Short answer

**Aase syndrome can be serious, especially when anemia is severe or heart defects are present.**

This rare condition, considered part of Diamond-Blackfan anemia, affects red blood cell production and can involve bone and joint differences. Your outlook depends on the severity of anemia, associated health problems, and response to treatment. Anemia often improves with age, but ongoing care remains important because some complications, including certain cancers, are more common. If you or your child has this diagnosis, keep scheduled blood tests and specialist visits, and report new fatigue or unusual paleness.

Common questions

Is Aase syndrome serious?

Aase syndrome can be serious because the bone marrow makes too few red blood cells, causing anemia that limits oxygen delivery. It can also involve heart defects and bone or joint differences. Severity varies, and anemia often improves with age. Treatment may include blood transfusions, prescribed steroids, or a bone marrow transplant when other treatments fail. If you or your child has Aase syndrome, a blood specialist needs to assess severity and arrange ongoing monitoring. Call 911 for severe trouble breathing or loss of consciousness.
