heterozygous carriers of the fV Leiden allele benefit from a selective survival advantage over homozygous fV Leiden carriers and carriers of the normal fV allele in two distinct modes of infection with human bacterial pathogens, i.e. gram-positive S.aureus and gram-negative Y.pestis KIM5. Factor V Leiden is a variant of human factor V, which causes an increase in blood clotting. Due to this mutation, protein C, an anticoagulant protein which normally inhibits the pro-clotting activity of factor V, is not able to bind normally to factor V, leading to a hypercoagulable state, i.e., an increased tendency for the patient to form abnormal and potentially harmful blood clots.

People with factor V Leiden thrombophilia have a higher than average risk of developing a type of blood clot called a deep venous thrombosis (DVT). Factor V Leiden mutation (FVL) is an autosomal dominant hemostatic disorder that predisposes affected persons to venous thromboembolic events (VTE). Although the mutation causing FVL is easily diagnosed using molecular DNA techniques, 1 patients who are heterozygous for this disorder often remain asymptomatic until they develop a concurrent It is not correct to categorically state, that a woman who has factor V Leiden or the prothrombin 20210 mutation should not take a combined oral contraceptive pill.

The presence of FV Leiden, FII G20210A and MTHFR C677T mutations was detected by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis. In patients with DVT of lower limbs, the frequency of FV Leiden mutation was 26,0% in heterozygous form and 1,3% in homozygous form. Factor V Leiden mutation (FVL) is an autosomal dominant hemostatic disorder that predisposes affected persons to venous thromboembolic events (VTE). Although the mutation causing FVL is easily diagnosed using molecular DNA techniques, patients who are heterozygous for this disorder often heterozygous carriers of FV Leiden mutations are neither protected from infection and sepsis . per se, nor from disease progression into clinically defined severe sepsis.
Laboratory studies for thrombophilic disorders showed double-homozygosity for FV Leiden and the FII mutation, detected by polymerase chain reaction.
