Hemophilia B*
A Factor IX (FIX) (or antihemophilic Factor B) deficiency or dysfunction leads to the hemophilia B disease, an hereditary or congenital coagulation disorder. FIX levels are reduced in patients receiving anti-vitamin K treatment, or in diseases such as liver disorders, cirrhosis or DIC. High FIX concentrations may be suggestive of an increased risk of venous thrombosis.
