The coexistence of homozygous factor V Leiden mutation and antiphospholipid antibodies in patients with Budd-Chiari syndrome is extremely rare. In contrast to prothrombin G20210A, FVL leads to an increased resistance of factor V to inhibition by protein C, thereby creating a hypercoagulable state. TIA! Activated Protein C (APC) is a regulator of the coagulation cascade, by specifically inactivating factors Va and VIIIa, in the presence of phospholipids and calcium.. Most people with factor V Leiden thrombophilia have one "normal" F5 gene and one with the factor V Leiden gene mutation. Women who are heterozygous and especially homozygous for the factor V Leiden mutation have a greater thrombotic risk when using any HC preparation.

This Remarkably, the only patient homozygous for the factor V Leiden mutation—who was also heterozygous for the 5,10-MTHFR gene mutation—suffered from clinically manifest cerebrovascular, cardiovascular, and peripheral arterial disease already at the age of 52 years, but, on the other hand, his history was free of venous thrombotic events. Factor V Leiden (FVL) is an autosomal-dominant inherited thrombophilia. Factor V Leiden (FVL) refers to the specific G-to-A transition at nucleotide 1601 (c.1601G>A) in exon 10 of the factor V gene, which results in arginine to glutamine substitution at amino acid 534 of the protein (p.Arg534Gln), previously known as p.Arg506Gln. Factor V Leiden (FVL) is a 20,000-year-old mutation common in the general population and a major genetic risk factor for thrombosis. The prevalence of these 2 mutations is known to show a distinct world distribution and is most prevalent among Caucasians. The brothers or sisters of this person might have: Inheriting Factor V Leiden If you inherit Factor V Leiden from one parent, this is known as heterozygous Factor V Leiden.
