Heat- and storage-labile plasma glycoprotein which accelerates the conversion of prothrombin to thrombin in blood coagulation. Factor V accomplishes this by forming a complex with factor Xa, phospholipid, and calcium (prothrombinase complex). Deficiency of factor V leads to Owren's disease.
A deficiency of blood coagulation factor V (known as proaccelerin or accelerator globulin or labile factor) leading to a rare hemorrhagic tendency known as Owren's disease or parahemophilia. It varies greatly in severity. Factor V deficiency is an autosomal recessive trait. (Dorland, 27th ed)
A hemostatic disorder characterized by a poor anticoagulant response to activated protein C (APC). The activated form of Factor V (Factor Va) is more slowly degraded by activated protein C. Factor V Leiden mutation (R506Q) is the most common cause of APC resistance.
A plasma protein that is the inactive precursor of thrombin. It is converted to thrombin by a prothrombin activator complex consisting of factor Xa, factor V, phospholipid, and calcium ions. Deficiency of prothrombin leads to hypoprothrombinemia.

An autosomal dominant disorder showing decreased levels of plasma protein S antigen or activity, associated with venous thrombosis and pulmonary embolism. PROTEIN S is a vitamin K-dependent plasma protein that inhibits blood clotting by serving as a cofactor for activated PROTEIN C (also a vitamin K-dependent protein), and the clinical manifestations of its deficiency are virtually identical to those of protein C deficiency. Treatment with heparin for acute thrombotic processes is usually followed by maintenance administration of coumarin drugs for the prevention of recurrent thrombosis.

Evidence suggesting the regulation of a coagulation factor levels in rabbits by a transferable plasma agent. (1/888)

New Zealand white rabbits were given 30 ml of goat serum intravenously. This procedure resulted in an immediate decrease in platelet count, fibrinogen, and levels of coagulation factors II, V, VII, and X, due to consumption coagulopathy. These factors returned toward baseline levels approximately 12 hr after the injection. Plasma from rabbits who had received goat serum 48 hr previously (donor rabbits) was injected into recipient rabbits. This procedure resulted in a slight rise in the level of coagulation factor II (range, 20%-30%) and a significant rise in factors V (35%-75%), VII (35%-235%), and X (35%-75%) in the recipients. When plasma from control donor rabbits who had not received goat serum was injected into recipients, there was no change in these coagulation factors. It is postulated that the reduction in coagulation factor levels in donor rabbits induces a "coagulopoietin" for each factor or one "coagulopoietin" for all factors which stimulates increased synthesis and/or release of these factors in recipient rabbits.  (+info)

Prospective evaluation of the thrombotic risk in children with acute lymphoblastic leukemia carrying the MTHFR TT 677 genotype, the prothrombin G20210A variant, and further prothrombotic risk factors. (2/888)

The reported incidence of thromboembolism in children with acute lymphoblastic leukemia (ALL) treated with L-asparaginase, vincristine, and prednisone varies from 2.4% to 11.5%. The present study was designed to prospectively evaluate the role of the TT677 methylenetetrahydrofolate reductase (MTHFR) genotype, the prothrombin G20210A mutation, the factor V G1691A mutation, deficiencies of protein C, protein S, antithrombin, and increased lipoprotein (a) concentrations in leukemic children treated according to the ALL-Berlin-Frankfurt-Muenster (BFM) 90/95 study protocols with respect to the onset of vascular events. Three hundred and one consecutive leukemic children were enrolled in this study. Fifty-five of these 301 subjects investigated had one established single prothrombotic risk factor: 20 children showed the TT677 MTHFR genotype; 5 showed the heterozygous prothrombin G20210A variant; 11 were carriers of the factor V G1691A mutation (heterozygous, n = 10; homozygous, n = 1); 4 showed familial protein C, 4 protein S, and 2 antithrombin type I deficiency; 9 patients were suffering from familially increased lipoprotein (a) [Lp(a)] concentrations (>30 mg/dL). In addition, combined prothrombotic defects were found in a further 10 patients: the FV mutation was combined with the prothrombin G20210A variant (n = 1), increased Lp(a) (n = 3), protein C deficiency (n = 1), and homozygosity for the C677T MTHFR gene mutation (n = 1). Lp(a) was combined with protein C deficiency (n = 2) and the MTHFR TT 677 genotype (n = 2). Two hundred eighty-nine of the 301 patients were available for thrombosis-free survival analysis. In 32 (11%) of these 289 patients venous thromboembolism occurred. The overall thrombosis-free survival in patients with at least one prothrombotic defect was significantly reduced compared with patients without a prothrombotic defect within the hemostatic system (P <.0001). In addition, a clear-cut positive correlation (P <.0001) was found between thrombosis and the use of central lines. However, because the prothrombotic defects diagnosed in the total childhood population studied were all found within the prevalences reported for healthy Caucasian individuals, the interaction between prothrombotic risk factors, ALL treatment, and further environmental factors is likely to cause thrombotic manifestations.  (+info)

G20210A mutation in prothrombin gene and risk of myocardial infarction, stroke, and venous thrombosis in a large cohort of US men. (3/888)

