Living with Gaucher disease perinatal lethal

The earliest and most severe form of Gaucher disease, with signs around birth such as skin changes, an enlarged liver and spleen, and low blood counts.

Understanding Gaucher disease perinatal lethal

Gaucher disease perinatal lethal, also called fetal Gaucher disease, is the form of Gaucher disease that appears around birth.

It is an inherited metabolic condition that affects the newborn period and infancy. It can involve skin changes, an enlarged liver and spleen, low blood counts, low muscle tone, and joint stiffness. Decreased fetal movement may be noticed before birth.

Signs & symptoms

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

  • Enlarged liver and spleen
  • Dry, scaly skin (ichthyosis)
  • Low blood cell counts (pancytopenia)
  • Anemia and low platelet count
  • Low muscle tone (hypotonia)
  • Joints that can't be straightened (contractures)

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 genetic specialists and skin, hair, and nail 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

    Foundation for Ichthyosis and Related Skin Types may keep lists of experts for this condition.
