Thrombophilia – Factor V (F5) Gene Mutations

Thrombophilia refers to a predisposition to developing thrombosis. Thrombosis is a pathological process where a blood clot forms within a blood vessel. When the clot forms in an artery, it is called arterial thrombosis; when it forms in a vein, it is known as venous thrombosis. The most common sites for venous thrombosis are the veins of the lower limbs and pelvis. Clots in the coronary artery can lead to heart attacks. Thrombosis may be inherited or acquired.

Causes of Acquired Thrombophilia:

• Antiphospholipid syndrome
• Systemic lupus erythematosus
• Rheumatoid arthritis
• Dermatomyositis
• Infections and inflammatory conditions: ulcerative colitis, Crohn's disease
• Cancers and chemotherapy: leukemia, lymphoma, colorectal cancer, lung cancer

Causes of Inherited Thrombophilia:

• Factor V (F5) gene mutations
• Factor II (prothrombin) (F2) gene mutations
• Deficiency of coagulation inhibitors caused by gene mutations: antithrombin (SERPINC1 gene mutation), protein C (PROC gene mutation), and protein S (PROS1 gene mutation). Antithrombin (AT), protein C (PC), and protein S (PS) are endogenous inhibitors of the coagulation process
• Polymorphisms in the MTHFR (methylenetetrahydrofolate reductase) gene
• Polymorphisms in the PAI-1 (plasminogen activator inhibitor-1) gene

Common Symptoms of Thrombosis:

• Asymmetrically swollen limbs
• Cyanosis of the feet and lower legs
• Pain while walking
• Pain and redness at the site of swelling
• Dilated blood vessels
• Rapid heartbeat
• Chest pain

Purpose of the Test:

• Identification of mutations in the Factor V (F5) gene in the patient's genetic material, commonly known as the Leiden V mutation.

This Mutation:

• Is the most common cause of inherited thrombophilia, occurring in 3-7% of the general population
• Increases the risk of venous and arterial thrombosis, heart attacks, and strokes
• Is one of the causes of recurrent miscarriages

Indications for Testing:

• Symptoms of thromboembolic disease
• Family history of thrombophilia
• Previous thrombotic episodes
• Surgical procedures requiring prolonged immobilization
• Recurrent miscarriages or stillbirths
• Use of hormonal contraception
• Hormone replacement therapy
• Thrombocytopenia
• Cancer
• Sedentary lifestyle
• Obesity

Method:

• Real-time PCR
• High sensitivity of the test – 99%

Sample for Testing:

• EDTA blood
• Oral swab

Turnaround Time:

• Up to 7 business days

Instructions for sampling are included in the package.