BACKGROUND: A single base pair mutation in the prothrombin gene has recently been identified that is associated with increased prothrombin levels. Whether this mutation increases the risks of arterial and venous thrombosis among healthy individuals is controversial. METHODS AND RESULTS: In a prospective cohort of 14 916 men, we determined the prevalence of the G20210A prothrombin gene variant in 833 men who subsequently developed myocardial infarction, stroke, or venous thrombosis (cases) and in 1774 age- and smoking status-matched men who remained free of thrombosis during a 10-year follow-up (control subjects). Gene sequencing was used to confirm mutation status in a subgroup of participants. Overall, carrier rates for the G20210A mutation were similar among case and control subjects; the relative risk of developing any thrombotic event in association with the 20210A allele was 1.05 (95% CI, 0.7 to 1.6; P=0.8). We observed no evidence of association between mutation and myocardial infarction (RR=0.8, P=0.4) or stroke (RR=1.1, P=0.8). For venous thrombosis, a modest nonsignificant increase in risk was observed (RR=1.7, P=0.08) that was smaller in magnitude than that associated with factor V Leiden (RR=3.0, P<0. 001). Nine individuals carried both the prothrombin mutation and factor V Leiden (5 controls and 4 cases). One individual, a control subject, was homozygous for the prothrombin mutation. CONCLUSIONS: In a large cohort of US men, the G20210A prothrombin gene variant was not associated with increased risk of myocardial infarction or stroke. For venous thrombosis, risk estimates associated with the G20210A mutation were smaller in magnitude than risk estimates associated with factor V Leiden.  (+info)

Single and combined prothrombotic factors in patients with idiopathic venous thromboembolism: prevalence and risk assessment. (4/888)

The inherited thrombophilias--deficiencies of protein C, protein S, and antithrombin III--and the prothrombotic polymorphisms factor V G1691A and factor II G20210A predispose patients toward venous thromboembolism (VTE). The aim of this study was to determine the prevalence of single and combined prothrombotic factors in patients with idiopathic VTE and to estimate the associated risks. The study group consisted of 162 patients referred for work-up of thrombophilia after documented VTE. The controls were 336 consecutively admitted patients. In all subjects factor V G1691A, factor II G20210A, and methylenetetrahydrofolate reductase (MTHFR) C677T were analyzed by specific polymerase chain reactions and restriction enzymes. Activities of antithrombin III and protein C, free protein S antigen, and lupus anticoagulant were determined in a subset of 109 patients who were not receiving oral anticoagulants. The prevalences of heterozygotes and homozygotes for factor V G1691A and factor II G20210A among patients and controls were 40.1% versus 3.9% and 18.5% versus 5.4%, respectively (P=0.0001). The prevalence of homozygotes for MTHFR C677T in patients was 22.8% and in controls, 14.3% (P=0.025). Heterozygous and homozygous factor V G1691A, factor II G20210A, and homozygous MTHFR C677T were found to be independent risk factors for VTE, with odds ratios of 16.3, 3.6, and 2.1, respectively. Two or more polymorphisms were detected in 27 of 162 patients (16.7%) and in 3 of 336 controls (0.9%). Logistic regression analysis disclosed odds ratios of 58.6 (confidence interval [CI], 22.1 to 155.2) for joint occurrence of factor V and factor II polymorphisms, of 35.0 (CI, 14.5 to 84.7) for factor V and MTHFR polymorphisms, and of 7.7 (CI, 3.0 to 19.6) for factor II and MTHFR polymorphisms. Among 109 patients in whom a complete thrombophilic work-up was performed, 74% had at least 1 underlying defect. These data indicate that in most patients referred for evaluation of thrombophilia due to idiopathic VTE, 1 or more underlying genetic predispositions were discernible. The presence of >1 of the prothrombotic polymorphisms was associated with a substantial risk of VTE.  (+info)

Interaction between the G20210A mutation of the prothrombin gene and oral contraceptive use in deep vein thrombosis. (5/888)

Single-point mutations in the gene coding for prothrombin (factor II:A20210) or factor V (factor V:A1691) are associated with an increased risk of venous thromboembolism. The use of oral contraceptives is also a strong and independent risk factor for the disease, and the interaction between factor V:A1691 and oral contraceptives greatly increases the risk. No information is available about the interaction between oral contraceptives and mutant prothrombin. We investigated 148 women with a first, objectively confirmed episode of deep vein thrombosis and 277 healthy women as controls. Fourteen patients (9.4%) were carriers of factor II:A20210, 24 (16.2%) of factor V:A1691, and 4 (2.7%) of both defects. Among controls, the prevalence was 2.5% for either factor II:A20210 or factor V:A1691, and there was no carrier of both the mutations. The relative risk of thrombosis was 6-fold for factor II:A20210 and 9-fold for factor V:A1691. The most prevalent circumstantial risk factor in patients and the only one observed in controls was oral contraceptive use, which per se conferred a 6-fold increased risk of thrombosis. The risk increased to 16.3 and 20.0 when women with factor II:A20210 or factor V:A1691 who used oral contraceptives were compared with noncarriers and nonusers. These figures indicate a multiplicative interaction between the genetic risk factors and oral contraceptives. No difference in the type of oral contraceptives was observed between patients and controls, those of third generation being the most frequently used (73% and 80%). We conclude that carriers of the prothrombin mutation who use oral contraceptives have a markedly increased risk of deep vein thrombosis, much higher than the risk conferred by either factor alone.  (+info)

