Factor V Leiden (rs6025 or F5 p.R506Q [1]) is a variant (mutated form) of human factor V (one of several substances that helps blood clot), which causes an increase ...
The disorder was first described by Egeberg in 1965. [5] The causes of acquired antithrombin deficiency are easier to find than the hereditary deficiency. [3] The prevalence of antithrombin deficiency is estimated at ~0.02 to 0.2% of the general population, and 1-5% of patients with venous thromboembolism. [6]
[1] [5] This ratio is inversely related to the degree of APC resistance. [7] The ETP-based APC resistance test involves the addition of APC to a thrombin generation assay (TGA). [5] This results in an inhibition of thrombin generation as measured by reduction of the endogenous thrombin potential (ETP; area under the thrombin generation curve). [5]
APC resistance is the inability of protein C to cleave Factor Va and/or Factor VIIIa, which allows for longer duration of thrombin generation and may lead to a hypercoagulable state. This may be hereditary or acquired. [4] The best known and most common hereditary form is Factor V Leiden, which is responsible for more than 95% of cases. [5]

As such, family history of VTE is a risk factor for a first VTE. [88] Factor V Leiden, which makes factor V resistant to inactivation by activated protein C, [88] mildly increases VTE risk by about three times. [14] [88] Deficiencies of three proteins that normally prevent blood from clotting—protein C, protein S, and antithrombin ...
The minor ("type 2") thrombophilias are much more common. Factor V Leiden is present in 5% of the population of Northern European descent, but much rarer in those of Asian or African extraction. In people with thrombosis, 10% have factor V Leiden. In those who are referred for thrombophilia testing, 30–50% have the defect.
An anticoagulant, commonly known as a blood thinner, is a chemical substance that prevents or reduces the coagulation of blood, prolonging the clotting time. [1] Some occur naturally in blood-eating animals, such as leeches and mosquitoes, which help keep the bite area unclotted long enough for the animal to obtain blood.
