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 or sex linked inherited disorder which means that the defect is carried on the X chromosome. Females have two X chromosomes and males have one X chromosome and one Y chromosome. The X chromosome, which carries the hemophilia gene in males, causes Factor VIII or Factor IX to be missing or deficient (low level). Each child of a hemophilia carrier has a 50% chance of being affected by hemophilia; either having hemophilia for a male or being a carrier for a female.