Synergistic effects of prothrombotic polymorphisms and atherogenic factors on the risk of myocardial infarction in young males. (6/888)

Several recent studies evaluated a possible effect of the prothrombotic polymorphisms such as 5,10 methylenetetrahydrofolate reductase (MTHFR) nt 677C --> T, factor V (F V) nt 1691G --> A (F V Leiden), and factor II (F II) nt 20210 G --> A on the risk of myocardial infarction. In the present study, we analyzed the effect of these prothrombotic polymorphisms, as well as apolipoprotein (Apo) E4, smoking, hypertension, diabetes mellitus, and hypercholesterolemia, on the risk of myocardial infarction in young males. We conducted a case-control study of 112 young males with first acute myocardial infarction (AMI) before the age of 52 and 187 healthy controls of similar age. The prevalences of heterozygotes for F V G1691A and F II G20210A were not significantly different between cases and controls (6.3% v 6.4% and 5.9% v 3.4% among cases and controls, respectively). In contrast, the prevalence of MTHFR 677T homozygosity and the allele frequency of Apo E4 were significantly higher among patients (24.1% v 10.7% and 9.4% v 5.3% among cases and controls, respectively). Concomitant presence of hypertension, hypercholesterolemia, or diabetes and one or more of the four examined polymorphisms increased the risk by almost ninefold (odds ratio [OR] = 8.66; 95% confidence interval [CI], 3.49 to 21.5) and concomitant smoking by almost 18-fold (OR = 17.6; 95% CI, 6.30 to 48.9). When all atherogenic risk factors were analyzed simultaneously by a logistic model, the combination of prothrombotic and Apo E4 polymorphisms with current smoking increased the risk 25-fold (OR = 24.7; 95% CI, 7.17 to 84.9). The presented data suggest a synergistic effect between atherogenic and thrombogenic risk factors in the pathogenesis of AMI, as was recently found in a similar cohort of women.  (+info)

Thrombophilia as a multigenic disease. (7/888)

BACKGROUND AND OBJECTIVE: Venous thrombosis is a common disease annually affecting 1 in 1000 individuals. The multifactorial nature of the disease is illustrated by the frequent identification of one or more predisposing genetic and/or environmental risk factors in thrombosis patients. Most of the genetic defects known today affect the function of the natural anticoagulant pathways and in particular the protein C system. This presentation focuses on the importance of the genetic factors in the pathogenesis of inherited thrombophilia with particular emphasis on those defects which affect the protein C system. INFORMATION SOURCES: Published results in articles covered by the Medline database have been integrated with our original studies in the field of thrombophilia. STATE OF THE ART AND PERSPECTIVES: The risk of venous thrombosis is increased when the hemostatic balance between pro- and anti-coagulant forces is shifted in favor of coagulation. When this is caused by an inherited defect, the resulting hypercoagulable state is a lifelong risk factor for thrombosis. Resistance to activated protein C (APC resistance) is the most common inherited hypercoagulable state found to be associated with venous thrombosis. It is caused by a single point mutation in the factor V (FV) gene, which predicts the substitution of Arg506 with a Gln. Arg506 is one of three APC-cleavage sites and the mutation results in the loss of this APC-cleavage site. The mutation is only found in Caucasians but the prevalence of the mutant FV allele (FV:Q506) varies between countries. It is found to be highly prevalent (up to 15%) in Scandinavian populations, in areas with high incidence of thrombosis. FV:Q506 is associated with a 5-10-fold increased risk of thrombosis and is found in 20-60% of Caucasian patients with thrombosis. The second most common inherited risk factor for thrombosis is a point mutation (G20210A) in the 3' untranslated region of the prothrombin gene. This mutation is present in approximately 2% of healthy individuals and in 6-7% of thrombosis patients, suggesting it to be a mild risk factor of thrombosis. Other less common genetic risk factors for thrombosis are the deficiencies of natural anticoagulant proteins such as antithrombin, protein C or protein S. Such defects are present in less than 1% of healthy individuals and together they account for 5-10% of genetic defects found in patients with venous thrombosis. Owing to the high prevalence of inherited APC resistance (FV:Q506) and of the G20210A mutation in the prothrombin gene, combinations of genetic defects are relatively common in the general population. As each genetic defect is an independent risk factor for thrombosis, individuals with multiple defects have a highly increased risk of thrombosis. As a consequence, multiple defects are often found in patients with thrombosis.  (+info)

Factor V Leiden and antibodies against phospholipids and protein S in a young woman with recurrent thromboses and abortion. (8/888)

