Living with Gaucher disease type I

The most common form of Gaucher disease, usually affecting the spleen, liver, blood, and bones but not the brain.

Understanding Gaucher disease type I

Gaucher disease type 1 is the most common form of Gaucher disease, in which fatty cells build up in the spleen, liver, and bone marrow.

The body doesn't make enough of the enzyme glucocerebrosidase (GBA), which breaks down a fatty chemical. Unlike types 2 and 3, type 1 does not usually involve the brain and spinal cord. Symptoms range from mild to severe and may appear any time from childhood to adulthood. Diagnosis is confirmed by measuring GBA enzyme activity or with genetic testing.

Signs & symptoms

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

  • Enlarged spleen and liver
  • Low blood cell counts, including anemia and low platelets
  • Easy bruising and bleeding problems
  • Bone pain and bone disease
  • Fatigue and belly pain
  • Delayed puberty and slower growth

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 autoimmune and inflammatory disease specialists, bone and joint specialists, brain and nervous system specialists and eye disease specialists.

  3. Consider genetic testing

    Changes in GBA1 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  4. Connect with expert centers

    National Gaucher Foundation (NGF) and Children's Cardiomyopathy Foundation may keep lists of experts for this condition.
