Description : Deficiency of all vitamin K-dependent clotting factors leads to a bleeding tendency
that is usually reversed by oral administration of vitamin K. Acquired forms of the
disorder can be caused by intestinal malabsorption of vitamin K. Familial multiple
coagulation factor deficiency is rare. Clinical symptoms of the disease include episodes
of intracranial hemorrhage in the first weeks of life, sometimes leading to a fatal
outcome. The pathomechanism is based on a reduced hepatic gamma-carboxylation of glutamic
acid residues of all vitamin K-dependent blood coagulation factors, as well as the
anticoagulant factors protein C (612283) and protein S (176880). Posttranslational
gamma-carboxylation of proteins enables the calcium-dependent attachment of the proteins
to the phospholipid bilayer of membranes, an essential prerequisite for blood coagulation.
Vitamin K1 acts as a cofactor for the vitamin K-dependent carboxylase in liver microsomes,
GGCX. - Genetic Heterogeneity of Combined Deficiency of Vitamin K-Dependent Clotting
Factors Combined deficiency of vitamin K-dependent clotting factors-2 (VKFCD2; 607473)
is caused by mutation in the gene encoding vitamin K epoxide reductase (VKORC1; 608547)
on chromosome 16p12-q21.;
