CDA is usually diagnosed in children but sometimes it can be diagnosed in babies or even in adults.
In CDA, the bone marrow tries very hard to make red blood cells but these cells don’t work properly.
Patients can be treated with interferon injections or blood transfusions, but often don’t need any specific treatment for the anaemia.
Iron overload is a big problem in CDA, even if patients are not receiving blood transfusions. People with CDA can sometimes have other changes in their bodies. These are usually minor and can affect the hands and feet.
