What is the treatment for Type 1 glycogen storage disease?
The treatment of type I glycogen storage disease is focused on correcting the metabolic changes in the body and promoting the growth and development of the child. A combination of uncooked cornstarch mixed in water, soy formula, or soy milk is often recommended.
What gene causes glycogen storage disease?
Mutations in the G6PC gene result in a deficiency in the glucose-6-phosphatase (G6Pase) enzyme and account for approximately 80% of GSDI. This type of GSDI is termed glycogen storage disease type Ia.
What are the treatment management for the different glycogen storage diseases?
In general, no specific treatment exists to cure glycogen storage diseases (GSDs). In most cases, the mainstay of management involves measures to reduce hypoglycemia, including frequent meals and consumption of uncooked cornstarch.
What diseases are treated with gene therapy?
Gene therapy holds promise for treating a wide range of diseases, such as cancer, cystic fibrosis, heart disease, diabetes, hemophilia and AIDS. Researchers are still studying how and when to use gene therapy. Currently, in the United States, gene therapy is available only as part of a clinical trial.
What causes glycogen storage disease type 1?
Glycogen storage disease type 1A is caused by the deficiency of glucose-6-phosphatase (G6Pase) catalytic activity which results from mutations in the G6PC gene . This condition is inherited in an autosomal recessive pattern.
How is von Gierke disease treated?
The goal of treatment is to avoid low blood sugar. Eat frequently during the day, especially foods that contain carbohydrates (starches). Older children and adults may take cornstarch by mouth to increase their carbohydrate intake.
What are the types of glycogen storage diseases?
Types of GSD
- Type I or von Gierke disease. This is the most common form of GSD.
- Type III, Cori disease, or Forbes disease. People with type III don’t have enough of an enzyme called the debranching enzyme, which helps break down glycogen.
- Type IV or Andersen disease. People with type IV form abnormal glycogen.
How many types of glycogen storage disease are there?
There are at least 13 types of glycogen storage disease. Doctors know more about some types than others. GSD mostly affects the liver and the muscles.
What are two different types of glycogen storage disease?
Types of Glycogen Storage Disease
- Type I (Von Gierke disease) – this is the most common type of glycogen storage disease, and accounts for 90% of all glycogen storage disease cases.
- Type II (Pompe’s disease, acid maltase deficiency)
- Type III (Cori’s disease)
- Type IV (Andersen’s disease)
- Type V (McArdle’s disease)
What are examples of gene therapy?
Gene therapy is the introduction of genes into existing cells to prevent or cure a wide range of diseases. For example, suppose a brain tumor is forming by rapidly dividing cancer cells. The reason this tumor is forming is due to some defective or mutated gene.
Is glycogen storage disease a genetic disorder?
Glycogen storage disease is passed down from parents to children (hereditary). It happens because both parents have an abnormal gene (gene mutation) that affects a specific way that glycogen is stored or used. Most GSDs occur because both parents pass on the same abnormal gene to their children.
