Glycogen storage disease type II

Patent Granted Glycogen storage disease type II (also called Pompe disease /ˈpɒmpə/ or acid maltase deficiency) is an autosomal recessive metabolic disorder[1] which damages muscle and nerve cells throughout the body. It is caused by an accumulation of glycogen in the lysosome due to deficiency of the lysosomal acid alpha-glucosidase enzyme. It is the only glycogen storage disease with a defect in lysosomal metabolism, and the first glycogen storage disease to be identified, in 1932 by the Dutch pathologist J.C.Pompe.
