Living with Diamond-Blackfan anemia

A condition of the bone marrow that makes too few red blood cells, usually found in the first year of life.

Understanding Diamond-Blackfan anemia

Diamond-Blackfan anemia is a condition that mainly affects the bone marrow, which does not make enough red blood cells.

Red blood cells carry oxygen. The shortage (anemia) usually shows in the first year of life. Many people also have physical differences in parts of the body. People have a higher chance of myelodysplastic syndrome, acute myeloid leukemia, osteosarcoma, and other cancers.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Anemia (too few red blood cells)
  • Tiredness (lethargy)
  • Pale skin (pallor)
  • Slow growth
  • Large red blood cells
  • Head and facial differences

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, brain and nervous system specialists, cancer specialists and ear, nose, and throat specialists.

  3. Ask which tests can help

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

  4. Connect with expert centers

    World Craniofacial Foundation may keep lists of experts for this condition.
