Glycogen storage disease type II (MIM #232300), commonly known as Pompe disease (PD), is an autosomal recessive progressive neuromuscular disorder induced by a deficiency in lysosomal acid α-glucosidase (GAA, EC 3.2.1.20) [1,2,3,4,5,6]. Here, GAA is linked to Glycogen storage disease due to acid maltase deficiency.
