Haemophilia B is a blood disorder that prevents blood from clotting properly. This is a rare genetic disorder that is usually inherited. It is caused by a deficiency of Factor IX, a clotting protein.
Symptoms[edit]
The symptoms of Haemophilia B can vary greatly, depending on the severity of the disorder. Some of the most common symptoms include:
- Bleeding that is difficult to stop, even from minor wounds
- Frequent and unexplained nosebleeds
- Blood in the urine or stool
- Unusual bruising
- Joint pain and swelling
Causes[edit]
Haemophilia B is caused by a mutation in the F9 gene, which is responsible for producing Factor IX. This mutation can be inherited from a parent, or it can occur spontaneously.
Diagnosis[edit]
Diagnosis of Haemophilia B is usually made through a blood test that measures the level of Factor IX in the blood. Other tests may be used to rule out other conditions that can cause similar symptoms.
Treatment[edit]
Treatment for Haemophilia B typically involves replacing the missing Factor IX through infusions of a clotting factor concentrate. Other treatments may include medications to prevent blood clots, and physical therapy to manage joint damage.
