Glycogen storage disease type I (GSDI), also known as glycogen storage disease type Ia (GSDIa) or von Gierke disease, is a rare genetic disorder characterized by the inability of the body to break down glycogen into glucose. This results in the accumulation of glycogen in various tissues and organs, particularly the liver and kidneys. GSDI is caused by mutations in the G6PC gene, which codes for the enzyme glucose-6-phosphatase.

There are two types of GSDI: GSDIa and GSDIb. GSDIa is the more common type and is associated with hepatorenal dysfunction, severe hypoglycemia, and growth retardation. GSDIb is a milder form of the disease that is characterized by neutropenia and an increased susceptibility to bacterial infections.

The frequency of GSDI is estimated to be 1 in 100,000 to 1 in 200,000 births, making it a rare condition. It is inherited in an autosomal recessive manner, meaning that both parents must carry a copy of the mutated gene for the disease to occur in their child.

Diagnosis of GSDI can be confirmed through genetic testing, which looks for mutations in the G6PC gene. Additional testing may include liver biopsies and blood tests to evaluate glucose and glycogen levels. Treatment for GSDI involves a strict diet that limits intake of carbohydrates and regular monitoring of blood glucose levels.

There is currently no cure for GSDI, and management of the disease focuses on preventing complications and managing symptoms. Research studies and clinical trials are ongoing to learn more about the underlying causes of GSDI and explore potential treatments. Support resources for patients and families affected by GSDI can be found through organizations such as the American Glycogen Storage Disease Association and the Genetic and Rare Diseases Information Center.

For more information about Glycogen storage disease type I, refer to articles available on OMIM, PubMed, and other scientific research databases. Additionally, clinical trials related to GSDI can be found on ClinicalTrials.gov, and the Genetic Testing Registry provides information on genetic testing options for this condition.

Frequency

Glycogen storage disease type I (GSDI) is a rare genetic disorder caused by a defect in the gene that codes for glucose-6-phosphatase (G6PC) enzyme. This enzyme is involved in the breakdown and release of stored glucose (in the form of glycogen) into the bloodstream. As a result of this defect, glycogen cannot be properly stored and released by the body’s tissues, leading to problems with glucose homeostasis.

GSDI is inherited in an autosomal recessive manner, meaning that an affected individual must inherit two copies of the defective gene, one from each parent. The frequency of GSDI varies among different populations, with GSDIa being the most common subtype. The estimated frequency of GSDIa is approximately 1 in 100,000 to 1 in 200,000 live births in the general population.

There are several types of GSDI, including GSDIa, GSDIb, and GSDIc. GSDIa is the most common type and is characterized by the deficiency of the glucose-6-phosphatase enzyme in the liver, kidneys, and intestines. GSDIb is associated with additional neutropenia (low levels of neutrophils in the blood) and is caused by a defect in the glucose-6-phosphate transporter protein. GSDIc is a rare type that is caused by a defect in the glucose-6-phosphate translocase protein.

Studies on the frequency and distribution of GSDI have been conducted in various populations. For example, a study published in the American Journal of Medical Genetics reported a frequency of GSDIa in the American population to be approximately 1 in 400,000 live births. Another study published in the Journal of Medical Genetics estimated the frequency of GSDIa in the Ashkenazi Jewish population to be 1 in 20,000 live births.

More information about the frequency of GSDI can be found in resources such as the Online Mendelian Inheritance in Man (OMIM) database, which provides comprehensive information on genetic diseases and associated genes. The Genetics Home Reference website also provides information on the frequency of genetic diseases and resources for genetic testing, research, and advocacy.

Causes

Glycogen storage disease type I (GSDI) is a rare genetic condition caused by mutations in the G6PC or SLC37A4 genes. These genes provide instructions for making proteins involved in the breakdown and production of glycogen, which is a form of stored glucose in the body. Mutations in these genes disrupt the normal function of glucose-6-phosphatase, an enzyme that converts stored glycogen into glucose for energy.

GSDI is inherited in an autosomal recessive pattern, which means that both copies of the gene in each cell have mutations. Parents of an individual with GSDI usually carry one copy of the mutated gene but do not show signs of the condition.

There are two types of GSDI: type Ia (GSDIa) and type Ib (GSDIb). GSDIa is caused by mutations in the G6PC gene, while GSDIb is caused by mutations in the SLC37A4 gene. GSDIa is the most common type and is associated with symptoms such as hepatorenal (liver and kidney) problems and neutropenia (low white blood cell count). GSDIb, in addition to the symptoms of GSDIa, is also associated with inflammatory bowel disease.

Research studies have identified more than 100 mutations in the G6PC gene and several mutations in the SLC37A4 gene that cause GSDI. The frequency of these mutations varies among different populations.

To learn more about the specific mutations associated with GSDI, you can refer to databases such as OMIM (Online Mendelian Inheritance in Man), PubMed, and the GSDI Center for information

Additional scientific articles, genetic testing resources, and advocacy groups may provide more information on the causes and inheritance of GSDI. ClinicalTrials.gov is also a valuable resource to find ongoing research studies and clinical trials related to GSDI.

Learn more about the genes associated with Glycogen storage disease type I

Glycogen storage disease type I (GSDI) is a rare genetic disorder that affects the body’s ability to break down glycogen, a stored form of glucose in the body. There are two types of GSDI – GSDIa, which is caused by a deficiency of the enzyme glucose-6-phosphatase, and GSDIb, which is caused by a deficiency of the enzyme glucose-6-phosphate translocase.

See also  ITGB2 gene

The genes associated with GSDI are G6PC and SLC37A4. Mutations in the G6PC gene cause GSDIa, while mutations in the SLC37A4 gene cause GSDIb. These genes provide instructions for making proteins that are involved in the breakdown of glycogen in the liver and kidneys.

Frequency: GSDIa is estimated to occur in about 1 in 100,000 to 200,000 births worldwide, while GSDIb is even rarer with an estimated frequency of 1 in 1 million to 10 million births.

Causes: In GSDIa, mutations in the G6PC gene result in a deficiency of the glucose-6-phosphatase enzyme. This leads to an accumulation of glycogen in the liver and kidneys, causing the characteristic symptoms of GSDI. In GSDIb, mutations in the SLC37A4 gene lead to a deficiency of the glucose-6-phosphate translocase enzyme, which affects the transport of glucose-6-phosphate out of the cell.

Inheritance: GSDI is inherited in an autosomal recessive manner, which means that an individual must inherit two copies of the mutated gene – one from each parent – to have the condition. If both parents are carriers of a GSDI mutation, each child has a 25% chance of inheriting the condition.

To learn more about the genes associated with GSDI and the conditions they cause, you can refer to genetic databases such as the Online Mendelian Inheritance in Man (OMIM) or the Human Gene Mutation Database (HGMD). These resources provide detailed information about the genes, their mutations, and the clinical manifestations of GSDI.

In addition, there are several advocacy and support organizations that provide resources for patients and families affected by GSDI, such as the American Liver Foundation and the Association for Glycogen Storage Disease. These organizations offer information about the disease, support services, and opportunities for participation in research studies and clinical trials.

Further research on the genetics of GSDI is ongoing, with scientific studies aimed at understanding the underlying molecular mechanisms of the disease and developing potential treatments. ClinicalTrials.gov is a valuable resource for finding information about ongoing research studies and clinical trials related to GSDI.

In conclusion, understanding the genes associated with GSDI is critical for diagnosis, genetic testing, and research purposes. By learning more about these genes and the genetic basis of the disease, we can advance our knowledge and develop better treatments for individuals with GSDI.

Inheritance

The inheritance of Glycogen Storage Disease Type I (GSDI) is autosomal recessive, which means that both parents must carry a copy of the defective gene for a child to be affected.

GSDI is caused by defects in the G6PC gene, which provides instructions for making the enzyme glucose-6-phosphatase. This enzyme is responsible for breaking down glycogen into glucose in the cells of the body.

There are two types of GSDI, GSDIA and GSDIB, which are associated with different mutations in the G6PC gene. GSDIA is the more common type and is usually found in the liver and kidneys, causing hepatorenal disease. GSDIB, on the other hand, can affect multiple tissues in the body and is associated with neutropenia (a decrease in the number of neutrophils, a type of white blood cell).

Since GSDI is a rare condition, there is limited information available about the frequency of the disease and the genes involved. However, there are resources and advocacy groups, such as the Glycogen Storage Disease Advocacy Association (GSDDA) and the American Genetic Association, that provide support and additional information about the condition.