We describe the case of a 39-year-old woman who suffered two iliofemoral venous thromboses, a cerebral ischemic infarct and recurrent fetal loss. Initial studies showed high levels of antiphospholipid antibodies (APAs) and a moderate thrombocytopenia. After her second miscarriage, laboratory diagnosis revealed that the woman was heterozygous for the factor V Leiden mutation and had a functional protein S deficiency as well as anti-protein S and anti-beta 2-glycoprotein I antibodies. The impairment of the protein C pathway at various points could well explain the recurrent thromboses in the patient and supports the role of a disturbed protein C system in the pathophysiology of thrombosis in patients with APAs.  (+info)

Rare individuals have mutations of their factor V gene that alter cleavage of factor V by activated protein C but are different than the factor V Leiden mutation (e.g. factor V Hong Kong and factor V Cambridge). Most factor V Leiden genetic assays will not detect these mutations, but they are rare and their association with thrombotic risk is less well established than factor V Leiden.. The majority of plasma factor V is made in the liver. Most genetic tests for factor V Leiden evaluate DNA purified from white blood cells. Patients with bone marrow or liver transplants may show discrepancies between the factor V gene evaluated in white cell DNA and the factor V in plasma being produced by the liver. In bone marrow or liver transplant patients, the activated protein C resistance assay can be used to assess the factor V produced by the liver.. Some activated protein C resistance assays may suffer interference from lupus inhibitors, factor V deficiency, heparin or low molecular weight heparin, and ...

A 27-year-old man was admitted to our hospital with the complaints of swelling of his face and lower limbs. Echocardiography showed minimal pericardial effusion accompanied by disordered diastolic function. Cardiac catheterization was performed to rule out constrictive pericarditis. Normal pressure tracings of the right heart rule out constrictive pericarditis, however, a. narrowing of the inferior vena cava was observed. Venographies of the inferior and superior vena cavae showed extensive thrombotic involvement of these great veins. Protein C, protein S, anticardiolipin antibodies, fibrinogen, antithrombin-III, activated protein C resistance, and factor V levels were in normal limits. Heterozygosity for factor V Leiden mutation was detected. We conclude that factor V Leiden mutation can cause extensive thrombotic involvement of major veins and should be considered in idiopathic thrombosis of them. ...
Factor V Leiden is a common inherited genetic disorder in which your blood has an increased tendency to form clots (thrombophilia), usually in your veins.. Although blood clots can form at any age, for most people the increased risk of clotting doesnt begin until adulthood. Most people with factor V Leiden never develop abnormal clots. However, some people with factor V Leiden develop clots that lead to long-term health problems or are life-threatening.. Both men and women can have factor V Leiden, but women may have an increased tendency to develop blood clots during pregnancy or when taking the hormone estrogen.. If you have factor V Leiden, medications can lessen your risk of developing blood clots and help you avoid potentially serious complications.. Its possible to have factor V Leiden without ever developing signs or symptoms. However, the first indication that you have the disorder may be the development of a blood clot (thrombosis).. Some clots do no damage and disappear on their own. ...

