Prothrombin (factor II) deficiency is an autosomal recessive disorder associated with moderate or severe bleeding tendency. It occurs in approximately 1 in 1-2 million people. Prothrombin is activated to thrombin, which in turn proteolytically cleaves fibrinogen to fibrin and contributes to forming a stable fibrin clot.
