Also called: Classic hemophilia, Factor VIII deficiency, Christmas disease, Factor IX deficiency
Hemophilia is a rare bleeding disorder in which the blood does not clot properly. A person with hemophilia may bleed longer after an injury or may bleed internally. The disorder can be mild, moderate, or severe. In some cases, it may be life-threatening.
Hemophilia is caused by low or missing clotting factor. Clotting factors are proteins in the blood needed for normal blood clotting. The type of hemophilia a person has depends on which clotting factor is affected.
Types of hemophilia include:
Hemophilia usually occurs due to a gene change (mutation) that is inherited (passed down in families). Sometimes the mutation is a new gene change. The disorder most often affects males.
Hemophilia is a lifelong disorder. There is no cure. But most people with hemophilia have a normal life expectancy. With the right treatment and self-care, a person with hemophilia can live a healthy, active life.

This study will help researchers understand how hemophilia affects how patients think, feel, and experience school.
Age:
6 to 18 years old
Study goal:
To find out how much patients with hemophilia B, their caregivers, and health care workers know about gene therapy for this disease, and how they feel about gene therapy. This will help us better educate patients and caregivers about gene therapy for hemophilia B.
Age:
