About the disease
Pompe disease, also known as glycogen storage disease type II, acid maltase deficiency disease, and acid maltase deficiency disease, is a genetic disorder in which glycogen builds up in organs and tissues, especially in muscles, causing them to break down. It is a rare disease that affects multiple body systems. Subtypes include: classic form of infantile-onset Pompe disease, non-classic form of infantile-onset Pompe disease, and late-onset type of Pompe disease.
