A hereditary disorder of blood coagulation which can only be distinguished from haemophilia by laboratory tests. It is so-called after the surname of the first case reported in this country. About one in every ten patients clinically diagnosed as haemophiliac has in fact Christmas disease. It is due to lack in the blood of Factor IX.
A form of hemophilia in males resulting from Factor IX deficiency.