Background. If a thrombophilia (clotting disorder) has been identified in a patient with blood clots (venous thromboembolism = VTE), the question arises whether other family members should be tested for the same thrombophilia.. My Clinical Approach. My approach in clinical practice to thrombophilia testing in family members is summarized in table 1: Family Member Testing. If the patient has a strong inherited thrombophilia (i.e. homozygous factor V Leiden, homozygous prothrombin 20210 mutation, double heterozygous factor V Leiden plus prothrombin 20210 mutation, deficiency of protein C, S or antithrombin) then I consider and discuss testing of other family members. However, if the patient only has heterozygous factor V Leiden or heterozygous prothrombin 20210 mutation, I do not recommend testing of family members, as the finding of one of these mild thrombophilias typically has no impact on management of family members also affected by one of those mild thrombophilias.. Finding of a ...
Factor V Leiden (rs6025) is a variant (mutated form) of human factor V (one of several substances that helps blood clot), which causes an increase in blood clotting (hypercoagulability). With this mutation, the anticoagulant protein secreted (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. Factor V Leiden is the most common hereditary hypercoagulability (prone to clotting) disorder amongst ethnic Europeans. It is named after the Dutch city Leiden, where it was first identified in 1994 by Prof R. Bertina et al. Abnormal, recurrent venous thromboses. In the normal person, factor V functions as a cofactor to allow factor Xa to activate prothrombin, resulting in the enzyme thrombin. Thrombin in turn cleaves fibrinogen to form fibrin, which polymerizes to form the dense meshwork that makes up the majority of a ...
Six cases of congenital thrombophilia (15%) were found: 1 PC deficiency (patient 25), 1 PS deficiency (patient 34), and 4 heterozygous factor V Leiden (patients 21, 22, 28, and 30). Three patients had increased aCL antibodies, 1 with systemic lupus (patient 21) and 2 with a primary aPL syndrome (patients 8 and 22); 2 of these had also factor V Leiden mutation. There was no antithrombin or plasminogen deficiency. Cases with thrombophilia and/or aCL antibodies are briefly summarized. Treatment and outcome are not detailed because all patients received heparin followed by oral anticoagulants and made an uneventful recovery.. Patient 25 was 34 years old in 1986 when she complained of headache, seizures, and left-sided sensory symptoms in a context of uveomeningitis. No other signs of Behçets disease11 or sarcoidosis were present. Angiography and MRI showed right LS thrombosis. The patient has been well since then. While receiving oral anticoagulants, PC activity was 24%, antigen was 33%, and ...
What is factor V Leiden? The most common genetic risk factor for venous thrombosis is factor V Leiden, present in 5 percent of the general population. Factor V is one of the normal blood clotting factors. Factor V Leiden is a changed or mutated form of factor V that is inactivated 10 times slower than the normal factor V. This causes it to persist longer in the circulation, resulting in a hypercoagulable state. In other words, the blood continues clotting, resulting in possible obstruction.. One copy of the factor V Leiden gene increases the risk for venous thrombosis 4 to 8 times, while two copies of the gene increase the risk 80-fold.. Other coexisting coagulation defects can occur with factor V Leiden, and in general, the risk for thrombosis increases in patients with more than one genetic defect.. The factor V Leiden mutation is involved in 20 to 40 percent of venous thrombosis cases and is suspected in individuals who have a medical history of venous thrombosis or in families with a high ...
The relation between factor V mutation and risk for venous thromboembolism was confirmed in a prospective study of 14 916 men with no history of cardiovascular disease or cancer followed for a mean of 8.6 years. 11.6% of men with venous thromboembolism had the mutation compared with 6.0% of those with no thromboembolism (relative risk [RR] 2.7, 95% CI 1.3 to 5.6, P = 0.008). Risks were higher for patients with idiopathic events (RR 3.5, CI 1.5 to 8.4, P = 0.004) and for men , 60 years of age (adjusted RR 4.0, CI 1.6 to 9.7, P = 0.003). A prospective study showed that men with both factor V mutation and moderate hyperhomocystinemia had an increased risk for any form of venous thromboembolism (RR 9.7, P = 0.009) and for idiopathic venous thromboembolism (RR 21.8, P , 0.001) compared with men who had neither abnormality. In a case-control study comparing 155 premenopausal women who had deep venous thrombosis unrelated to a malignant condition with 169 women who had no history of thrombosis, the ...
Background: Activated Protein C Resistance (APCR), a poor anticoagulant response of APC in haemostasis, is the commonest heritable thrombophilia. Adverse outcomes during pregnancy have been linked to APCR. This study determined the frequency of APCR, factor V gene known and novel SNPs and adverse outcomes in a group of pregnant women. Methods:Blood samples collected from 907 pregnant women were tested using the Coatest® Classic and Modified functional haematological tests to establish the frequency of APCR. PCR-Restriction Enzyme Analysis (PCR-REA), PCR-DNA probe hybridisation analysis and DNA sequencing were used for molecular screening of known mutations in the factor V gene in subjects determined to have APCR based on the Coatest® Classic and/or Modified functional haematological tests. Glycosylase Mediated Polymorphism Detection (GMPD), a SNP screening technique and DNA sequencing, were used to identify SNPs in the factor V gene of 5 APCR subjects. Results:Sixteen percent of the study ...

A young woman 38 years of age underwent Doppler ultrasonography following the spontaneous appearance of cervical pain causing loss of sleep. The examination revealed bilateral dissection of the internal carotid arteries, confirmed by supraaortic arteriography. Two successive CT scans showed no cerebral lesions. A thrombosis of the great saphenous vein was recorded as the only vascular event in her medical history. Thrombophilia was assessed following discovery of the dissection, and upon examination a heterozygotic mutation of Factor V Leiden was revealed. This observation is the second case of carotid dissection occurring in a subject presenting a factor V mutation. At the present time, however, there are no results to justify the assumption of a direct link between these two pathologies.

Activated protein C (aPC), in a complex with protein S, inactivates procoagulant factors Va and VIIIa by proteolytic cleavage at specific arginine residues.7,10,11 This serves to control coagulation and limit the extent of thrombus formation. The functionality of the aPC inhibitory system in a given individual can be assessed through an in vitro clotting assay. Addition of aPC to a patients plasma serves to extend the activated partial thromboplastin time (aPTT) for individuals who are sensitive to aPC. Individuals are considered to be aPC resistant when addition of aPC fails to extend the time to clot formation in this assay. More than 95% of cases of aPC resistance are caused by a specific polymorphism in the factor V gene that is referred to as factor V Leiden.8 This single point mutation results in a substitution of glutamine for arginine at amino acid number 506 of factor V. Arginine number 506 is an aPC cleavage site of normal factor V, making factor V Leiden resistant to inactivation by ...

