    Factor V Leiden / APC resistentie 1 op de 5 mensen is drager van Factor V Leiden. Hiervan krijgt een groot gedeelte nooit klachten. Wat is Factor V Leiden / APC resistentie? Factor V Leiden / APC resistentie (ongevoeligheid) is de meest voorkomende stollingsafwijking . Deze twee termen lijken verwarrend maar eigenlijk zijn het twee termen voor één afwijking. Kort samengevat: Door een defect op het vijfde gen (factor V) krijgt APC niet de kans zijn werk te doen. Met APC is niets mis, het gaat fout in Factor V.
    • Acht procent van de Nederlandse bevolking heeft een APC resistentie en heeft hierdoor een zes keer zo groot risico op trombose In combinatie met anticonceptie is dit risico zelfs veertig keer zo groot. Twintig tot veertig procent van mensen die een trombose hebben gehad hebben een APC resistentie / Factor V Leiden.
    Factor V is een van de twaalf stollingsfactoren die zijn vastgelegd in onze genen. Het zorgt ervoor dat het bloed stolt waar dat nodig is, bijvoorbeeld bij een wond. Factor V werkt samen met Factor X, maar maakt ook gebruik van proteïne C en proteïne S om de stolling op tijd te stoppen (het inactiveert / remt Factor V op het juiste moment). Net genoeg om de wond te dichten en net niet genoeg om stolsels te vormen. Andere " stollingsremmers " zijn

    Factor V Leiden Synoniem
    APC resistentie Korte beschrijving
    Factor V Leiden is een aangeboren en erfelijke bloedstollingziekte. Door Factor V Leiden blijft het bloed stollen. De factor V in het bloed is afwijkend. Daardoor kan het APC niet functioneren. APC betekent: geactiveerd Proteïne C. Het APC heeft een taak bij het stoppen van de bloedstolling. Als iemand een wondje heeft komt daar door bloedstolling een korstje op. Eerst vormt zich een voorlopig afdeklaagje. Aan dit afdeklaagje hechten zich stoffen, onder andere factor V. Factor V heeft de functie de bloedstolling te stoppen zodra het korstje stevig genoeg is. Maar bij ongevoeligheid voor APC (APC resistentie) reageert Factor V te langzaam op de werking van APC. Daardoor wordt het bloed te stolbaar. Stolseltjes kunnen vervolgens aangroeien en ergens in het lichaam een verstopping in de bloedbaan veroorzaken. Dit leidt tot trombose. Trombose komt vaak voor in de bloedvaten van de benen. Trombose kan ook op andere plaatsen in het lichaam voorkomen. Als het in de longen optreedt is er sprake van longembolie. Sommige situaties verhogen de kans dat Factor V Leiden opspeelt. Zoals het gebruik van de anticonceptiepil, zwangerschap, roken of te weinig bewegen.

    Gene-environment interactions ... On-line information Thrombophilia is the term used to refer to an inherited or acquired disorder of the haemostatic (blood clotting) system that causes an increased risk of venous thrombosis (blood clots in the veins). Examples of venous thrombosis include DVT (deep vein thrombosis) of the limbs or pulmonary embolism; these conditions are sometimes grouped together as venous thromboembolism, or VTE. The incidence of VTE in the general populations of Western countries is around 1-3 per 1000 individuals. Treatment of venous thromboembolism uses anti-coagulants, typically heparin in the acute phase of VTE followed by a period of treatment with coumadin to prevent further VTEs. Long-term management of patients who have experienced thrombosis includes avoidance of risk factors that make thromboembolism more likely, and the use of prophylactic (preventative) anti-coagulant therapy in situations where risk is known to be increased, for instance during surgery.
    Genetics
    Factor V (Leiden) thrombophilia Inherited thrombophilia is a genetically determined predisposition to venous thromboembolism, and may be caused by a number of known mutations. Factor V Leiden is the most common form of hereditary thrombophilia in the UK. Between 3 and 7% of the Caucasian population have a single copy of the mutant Factor V Leiden gene (

The result is a long-lived Factor Va and a hypercoaguable state. The clinical name for this condition is Activate Protein C resistance (APCR), which is the most common inherited risk factor in venous thrombosis. Heterozygosity for this mutation is associated with a 5 to 10-fold increased risk of developing a venous thrombitic episode while homozygosity for this mutation is associated with a 50 to 100-fold increased risk. Factor V Leiden is associated with the following complications: venous thrombosis (blood clots, especially with oral contraceptives); deep vein thrombosis (DVT, blood clots in veins); unexplained miscarriage; blood clots in the lungs or anywhere else; gall bladder dysfunction; preeclampsia and/or eclampsia (toxemia while pregnant); and stroke and/or heart attack.

    Resistance to activated protein C due to Factor V R506Q (Factor V Leiden)
    David Keeling BSc MD MRCP MRCPath Consultant Haematologist Oxford Haemophilia Centre, Churchill Hospital, Oxford.
    The Discovery of Resistance to Activated Protein C and Identification of the Mechanism.
    The phenomenon of resistance to activated protein C (APC) was discovered only three years ago. Dahlback and colleagues identified a middle aged man with a personal and a family history of thrombosis whose APTT did not show the expected prolongation when exogenous APC was added to his plasma [1]. The same phenomenon was found in several of the patient's relatives. The mechanism was unknown but inheritance of a deficiency of a cofactor for APC was hypothesised. This proved not to be the case and one year later the molecular defect was identified as a point mutation in factor V (FV) [2]. The mutation was a G to A substitution at nucleotide position 1,691. This results in the arginine at position 506 (coding triplet CGA) being replaced by a glutamine (coding triplet CAA). Using the single letter amino-acid code the mutant FV can therefore be written as FV R506Q but is more often referred to as FV Leiden (Figure 1).
    Figure 1. The G to A point mutation results in the arginine at the protein C cleavage site being replaced by glutamine.

    (Factor V Leiden Mutation)
    General Information:
    The Factor V Leiden mutation (R560Q) is present in 20-40% of patients with venous thrombosis, 40-65% of adults from families with unexplained thrombophilia, and approximately 95-100% of patients with the phenotype of activated protein C (APC) resistance. The Factor V Leiden mutation is a significant risk factor for venous thrombosis, particularly in the homozygous state or in combination with additional risk factors such as pregnancy, use of oral contraceptives or surgery. Methodology: This test includes preparation of DNA from peripheral blood and PCR based analysis for direct detection of the common Factor V Leiden mutation (R506Q). PCR is performed pursuant to a license agreement with Roche Molecular Systems, Inc. Use: Identification of individuals heterozygous or homozygous for the Factor V Leiden mutation. Indications: Venous thrombosis or history of a thrombotic event, activated protein C resistance by laboratory analysis, presence of another hereditary coagulation disorder (protein C deficiency, protein S or antithrombin III), family history of thrombosis or known Factor V Leiden mutation. V Leiden mutation. Specimen Requirements: Please see Instructions for Shipping and Handling Specimens Turnaround Time: 3-7 days (time required for culture of tissue specimens not included.) Cases are prioritized on an individual basis.
