Coagulation factor XII

The F12 gene encodes coagulation factor 12. Activated factor 12 is a serin protease that has a function in initiation the coagulation cascade, fibrinolysis, and activation of bradykinin and angiotensin. Mutations cause autosomal domimant and recessive factor XII deficiency and dominant hereditary agioedema type 3.