Individuals who carry the Factor V Leiden mutation have a 3- to 8-fold increased risk as heterozygotes and a greater than 10-fold increased risk as homozygotes. Individuals who carry the F2 prothrombin mutation have a 2- to 5-fold increased risk as heterozygotes and up to a 10-fold increased risk as homozygotes. Individuals who carry two copies of the 677C,T mutation, or one 677C,T and one 1298A,C mutation, in the MTHFR gene have between a 2- and 8-fold increased risk. Compound heterozygotes (heterozygous for more than one of the mutations tested for) have an even higher risk of thrombophilia. For example, a person that is heterozygous for both the Factor V Leiden mutation and heterozygous for the F2 prothrombin mutation has a greater than 20-fold increased risk ...
Factor V Leiden is an autosomal dominant condition which exhibits incomplete dominance and results in a Factor V variant which cannot be as easily degraded by aPC. The gene that codes the protein is referred to as F5. Mutation of this gene-a single nucleotide polymorphism (SNP) is located in exon 10.[6] As a missense substitution it changes a proteins amino acid from arginine to glutamine. Depending on the chosen start the position of the nucleotide variant is either at position 1691 or 1746.[7] It also affects the amino acid position for the variant which is either 506 or 534. Together with the general lack of nomenclature standard it means that the SNP can be referred to in several ways such as G1691A, c.1601G,A, 1691G,A, c.1746G,A, p.Arg534Gln, Arg506Gln, R506Q or rs6025! Since this amino acid is normally the cleavage site for aPC, the mutation prevents efficient inactivation of factor V. When factor V remains active, it facilitates overproduction of thrombin leading to excess fibrin ...
Genetic and environmental factors interact in determining the risk of venous thromboembolism (VTE). The risk associated with the polymorphic variants G1691A of factor V (Factor V Leiden, FVL), G20210A of prothrombin (PT20210A) and C677T of methylentetrahydrofolate reductase (C677T MTHFR) genes has been investigated in many studies. We performed a pooled analysis of case-control and cohort studies investigating in adults the association between each variant and VTE, published on Pubmed, Embase or Google through January 2010. Authors of eligible papers, were invited to provide all available individual data for the pooling. The Odds Ratio (OR) for first VTE associated with each variant, individually and combined with the others, were calculated with a random effect model, in heterozygotes and homozygotes (dominant model for FVL and PT20210A; recessive for C677T MTHFR). We analysed 31 databases, including 11,239 cases and 21,521 controls. No significant association with VTE was found for homozygous ...

Background: The rate of progression to cirrhosis varies among individuals chronically infected with the hepatitis C virus (HCV). Coagulation pathway activation in models of hepatic fibrosis suggests variation in coagulation pathway components may influence the rate of fibrosis. We hypothesised that polymorphisms of the coagulation factors II and V affect the rate of progression to cirrhosis in HCV infected subjects. Methods: We studied the relationship between rate of fibrosis (calculated by dividing the fibrosis stage by duration of infection) and genotypes of specific coagulation pathway genes in 352 White European patients infected with HCV. Genotyping was performed using reverse line blot hybridisation. Results: The rate of fibrosis was significantly higher in patients with the factor V Leiden genotype (Arg560Gln) (ANOVA, p=0.004). In disease association studies, o significant association was seen (Fishers exact test, p=0.029; odds ratio 3.28 for fast progression to cirrhosis (expected to reach
Factor V Leiden is not a disease, but a genetic mutation that results in thrombophilia, a blood clotting condition that increases a persons risk of developing abnormal blood clots in their blood vessels.
Factor V Leiden is not a disease, it is the presence of a particular gene that is passed on from your parents. We look how you can avoid blood clots.
Care should also be exercised in patients with Factor V (five) Leiden. This is a variation in a gene that affects the clotting process, increasing coagulation. Factor V Leiden is the most common inherited blood disorder in the United States. It is present in 4 to 6 percent of Caucasians; 2 percent of Hispanic Americans; a little over 1 percent of African Americans and Native Americans and about 0.5 of one percent of Asian Americans. Treatment is typically unwarranted unless there is evidence of a blood clot, in which case warfarin or other anticoagulants are prescribed. Depending on the situation, anticoagulants may be recommended to help afford advance protection against the development of blood clots. For example, women with a Factor V Leiden mutation may be advised to take anticoagulants during pregnancy and in the postpartum period.. ...

Uncovering common genetic risk factors for Parkinsons disease Introduction. Mutations in the so called PARK genes lead to rare familial forms of Parkinsons disease (PD). However the extent to which common genetic variability around these genes alters risk for common PD remains unclear. The Australian Parkinsons Project is analysing genetic variability around the PARK loci in a large PD case-control sample recruited from three Australian states. The emphasis is on gene-gene and gene-environment interactions between commonly occurring variables. Aim. To report on a pilot PD association analysis of 87 polymorphisms around13 PARK genes in an initial case-control sample recruited during 2006. Methods. PD cases (n=326) and unaffected control subjects (n=298) of white European ancestry were recruited from three specialist clinics in Brisbane and the Australian Electoral Roll. Common genetic variables (86 SNPs genotyped on the TaqMan platform and 1 STR variable genotyped using standard methods) were ...

The Role of APC-Resistance for Predicting Venous Thrombosis and Pregnancy Complications in Carriers of Factor V Leiden (1691) G/A Mutation. By Andrey Pavlovich Momot, Maria Gennadevna Nikolaeva, Valeriy Anatolevich Elykomov and Ksenia Andreevna Momot. This chapter presents the results of the prospective cohort study of 500 females with factor V Leiden, FVL, 1691 GA genotype, during 2008-2015. The association between FVL (regardless of its laboratory phenotype-factor Va resistance to activated protein C, APC resistance) and the development of VTEC (both outside of and during pregnancy) and gestational complications such as preeclampsia, fetal growth restriction, and miscarriage has been established. Additionally, the leading role of APC resistance degree in the clinical manifestation of FVL 1691 GA genotype as thrombotic events and pregnancy complications has been proved. Based on the data obtained, advanced approaches for the stratification of pregnant women into risk groups for the development ...

