Final answer:
Hemophilia B is a clotting disorder that results from an inadequate amount of factor IX. It is a genetic disorder that causes excessive bleeding from minor wounds and other symptoms. Treatment involves regular infusions of clotting factors.
Step-by-step explanation:
Hemophilia B is a clotting disorder that results from an inadequate amount of factor IX, also known as the Christmas factor. It is a genetic disorder in which there is a deficiency of factor IX, which is responsible for blood clotting. Hemophilia B is passed from a carrier mother to her male offspring, as it is linked to the X chromosome. Patients with hemophilia B experience excessive bleeding from minor wounds and may also bleed into joint spaces after exercise or into urine and stool.
Treatment for hemophilia B involves regular infusions of clotting factors isolated from healthy donors to prevent bleeding. In the future, genetic therapy may also become a viable option for managing the disorder.
