A novel variant of fructose-1,6-bisphosphatase gene identified in an adult with newly diagnosed hepatitis C.

Hepatic fructose-1,6-bisphosphatase (FBPase) deficiency commonly presents with acute crises during infancy when glycogen stores are depleted. In these patients, dependence on glycogenolysis means that the duration of normoglycaemia is related to liver glycogen stores. Clinical hallmarks of FBPase deficiency include hypoglycaemia and lactic acidosis with or without ketosis.
