Definition: Pompe disease
is a genetic disorder involving a shortage of an enzyme called alpha-glucosidase, which causes a build-up of glycogen in cells. Particularly affected are the cells of the heart and the skeletal muscles, leading to cardiac and movement problems. There are two types of Pompe disease: infantile onset,
in which the enzyme is almost completely absent and the disease progresses quickly, usually resulting in death within the first year; and late onset,
which can be diagnosed in children or adults and progresses more slowly. The search for a cure for Pompe disease is the subject of the 2010 movie Extraordinary Measures.
