(2010) Glycogenin-1 deficiency and inactivated priming of glycogen synthesis. N Engl J Med. 362:1203-10. Tajsharghi H, Leren TP, Abdul-Hussein S, Tulinius M, 

The two index cases presented with morning fatigue, had ketotic hypoglycaemia when fasting which rapidly disappeared after eating, and hepatic glycogen deficiency and absent or very low hepatic glycogen synthase activity. We report two new cases of liver glycogen synthase deficiency (GSD0). 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.

Mutations in The glycogen storage diseases comprise several inherited diseases caused by abnormalities of enzymes that regulate the synthesis or degradation of glycogen. In contrast to the classic hepatic glycogen storage diseases that are characterized by fasting hypoglycemia and hepatomegaly, the liver is not enlarged in GSD0. [Glycogen synthase deficiency].

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.

A deficiency of the liver enzyme may lead to a type of hypoglycemia.

In these situations, the debranching enzyme is necessary, which will straighten out the chain in that area. In addition, the enzyme transferase shifts a block of 3 glucosyl residues 2001-08-01 Glycogen is formed in periods of dietary carbohydrate loading and broken down when glucose demand is high or dietary availability is low (figure 1). There are a number of inborn errors of glycogen metabolism that result from mutations in genes for virtually all of the proteins involved in glycogen synthesis, degradation, or regulation. Background: Glycogen synthase deficiency (glycogen storage disease 0 - GSD 0) caused by mutations in the GYS2 gene is characterized by a lack of glycogen synthesis in the liver.

Glycogen storage disease type 0 (also known as GSD 0) is a condition caused by the body's inability to form a complex sugar called glycogen, which is a major source of stored energy in the body. GSD 0 has two types: in muscle GSD 0, glycogen formation in the muscles is impaired, and in liver GSD 0, glycogen formation in the liver is impaired.

Glycogen synthesis is initiated by self-glucosylation of the glycosyltransferases Glycogenin-1 Deficiency and Inactivated Priming of Glycogen Synthesis.

Mutations in the GYS1 or GYS2 gene lead to a lack of functional glycogen synthase, which prevents the production of glycogen from glucose. Mutations that cause GSD 0 result in a complete absence of glycogen in either liver or muscle cells. This enzyme is needed for the body to make glycogen. When a person has glycogen synthase deficiency the amount of glycogen that the body can store in the liver is very low. Low amounts of glycogen in the liver mean that when a person is not eating (fasting) their blood sugar levels can get very low (hypoglycemia). Autosomal recessive deficiency of hepatic glycogen synthase. Inability to store hepatic glycogen results in postprandial hyperglycemia, hyperlactatemia, and hyperlipidemia alternating with fasting ketotic hypoglycemia associated with low alanine and lactate concentrations.
