A person with a glycogen storage disease (GSD) has an absence or deficiency of one of the enzymes responsible for making or breaking down glycogen in the body. Symptoms often first appear in babies or young children. Glycogen storage disease type IV (Andersen disease) (OMIM 232500) and Adult Polyglucosan Body Disease (APBD) (OMIM 263570) are allelic disorders caused by a deficiency of the glycogen branching enzyme encoded by the GBE1 gene.
