Glycogen storage diseases and the liver.
Carbohydrate metabolism in the liver is responsible for plasma glucose homeostasis. Liver glycogen storage diseases are metabolic disorders which result in abnormal storage amounts and/or forms of glycogen, and often (but not always) have hepatomegaly and hypoglycaemia as presenting features. To understand the clinical complexity of the glycogen storage diseases, it is necessary to understand the properties and regulation of the proteins involved in glycogen metabolism. Advances in treatment have greatly improved metabolic control and hence the quality of life and survival. However, the lack of understanding of the molecular basis of some of the clinical features of glycogen storage diseases makes it difficult logically to devise optimal treatment regimens to prevent some of the long-term complications. Recently, molecular biology has greatly advanced our understanding of the proteins and genes involved in liver glycogen metabolism and has led to better and less invasive methods of diagnosis of these disorders.
