Glycogen storage disease type 0 is a disease characterized by a deficiency in the glycogen synthase enzyme (GSY). 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.

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.

2023年6月26日 · There are at least 19 different types of glycogen storage disease based on which enzyme is affected. How common is glycogen storage disease? Glycogen storage disease is rare. GSD type I (von Gierke disease), the most common type, occurs in approximately 1 in 100,000 births. What are the symptoms of glycogen storage disease?

2025年1月21日 · In GSD type 0, a liver biopsy typically shows decreased hepatic glycogen and can make a definitive diagnosis for this disease. [15] In GSD type I, a liver biopsy should reveal pale-staining, swollen hepatocytes, steatosis, and nuclear hyper-glycogenation.

Type 0 glycogen storage disease (GSD0) is caused by deficiency of the hepatic isoform of glycogen synthase. [1] Although GSD0 has been classified as a glycogen storage disease (GSD), this is a misnomer.

Type 0 Glycogen Storage Disease (GSD 0) is caused by a deficiency in the enzyme named glycogen synthase. This enzyme is needed for the body to make glycogen. When a person has glycogen synthase deficiency the amount of glycogen …

Glycogen storage disease (GSD) type 0, VI and IX are inborn errors of metabolism involving hepatic glycogen synthesis and degradation. We performed a characterization of a large Italian cohort of 30 patients with GSD type 0a, VI, IXa, IXb and IXc.

2020年8月11日 · Glycogen storage disease type 0 (GSD0) is an autosomal recessive disorder caused by a sequence variant in the GYS2 gene, leading to decreased or absent activity of hepatic glycogen synthase. With a frequency of less than 1 in 1,000,000 individuals, GSD0 represents only around 1% of all glycogen storage disease cases but it might be underrecognized.

Inborn error of metabolism of glucose caused by decreased glycogen synthetase activity and characterized by fasting hypoglycemia, high blood ketones, increased free fatty acids, and low levels of alanine and lactate beginning in early infancy. Conversely, feeding results in hyperglycemia and hyperlactatemia.

There are two types of Glycogen Storage Disease 0; Muscle GSD 0 and Liver GSD 0. Muscle GSD 0 is where glycogen formation in the muscles is impaired and Liver GSD 0 is where glycogen formation in the liver is impaired. Glycogen Storage Disease 0 is inherited via an autosomal recessive inheritance pattern, please see diagram below.
