Hemophilia B is caused by the deficiency of Factor IX. It is also known
as Christmas disease. It occurs in 1 in 100,000 male births. It has to
be diagnosed accurately because clinically it is indistinguishable from
factor VIII deficiency - Hemophilia A.

of six proteins synthesized in the liver that require vitamin K for
