Disease characteristics

Excerpted from the GeneReview: Factor V Leiden Thrombophilia
Factor V Leiden thrombophilia is characterized by venous thromboembolism (VTE) manifesting most commonly in adults as deep vein thrombosis (DVT) in the legs or pulmonary embolism. Thrombosis in unusual locations is less common. Factors that predispose to VTE in factor V Leiden thrombophilia include: the number of factor V Leiden variant alleles (homozygotes have a much greater thrombotic risk); family history of VTE; presence of coexisting genetic thrombophilic disorders; acquired thrombophilic disorders (e.g., antiphospholipid antibody syndrome, paroxysmal nocturnal hemoglobinuria, myeloproliferative disorders); and circumstantial risk factors (e.g., pregnancy, malignancy, central venous catheters, travel, combined oral contraceptive use and other combined contraceptives, oral hormone replacement therapy [HRT], obesity, leg injury, and advancing age). [from GeneReviews]

Additional descriptions

From OMIM
Thrombophilia due to activated protein C resistance is due to a mutation in the F5 gene that renders factor V resistant to cleavage and inactivation by activated protein C (PROC; 612283) and results in a tendency to thrombosis. See also factor V deficiency (227400), an allelic disorder resulting in a hemorrhagic diathesis due to lack of factor V. The most common mutation that causes this disorder is referred to as factor V Leiden (R506Q; 612309.0001), named after the town in the Netherlands where Bertina et al. (1994) discovered the defect. Homozygosity increases the risk of thrombotic complications to a greater extent than heterozygosity. However, heterozygous presence of the mutation may be combined with defects in other genes in the clotting pathway to contribute to the disorder. Expressivity is variable and influenced by environment.  http://www.omim.org/entry/188055
From MedlinePlus Genetics
Factor V Leiden thrombophilia is an inherited disorder of blood clotting. Factor V Leiden is the name of a specific gene mutation that results in thrombophilia, which is an increased tendency to form abnormal blood clots that can block blood vessels.

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). DVTs occur most often in the legs, although they can also occur in other parts of the body, including the brain, eyes, liver, and kidneys. Factor V Leiden thrombophilia also increases the risk that clots will break away from their original site and travel through the bloodstream. These clots can lodge in the lungs, where they are known as pulmonary emboli. Although factor V Leiden thrombophilia increases the risk of blood clots, only about 10 percent of individuals with the factor V Leiden mutation ever develop abnormal clots.

The factor V Leiden mutation is associated with a slightly increased risk of pregnancy loss (miscarriage). Women with this mutation are two to three times more likely to have multiple (recurrent) miscarriages or a pregnancy loss during the second or third trimester. Some research suggests that the factor V Leiden mutation may also increase the risk of other complications during pregnancy, including pregnancy-induced high blood pressure (preeclampsia), slow fetal growth, and early separation of the placenta from the uterine wall (placental abruption). However, the association between the factor V Leiden mutation and these complications has not been confirmed. Most women with factor V Leiden thrombophilia have normal pregnancies.  https://medlineplus.gov/genetics/condition/factor-v-leiden-thrombophilia

Clinical features

From HPO
Deep venous thrombosis
MedGen UID:
57448
Concept ID:
C0149871
Disease or Syndrome
Formation of a blot clot in a deep vein. The clot often blocks blood flow, causing swelling and pain. The deep veins of the leg are most often affected.
Prolonged partial thromboplastin time
MedGen UID:
66815
Concept ID:
C0240671
Finding
Increased time to coagulation in the partial thromboplastin time (PTT) test, a measure of the intrinsic and common coagulation pathways. Phospholipid, and activator, and calcium are mixed into an anticoagulated plasma sample, and the time is measured until a thrombus forms.
Thrombophilia
MedGen UID:
98306
Concept ID:
C0398623
Disease or Syndrome
An abnormality of coagulation associated with an increased risk of thrombosis.
Resistance to activated protein C
MedGen UID:
109068
Concept ID:
C0600433
Disease or Syndrome
Poor anticoagulant response to activated protein C. A plasma is termed 'APC resistant' when the addition of exogenous APC fails to prolong its clotting time in an activated partial thromboplastin time assay.
