Overview
Glycogen storage disease (synonyms: glycogenosis, dextrinosis) is any one of several inborn errors of metabolism that result from enzyme defects that affect the processing of glycogen synthesis or breakdown within muscles, liver, and other cell types.
Types
There are nine diseases that are commonly considered to be glycogen storage diseases. (Although glycogen synthase deficiency does not result in storage of extra glycogen in the liver, it is often classified with the GSDs as type 0 because it is another defect of glycogen storage and can cause similar problems.)
Number | Enzyme deficiency | Eponym |
GSD type I | glucose-6-phosphatase | von Gierke's disease |
GSD type II | acid maltase | Pompe's disease |
GSD type III | glycogen debrancher | Cori's disease or Forbe's disease |
GSD type IV | glycogen branching enzyme | Andersen disease |
GSD type V | muscle glycogen phosphorylase | McArdle disease |
GSD type VI | liver glycogen phosphorylase | Hers' disease |
GSD type VII | muscle phosphofructokinase | Tarui's disease |
GSD type IX | phosphorylase kinase | - |
GSD type XI | glucose transporter | Fanconi-Bickel disease |
GSD type 0 | glycogen synthase | - |
