Overview
Overview
Hemophilia B is a blood clotting disorder caused by a mutation of the Factor IX gene. It is the second most common form of haemophilia, rarer than haemophilia A. It is sometimes called Christmas disease after Stephen Christmas, the first patient described with this disease.[1] In addition, the first report of its identification was published in the Christmas edition of the British Medical Journal.[2]
