Living with Acquired hemoglobin H disease

A blood condition in adults that combines a bone marrow disorder with a type of anemia called hemoglobin H disease.

Understanding Acquired hemoglobin H disease

Acquired hemoglobin H disease is an acquired form of alpha-thalassemia linked to a bone marrow disorder.

It occurs with a myelodysplastic syndrome (MDS), or more rarely a myeloproliferative disease, along with hemoglobin H disease. People can have anemia, easy bruising and bleeding, and tiredness. GARD lists onset as adult.

Signs & symptoms

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

  • Anemia with small red blood cells
  • Fatigue
  • Easy bruising and bleeding
  • Low platelet count
  • Low neutrophil count
  • Shortness of breath

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. Consider genetic testing

    Changes in ATRX are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
