Women with hemophilia B

Women with a defective factor IX gene are carriers of hemophilia B. There may be five times as many carriers as there are men with hemophilia, and at least one-third of carriers have factor levels below the normal range. A significant number of them have bleeding problems. Lack of recognition of an obvious condition can make it difficult for women with hemophilia to be taken seriously about their disease
