Deficiency in hepatic glycogen synthase. Deficiency in hydroxy-methylglutarylCoA lyase. Deficiency in hypoxanthine-guanine-phosphoribosyltransferase grade

Glycogen storage diseases are the result of deficiency of enzymes that cause the alteration of glycogen metabolism. The liver forms (type I, III, IV and VI) are marked by hepatomegaly due to increased liver glycogen and hypoglycemia caused by inability to convert glycogen to glucose. Glycogen storage disease type 0 is a disease characterized by a deficiency in the glycogen synthase enzyme. Although glycogen synthase deficiency does not result in storage of extra glycogen in the liver, it is often classified as a glycogen storage disease because it is another defect of glycogen storage and can cause similar problems.

The first patient presented at the age of 8 months with recurrent hypoglycemic seizures. The second patient presented at 14 months with asymptomatic incidental hyperglycemia.

glycogen synthase deficiency is likely to be more common than is believed today. It should be sought in children who, before the first meal of the day, present with drowsiness, lack of attention, pallor, uncoordinated eye movements, disorientation or convulsions and who have hypoglycaemia and acetone in …

2015-06-11 · It is caused by a deficiency of the enzyme glycogen synthetase in the liver, due to mutations in the GYS2 gene. It is inherited in an autosomal recessive manner. Treatment involves a specific diet that includes frequent meals with high protein intake during the day, and uncooked starch in the evening.

Katsuya Tanabe, Zhonghao Liu, Satish Patel, Bradley W Doble, Lin Li, Corentin Cras-Méneur, Sara C Martinez, Cris M Welling, Morris F White, Ernesto Bernal-Mizrachi 2019-01-24 · Enzyme deficiency results in glycogen accumulation in tissues. In many cases, the defect has systemic consequences, but in some cases, the defect is limited to specific tissues. Most patients experience muscle symptoms, such as weakness and cramps, although certain GSDs manifest as specific syndromes, such as hypoglycemic seizures or cardiomegaly. Glycogen storage disease due to muscle and heart glycogen synthase deficiency is characterised by muscle and heart glycogen deficiency. It has been described in three siblings (two brothers and their younger sister).
