" /> Glycogen storage disease due to liver glycogen synthase deficiency - CISMeF





Preferred Label : Glycogen storage disease due to liver glycogen synthase deficiency;

ICD-11 definition : Hepatic glycogen synthase deficiency, or glycogen storage disease (GSD) type 0, is a genetically inherited anomaly of glycogen metabolism and a form of GSD characterized by fasting hypoglycemia. This is not a glycogenosis, strictly speaking, as the enzyme deficiency decreases glycogen reserves. Patients present with morning fatigue and fasting hypoglycemia (without hepatomegaly) associated with hyperketonemia but without hyperalaninemia or hyperlactacidemia. After meals, major hyperglycemia associated with lactate and alanine increase and hyperlipidemia is observed.;

ICD-11 synonym : Glycogen storage disease type 0A; GSD type 0A; Glycogenosis type 0A;
