hepatic glycogenosis

Definition: Glycogenoses are a number of genetic syndromes have been identified that result from some metabolic defect in the synthesis or catabolism of glycogen. The best understood and most important glycogenoses includes the glycogen storage diseases (GSDs), resulting from a hereditary deficiency of one of the enzymes involved in the synthesis or sequential degradation of glycogen.

Depending on the tissue or organ distribution of the specific enzyme in the normal state, glycogen storage in these dis-orders may be limited to a few tissues, may be more wide-spread while not affecting all tissues, or may be systemic in distribution.

Classification

- glycogen storage disease type I (GSD1)
- glycogen storage disease type II (GSD2)
- glycogen storage disease type III (GSD3)
- glycogen storage disease type IV (GSD4)
- glycogen storage disease type V (GSD5)
- glycogen storage disease type VI (GSD6)
- glycogen storage disease type VII (GSD7)