Synonyms for Factor V deficiency in Free Thesaurus. Antonyms for Factor V deficiency. 3 synonyms for factor V: accelerator factor, proaccelerin, prothrombin accelerator. What are synonyms for Factor V deficiency?
Factor V is a large (330 kilodalton) single-chain nonenzymatic cofactor that is synthesized in hepatocytes, megakaryocytes, and endothelial cells.6,7,9 Approximately 20% of the total factor V is carried in the α granules of platelets and is released when platelets are activated.6 The structure of factor V is similar to that of factor VIII.9 Factor Vs plasma concentration is 7 mg/mL and half-life is about 15 to 36 hours. Factor V activation occurs by both the extrinsic and intrinsic pathways. Factor V deficiency should be considered when a patient with bleeding history has both extended protime (PT) and activated partial thromboplastin time (aPTT). Congenital factor V deficiency, sometimes referred to as parahemophilia, is rare (less than one case per million individuals) and is inherited as an autosomal recessive trait.6,7,9 This condition affects both males and females and the prevalence of inherited factor V deficiency is equal in all ethnic groups.9 Factor V levels are decreased both in ...

We examined two sisters who had an ischaemic stroke at 32 and 41 years respectively. One had the prothrombin 20210 G to A variant1 and mild hyperhomocysteinaemia. The other had two prothrombotic mutations: the factor V Leiden mutation2 and the prothrombin 20210 G to A variant.1 We argue that these abnormalities may have caused the strokes.. Patient III-36 (pedigree, figure) was admitted at the age of 41 years with a left sided paresis. Her medical history was unremarkable, including the absence of migraine. Neurological examination showed a mild left sided paresis. Blood pressure was normal. She had no livedo reticularis. Brain CT showed a right sided cerebral infarct. Cardiological investigation, carotid angiography, and laboratory testing were normal, including investigation of antiphospholipid antibodies, lipid profile, fasting and post-methionine loading homocysteine concentrations, antithrombin III, protein C, and protein S. The patient was treated with aspirin and did not have arterial ...
Congenital causes of venous thrombosis have gained increasing prominence with the description of the factor V Leiden mutation and the prothrombin gene mutation. More recently, the description of the association between increased levels of coagulation factors and venous thrombosis and the finding that patients with thrombophilia can harbor more than one prothrombotic state have further increased the clinical relevance of the congenital thrombophilic states. In this qualitative review, we summarize current knowledge of the congenital prothrombotic states and propose a simple classification system that divides the states into two broad groups: those associated with reduced levels of the inhibitors of the coagulation cascade and those associated with increased levels or function of the coagulation factors. The first group is less common than the second, but it is associated with a much higher risk for venous thrombosis. This review provides clinicians with an evidence-based, practical guide to the ...
SUMMARY Thrombophilia refers to laboratory abnormalities that increase the risk of venous thromboembolism (VTE). Over the last several decades numerous factors have been identified. The most prevalent examples of hereditary forms of thrombophilia include the factor V Leiden and prothrombin G20210A mutations; deficiencies of the natural anticoagulants antithrombin, protein C, and protein S; persistently elevated levels of coagulation factor VIII; and mild hyperhomocysteinemia. Taken together, some form of hereditary thrombophilia can be identified in more than 50 percent of patients with VTE who are without obvious reasons for VTE, such as trauma or prolonged stasis. Moreover, hereditary thrombophilia has been associated with arterial cardiovascular disease and obstetric complications such as (recurrent) pregnancy loss and preeclampsia. The high yield of thrombophilia testing has led to widespread testing for these abnormalities in patients. Nevertheless, thrombophilia testing remains a topic of ...
Request Service. The venous thrombosis risk factor test will detect mutations in 3 different genes (Factor V, MTHFR and Prothrombin), all of which are aimed at determining an individuals risk for hypercoagulation.. Factor V Leiden: This Factor V gene mutation results in a Factor V protein that is resistant to cleavage by activated Protein C (aPC). It may be associated with as many as 50% of unexplained venous thromboses. By comparison, deficiencies of Antithrombin III, Protein S, and Protein C cumulatively account for only 15% of patients with hypercoagulable state. Patients heterozygous or homozygous for this mutation are respectively at 7 and 80 fold increased risk over the normal population of having venous thromboses.. Methylenetetrahydrofolate reductase polymorphism (A677V): This assay will detect a missense mutation (C to T) which results in the conversion of alanine to valine at position 677 of the MTHFR gene. This polymorphism has been implicated in venous thrombosis although risk ...

