Glycogen storage disease type II (OMIM 232,300), also known as Pompe disease, is a severe, autosomal recessive, and progressive genetic condition caused due to mutations in the acid alpha-glucosidase (GAA) gene, thereby leading to a reduction in the activity of the GAA enzyme in the lysosomes [1, 2]. The gene discussed is GAA; the disease is Glycogen storage disease due to acid maltase deficiency.
