Haemophilia B (or hemophilia B) is a blood clotting disorder caused by a mutation of the factor IX gene, leading to a deficiency of factor IX. It is the second-most common form of haemophilia, rarer than haemophilia A. It is sometimes called Christmas disease, named after Stephen Christmas, the first patient described with this disease.
Hemophilia is an X-linked inherited bleeding disorder caused by mutation of the F8 gene that encodes for coagulation factor VIII or the F9 gene that encodes for coagulation factor IX. The degree of plasma factor deficiency correlates with both the clinical severity of disease and genetic findings.
