Living with Congenital dyserythropoietic anemia

A rare group of inherited blood conditions in which red blood cells do not mature normally, causing anemia and tiredness.

Understanding Congenital dyserythropoietic anemia

Congenital dyserythropoietic anemia (CDA) is a rare group of inherited blood disorders that affect how red blood cells develop.

Immature red blood cells do not become normal, mature cells, so there are fewer working red blood cells. Anemia is usually mild to moderate, but can be severe enough to need frequent transfusions. The body can also absorb too much iron. There are several types, each with a different genetic cause. It often starts in childhood.

Signs & symptoms

Symptoms vary from person to person. GARD's summary lists these:

  • Tiredness (fatigue)
  • Weakness
  • Yellow skin and eyes (jaundice)
  • Enlarged liver and spleen
  • Too much iron in the body (iron overload)
  • Gallstones in type II

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include blood and bone marrow specialists and genetic specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
