WebAug 8, 2024 · Hemophilia B is an X-linked recessive bleeding disorder characterized by factor IX deficiency. This produces an intrinsic coagulation pathway defect and thus elevated PTT on laboratory studies. Patients are usually identified by family history or after evaluation for prolonged bleeding time with dental procedures or minor injury. WebFactor X is a vitamin K-dependent serine protease that is synthesized in the liver. Its biological half-life is 24 to 48 hours. Factor X participates in both intrinsic and extrinsic pathways of coagulation (final common pathway) by serving as the enzyme (factor Xa) in the prothrombinase complex.
