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 a results from a deficiency in clotting factor viii. In contrast, hemophilia b (also called christmas disease) is caused by a deficiency in clotting factor ix. Hemophilia a is more common than hemophilia b, and people with hemophilia a are more likely to suffer from severe disease. It would be impossible to distinguish the two on clinical presentation alone.
