Based on these findings, Stbd1 was considered an attractive target for therapy for Pompe disease (glycogen storage disease type II; OMIM #232300), a severe metabolic myopathy characterized by the intralysosomal accumulation of glycogen due to the inherited deficiency of the enzyme acid α-glucosidase (GAA) (Chen et al., 2009). The gene discussed is STBD1; the disease is Glycogen storage disease due to acid maltase deficiency.
