Accordingly, the activated form of mutated factor V (FVa:Q506) is more slowly degraded by activated protein C than normal FVa (FVa:R506) is, resulting in hypercoagulability and a lifelong 5- to 10-fold increased risk of venous thrombosis.

Factor V is an important blood coagulation factor, the procoagulatory activity of which is inhibited by activated protein C. The factor V Leiden mutation is due to a single base-pair change (G1691A), which alters the initial cleavage site for activated protein C. The impaired degradation of factor V by activated protein C yields a hypercoagulable state that confers a lifelong increased risk of thrombosis in heterozygous and homozygous individuals.

It was recently found that aPL may cause the acquired activated protein C resistance phenotype, whereas in familial thrombophilia, activated protein C resistance frequently results from a point mutation in the factor V gene (replacing arginine 506 with a glutamine) that leads into the (R-506-Q), the so-called Leiden mutation, that produces a mutated factor V, resistant to the catalytic action of activated protein C, otherwise normal in its procoagulant properties.
