Glycogen storage diseases are caused by the lack of an enzyme needed to change glucose into glycogen and break down glycogen into glucose. Type VII (Tarui disease) is most commonly seen in Ashkenazi Jews and the Japanese. Hypoglycemia, hyperlipidemia and growth retardation are commonly observed, but some symptoms are specific for certain subtypes, such as elevated blood lactate (type I), profound neutropenia (type Ib), ketosis (types VI and 0) and cardiomyopathy (type II). Questions sent to GARD may be posted here if the information could be helpful to others. Glycogen is synthesized when excess concentrations of glucose are introduced through food, but the body can store limited amounts of glycogen. Patients with the classic infantile form of Pompe disease are the most severely affected. There are four symptoms that might cause the doctor to suspect a type of GSD that affects the liver. In general, the prognosis of GSDs range from mild to severe and rapidly fatal across different subtypes , but early recognition of the disease may prevent complications such as hepatic, respiratory and cardiac failure, which will invariably prolong the patient's life. If your child's doctor suspects a glycogen storage diseases, he or she will ask about your child's symptoms … All of these enzymes are deficient in certain types of GSDs, with the common end-result being inability of the liver and muscles to degrade glycogen and provide the necessary energy for metabolic functions, which manifests in a variety of symptoms, depending on the subtype and the severity of enzyme deficiency.

It is unclear how tubular aggregates are associated with the signs and symptoms … There are numerous forms of glycogen storage diseases, but the common end-result is inability to store glycogen in either the liver and/or muscles due to enzyme deficiencies that are transmitted by an autosomal recessive pattern of inheritance. Symptoms of low blood glucose, or hypoglycemia, include sweating, tremor, drowsiness, confusion, and, sometimes, seizures. Making the diagnosis may be quite difficult, but liver or skeletal muscle symptoms together with hypoglycemia that do not have an identifiable cause should rise suspicion toward GSDs.

GSDs roughly develop in approximately 1 per 25,000 individuals and gender distribution is mostly equal. Glycogen storage disease type I (also known as GSDI or von Gierke disease) is an inherited disorder caused by the buildup of a complex sugar called glycogen in the body's cells. In some cases, diet therapy is helpful. Treatment principles almost strictly depend on the type of GSD: Management of hypoglycemia through dietary changes and additional symptoms is imperative for other GSDs, but in general, this approach is favored across all subtypes so that the metabolic needs for glycogen and energy are fulfilled. Enzyme deficiency that impairs normal glycogen degradation is the principal cause of all GSDs (except in type 0, where glycogen synthase deficiency results in impaired glycogen storage in the liver) . Enzyme deficiencies occur as a result of genetic mutations that are transferred from parent to their child through an autosomal recessive pattern of inheritance.
