Type – II Glycogenosis (Pompe’s
Disease)

• It is a fatal type, caused by deficiency of a lysosomal
enzyme glucosidase (acid maltase), whose function is
to degrade glycogen in the cell.

• People with Pompe’s disease cannot produce the
enzyme acid alpha-glucosidase, or GAA gene in
lysosomes.

• Glycogen accumulates in lysosomes of tissues,
especially the heart, leading to cardiomegaly, heart
failure and death.
