Learning About Pompe Disease

Pompe disease is a rare inherited neuromuscular disorder that causes progressive muscle weakness in people of all ages. The disease is named after Johannes C. Pompe, a Dutch doctor who first described the disorder in 1932 in an infant patient.[1], [2] However, Pompe can affect people of all ages, with symptoms first occurring at any time from infancy to adulthood.[1]

Pompe disease is caused by a defective gene that results in a deficiency of an enzyme, acid alpha-glucosidase (pronounced “AL-fa glue-CO-sih-days” and often abbreviated GAA). The absence of this enzyme results in excessive buildup of a substance called glycogen, a form of sugar that is stored in a specialized compartment of muscle cells throughout the body.
