Glycogen storage disease of heart (GSDH) is an autosomal dominant disorder of glycogen metabolism. This disease is caused by mutations in the PRKAG2 gene, which encodes gamma-2 subunit of AMPK. It is characterized by fatal infantile cardiomyopathy, often associated with apparent phosphorylase b kinase deficiency.
