Mechanisms seem multifactorial with co-inheritance of Factor V Leiden mutation (FVL) with severe Hemophilia A (HA) being one of them. There is evidence that carrier ship of FVL mutation in CWH might confer an e
Coinheritance of a Factor V null allele occurs in approximately 1:1000 individuals heterozygous for Factor V Leiden. Rather than attenuating the effect of a Factor V Leiden allele, a coexisting Factor V deficiency enhances it, producing a more severe APC-resistant phenotype, reflected by an ...
Early epidemiologic data suggested that an abnormally low anticoagulant response to APC, termed "acti- vated protein C resistance (APC-R)," was familial, with an auto- somal dominant or semidominant inheritance pattern.7 Factor Va isolated from APC-R patient plasma was resistant to inactivation ...

The degree of associated bleeding worsens with lower residual factor levels, although the coinheritance of thrombophilic abnormalities (deficiencies of antithrombin, protein C, or protein S; Factor V Leiden; prothrombin gene mutation G20210A; and hyperhomocysteinemia) may occur and will moderate the ...
Keywords: Pediatrics, Lesch-Nyhan, Kidney stones, Allopurinol, Factor V Leiden Background Initially described in 1964, Lesch-Nyhan syndrome is characterized by a triad of hyperuricemia, central ner- vous system dysfunction, and familial inheritance and has an incidence of 1:100,000 to 1:300,000...
Inherited factor VII deficiency is a rare congenital coagulation disorder with autosomal recessive inheritance. Bilateral subdural hematomas, an unusual vaso-occlusive event and prolonged prothrombin time in a 58-year-old victim of an armed robbery In 20% (n=12) of the patients, a bleeding disorde...

A reduction in the level of FIX via reduction of thrombin generation reduces TAFI activation and increases fibrinolysis, whereas persistence of FVa (as is the case with co-inheritance of factor V [FV] Leiden) leads to increased (persistent) thrombin production and TAFI activation, thereby inhibitin...
