WebReduction of coagulation factors produced in the liver is a direct result of hepatocytic damage. While most clotting factors produced by the liver are dependent on vitamin K as well, levels of factor V (proaccelerin) and fibrinogen, which do not require this vitamin for synthesis, may also be low. WebThe clotting cascade involves different substances in addition to clotting factors. Factor X, which is produced (synthesized) in the liver, eventually interacts with other clotting factors and certain cells or substances, e.g. platelets or fibrinogen, to help to form a clot. Factor X deficiency is caused by a variation (mutation) in the F10 gene.
