CPN | GM-1


Gangliosidosis (GM-1) is an inherited lysosomal storage disease that progressively destroys neurons (nerve cells) in the brain and spinal cord. The signs and symptoms of the most severe form of GM1 gangliosidosis, called Type I or the infantile form, usually become apparent by the age of six months. Affected infants typically appear normal until onset, but developmental regression (loss of acquired milestones) eventually occurs, and muscles used for movement weaken.

There is currently no effective medical treatment for GM-1, and affected children have a shortened life expectancy. Symptom management and supportive treatments often focus on nutrition, hydration, and respiratory care.
