Hemophilia B, or Christmas disease, is an inherited, recessive disorder that involves deficiency of functional coagulation factor IX (FIX) in plasma. Hemophilia B is caused by a variety of defects in the F9 gene. [1] As this gene is carried on the X chromosome, the disease usually manifest...
The meaning of HEMOPHILIA is a hereditary, sex-linked blood defect occurring almost exclusively in males that is marked by delayed clotting of the blood with prolonged or excessive internal or external bleeding after injury or surgery and in severe cases
Factor IXHemophilia BProphylaxisTreatmentThe biology of factor IX deficiency leading to hemophilia B has important distinctions from factor VIII deficiency that leads to hemophilia A. In this article, the authors explore the unique biology of factor IX in hemostasis, including the importance of FIX ...
Hemophilia A is due to a deficiency in factor VIII and is about four times as common as hemophilia B, which is due to a deficiency of factor IX. Hemophilia is typically inherited, meaning that it’s passed through the parents’ genes or DNA, although approximately one-third of cases are ...

The amount of your clotting factor may also need to be increased before you have dental work. Talk with your provider before you have any dental work. Ask about vaccines you may need. Ask your provider if you should get vaccines against hepatitis A or B, or other infections. Your provider...
Factor IX (FIX) deficiency or dysfunction, or hemophilia B, is an X-linked inherited bleeding disorder, usually manifested in males and transmitted by females who carry the causative mutation on the X chromosome. Hemophilia B results from a variety of defects in the FIX gene. FIX deficiency is...

What are the symptoms of hemophilia A and B? Hemophilia can vary in severity, depending upon the particular type of mutation (genetic defect). The degree of symptoms depends upon the levels of the affected clotting factor. Severe disease is defined as <1% factor activity, 1% to 5% factor ac...
