This article will review the factor V Leiden mutation, its association with VTE, and the genetic inheritance pattern and ethnic distribution. Oral contraceptive use, pregnancy, and hormone replacement therapy in women with the Leiden mutation will be discussed. Screening issues and management for all...

prevalence of 50% (4 of 8 patients) and a relative risk of venous thrombosis in IBD patients with factor V Leiden of 23 (95% confidence interval, 2-294; P = 0.005).In patients with IBD, inheritance of the factor V Leiden mutation results in a significant increased risk of venous ...

Testing The diagnosis of Factor V Leiden requires the APC resis- tance assay, a coagulation screening test, or DNA analysis of F5, the gene encoding Factor V, to identify the Leiden mutation, a specific G-to-A substitution at nucleotide 1691 that predicts a single-amino acid replacement (R...

Factor II c.*97G>A Mutation Double-homozygosity 1. Introduction Factor V Leiden [FVL (c.1601G > A, R534Q)] and factor II (FII) c.*97G > A mutation are the two most common genetic factors predisposing to hereditary thrombophilia [1]. Both mutations exhibit a codominant trait pattern ...
Factor V Leiden mutation: a treatable etiology for sporadic and recurrent pregnancy loss We hypothesized that the thrombophilic G1691A factor V Leiden (FVL) gene mutation was a common, significant, and treatable cause of sporadic and recurrent ... CJ Glueck,S Gogenini,J Munjal,... - 《Ferti...
The aim of this study was to determine the frequency of FV Leiden and coinheritance of FV Leiden with two other frequent hereditary thrombophilia causes, namely, prothrombin G20210A and methylene-tetrahydrofolate reductase (MTHFR) C677T mutation in the Aegean region of Turkey. The study ...
FV/PT 2.4 Mode of inheritance. Both the factor V Leiden mutation and the prothrombin 20210GϾA mutation exhibit semidominant expression in that both heterozygotes and ho- mozygotes are at increased risk of occurrence/recurrence of venous thrombosis. The relative risk for venous thrombosis ...
