Living with GM1 gangliosidosis type 2

The juvenile form of GM1 gangliosidosis, an inherited condition that gradually damages nerve cells in the brain and spinal cord, noticed in childhood.

Understanding GM1 gangliosidosis type 2

GM1 gangliosidosis type 2 is the juvenile form of an inherited lysosomal storage disorder that progressively destroys nerve cells.

GM1 gangliosidosis is grouped into three types by age of onset: classic infantile (type 1), juvenile (type 2), and adult or chronic (type 3). The types differ in severity but their features overlap a lot. Type 2 is usually noticed in childhood.

Signs & symptoms

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

  • Unsteady walk
  • Low muscle tone (hypotonia)
  • Loss of motor skills
  • Enlarged liver
  • Coarse facial features and enlarged gums
  • Joint stiffness and bone 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 bone and joint specialists, brain and nervous system specialists, eye disease specialists and genetic specialists.

  3. Consider genetic testing

    Changes in GLB1 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

    Epilepsy Foundation may keep lists of experts for this condition.