The inheritance pattern and genetic cause of GSDI make genetic testing an important tool for diagnosis. Testing can also provide useful information for patients and their families, as well as for genetic research and clinical trials. ClinicalTrial.gov and OMIM (Online Mendelian Inheritance in Man) are valuable resources for finding studies and articles related to GSDI and other genetic diseases.

In conclusion, GSDI is a rare genetic condition inherited in an autosomal recessive manner. Defects in the G6PC gene cause problems in glycogen storage and glucose metabolism in the body. Additional information and resources about GSDI and its inheritance can be found through genetics centers, advocacy groups, and genetic research databases like ClinicalTrial.gov and OMIM.

Genetic Testing Information

Glycogen storage disease type I (GSDI) is a rare genetic condition caused by defects in genes associated with glucose-6-phosphatase, an enzyme involved in glycogen metabolism. There are two types of GSDI, namely GSDIa and GSDIb, each caused by mutations in different genes.

Genetic testing is available to diagnose GSDI and determine the specific gene defect causing the condition. The most common gene mutations associated with GSDIa are found in the G6PC gene, while mutations in the SLC37A4 gene are responsible for GSDIb. These tests can be performed on a blood or tissue sample, usually through a comprehensive panel test known as glycogen storage disease panel 1 (GSDP1).

The frequency of GSDI varies among different populations, with GSDIa being more common than GSDIb. Studies have shown that GSDIa affects approximately 1 in 100,000 to 200,000 people, while GSDIb is much rarer with an estimated incidence of 1 in 1 million to 10 million individuals.

Genetic testing not only provides a definitive diagnosis for GSDI but also allows for carrier testing and prenatal testing for families at risk. Carrier testing can identify individuals who carry a single copy of the mutated gene but do not show symptoms of the disease. Prenatal testing can be performed during pregnancy to determine if the fetus has inherited the gene defect causing GSDI.

In addition to GSDI, genetic testing can also be used to diagnose and determine the genetic cause of other rare diseases with associated glycogen storage problems, such as glycogen storage disease type II (Pompe disease) and glycogen storage disease type III (Cori disease).

Genetic testing for GSDI can be ordered by healthcare providers and is typically performed by specialized genetic testing laboratories. These laboratories often offer a range of genetic tests for various rare diseases and have resources available for patient support and advocacy.

More information about genetic testing for GSDI and other rare genetic diseases can be found on the websites of organizations like the Genetic and Rare Diseases Information Center (GARD) and the American College of Medical Genetics and Genomics.

Scientific articles and research studies on GSDI and its genetics can be found in databases like PubMed, OMIM, and clinicaltrialsgov. These resources provide valuable information for healthcare professionals and researchers interested in studying and treating GSDI.

Genetic and Rare Diseases Information Center

The Genetic and Rare Diseases Information Center (GARD) is an American resource that provides information on genetic and rare diseases. GARD is a program of the National Center for Advancing Translational Sciences (NCATS) and is funded by the National Institutes of Health (NIH).

GARD provides information about the causes, symptoms, diagnosis, and treatment of various genetic and rare diseases, including Glycogen Storage Disease Type I (GSDI). GSDI is a rare genetic disorder caused by a defect in the G6PC or G6PT gene, which affects the body’s ability to break down and store glucose-6-phosphatase (G6P).

There are several types of GSDI, with GSDIa being the most common. In GSDIa, the enzyme deficiency primarily affects the liver, causing hepatomegaly (enlarged liver) and hepatorenal (liver and kidney) symptoms. Other types of GSDI may affect different tissues within the body and have varying symptoms.

The frequency of GSDI varies among different populations. It is inherited in an autosomal recessive manner, meaning that both copies of the gene must be affected for an individual to have the condition. Individuals who only have one copy of the gene mutation are carriers and do not usually have symptoms of the disease.

Diagnosis of GSDI is typically confirmed through genetic testing, which can identify mutations in the G6PC or G6PT genes. Additional testing may be done to assess liver and kidney function, as well as to evaluate glucose and lactate levels.

There is currently no cure for GSDI, but treatment aims to manage symptoms and prevent complications. This may involve dietary modifications, such as frequent meals, a high complex carbohydrate and low simple sugar diet, and cornstarch supplementation. Regular monitoring of glucose levels and liver function is also important.

Patients and families affected by GSDI can find support and more information through various resources, including patient advocacy organizations, research studies, and clinicaltrials.gov, which provides information on ongoing clinical trials and research studies related to GSDI.
