Theoretical considerations The factor V Leiden (FVL) mutation is the most prevalent inheritable risk factor for venous thromboembolism (VTE) 1. Heterozygous carriers of FVL have an approximately 3-to 5-fold increased risk of VTE, whereas the risk in homozygous carriers is estimated to be up to ...
We report an 81-year-old female with a heterozygous factor V Leiden mutation who developed purpura fulminans. Digital necrosis, a characteristic clinical feature of purpura fulminans was prominent. Purpura fulminans is more common in children and adult cases are rare. Of eight reported cases of ...

Methods: We consecutively enrolled patients under 45 years of age, with less than 3 CVRF, evaluated for VTE or ATE, women and men as a comparator. The control group consisted of healthy young women. A thrombophilia panel and genetic testing for Factor V Leiden (FVL), G20210A Prothrombin ...
For example, the concurrent use of a panel of three genetic tests (factor V Leiden, prothrombin variant G20210A, and protein C deficiency) increases the positive predictive value of testing for venous thrombosis at least eightfold. Multiplex genetic testing has the potential to improve the ...

similar to that among patients with no known mutations in either factor II or factor V (relative risk, 1.1), patients who were heterozygous for both factor V Leiden and prothrombin 20210GϾA had a 2.6- fold higher risk of recurrent thrombosis than did carriers of factor V Leiden alone. ...
For Factor V Leiden genetic testing for recurrent pregnancy loss, see CPB 0348 - Recurrent Pregnany Loss. Footnote11++The requirement to have an abnormal activated protein C (APC) resistance assay result is waived if the member is on direct oral anticoagulants (e.g., apixaban [Eliquis], dabi...
results for the inherited thrombophilias.We reviewed the literature focusing on case-control studies of the 5 most commonly inherited disorders of coagulation: protein C deficiency, protein S deficiency, antithrombin deficiency, and the factor V Leiden and prothrombin gene mutations in patients with ...
