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 is the most common type of hemophilia, and itâs caused by a deficiency in factor VIII. According to the National Heart, Lung, and Blood Institute (NHLBI), eight out of 10 people with hemophilia have hemophilia A. Hemophilia B, which is also called Christmas disease, is caused by a deficiency of factor IX.