The variant causes elevated plasma prothrombin levels (hyperprothrombinemia),[4] possibly due to increased pre-mRNA stability.[5] Prothrombin is the precursor to thrombin, which plays a key role in causing blood to clot (blood coagulation). G20210A can thus contribute to a state of hypercoagulability, but not particularly with arterial thrombosis.[4] A 2006 meta-analysis showed only a 1.3-fold increased risk for coronary disease.[6] Deficiencies in the anticoagulants Protein C and Protein S further increase the risk five- to tenfold.[2] Behind non-O blood type[7] and factor V Leiden, prothrombin G20210A is one of the most common genetic risk factors for VTE.[4] Increased production of prothrombin heightens the risk of blood clotting. Moreover, individuals who carry the mutation can pass it on to their offspring.[8] The mutation increases the risk of developing deep vein thrombosis (DVT),[9] which can damage veins throughout the body, causing pain and swelling and sometimes leading to ...
In March 2006 I began experiencing pain in my right jaw and neck. An ultrasound of my thyroid showed a mild enlargement of my thyroid gland and thrombosis of the right internal jugular. A CT was ordered which showed bilateral segmental pulmonary emboli. A work up done to rule out cancer was negative however blood work showed a prothrombin gene mutation. At the time I was taking Yasmin. I was placed on Coumadin and told I should stay on this forever. I am worried that the risk of a bleed may now outweigh the need for anticoagulation since the thyroiditis is controlled and I am off oral contraceptives. Would it be wise to stop the Coumadin or is long-term use still recommended? Thank you ...

Despite the link between CTEPH and VTE, some classic plasmatic thromboembolic risk factors including antithrombin, protein C and protein S deficiency, and factor V Leiden mutation have been found not to be associated with CTEPH [5, 37]. However, elevated plasma concentrations of factor VIII, lupus anticoagulant and antiphospholipid antibodies, all three of which are risk factors for VTE, have been found to be associated with CTEPH [35, 37, 38]. Fibrinolytic factors have also been investigated, but have not been found to be significantly abnormal in patients with CTEPH [39]. Further nonplasmatic specific risk factors for VTE have also been identified as risk factors for CTEPH. Splenectomy, infected ventriculoatrial shunts, thyroid replacement therapy, malignancy and chronic inflammatory conditions, including osteomyelitis and inflammatory bowel disease, are all significantly associated with CTEPH and have a negative impact on prognosis [35, 40-42].. As with the other mechanisms involved in the ...

Washington, June 17 (ANI): A gene mutation can dramatically increase the risk of blood clots in women undergoing breast cancer therapy.In the study, researchers found that women taking tamoxifen for early-stage breast cancer who developed blood clots were more likely to carry a gene mutation for clotting than women taking tamoxifen who did not develop blood clots.Tamoxifen is a widely-used breast cancer treatment after surgery for pre and post menopausal patients with hormone receptor-positive breast cancer.One of the most serious complications of tamoxifen usage is the development of blood clots, or thromboembolic events (TEs).Previous studies have shown that use of tamoxifen increases the risk of TEs in healthy women twofold, and that in women aged 50 and above, it is associated with even greater risk.The genetic mutation Factor V Leiden (FVL) is the most common inherited clotting factor mutation and also causes increased thrombosis risk.To determine if having the Factor V Leiden genetic ...

The prothrombin gene variant resulting form a G--,A transition at position 20210 has been described as a common genetic risk factor for venous thrombosis. However, the risk for developing arterial disease is unknown. In this investigation, we studied 116 patients with venous thrombosis and 71 with arterial disease, all of whom were compared with 295 controls. Additionally, we also investigated the distribution of the prothrombin alleles among African descendents and Amazonian Indians from Brazil. The prevalence of 0.7% for 20210A allele in the control group increased to 4.3% (P = 0.021) among patients with venous thrombosis. There was also a high prevalence of the mutated allele in a selected arterial disease group (5.7%) without hyperlipoproteinemia, hypertension, and diabetes mellitus when compared to the controls (P = 0.013). Heterozygotes for the allele 20210A were common among individuals of African descent (2%) and rare among Indians. These data support the hypothesis that the prothrombin ...

John Pauls nosebleeds continue to be a problem. Hes seen our PCP (you rock yet again, Dr. LaSalle) a couple of times about this. She has recommended, and we have done, all the standard efforts to reduce his bloody nose frequency. They did become less frequent for awhile, then returned with a vengence in mid-January. Dr. LaSalle had recommened that if the frequency spead up again that we get a CBC (Complete Blood Count) to see if that gave us any clues. This, of course, was something I did not want to do. A blood draw is naturally terrifing for a 7 year-old. I also had an irrational fear that it would show he had leukemia (even though my leakemia is not hereditary. But doctors had told me that the chances of either of my children inheriting Factor V Leiden from me was slim to none, and that both getting was almost statistically improbable, and they both did). But after a four inch clot came out one morning, I threw in the towel and told myself to get a grip on my fears and do what needed to be ...
Venous thromboembolism (VTE) is a multifactorial disorder involving both acquired and genetic risk factors. The common genetic factors in Western populations have been studied and reported for several decades, while studies on Asian populations are relatively scarce. Evidence suggests that the prevalence and genetic risk factors of VTE vary significantly among ethnic populations. In this review, we summarize the common genetic risk factors of VTE in both Western and Asian populations. ...
