The GATM gene codes for the enzyme guanidinoacetate N-methyltransferase, which is involved in the synthesis of creatine. Creatine is an important compound that plays a key role in energy metabolism, particularly in tissues that require rapid energy turnover such as the brain and muscles.

Changes or variants in the GATM gene can lead to guanidinoacetate methyltransferase deficiency, a rare genetic disorder characterized by the impaired production of creatine. This deficiency can result in intellectual disability, developmental delay, and muscle weakness.

The GATM gene is listed in various genetic databases, including OMIM, Genes & Diseases, PubMed, and GeneCards. These resources provide additional information on the genetic variant associated with guanidinoacetate methyltransferase deficiency, as well as clinical tests, scientific articles, and other references related to this gene.

For individuals affected by guanidinoacetate methyltransferase deficiency, genetic testing and clinical evaluation are essential for diagnosis and treatment. The Genetic Testing Registry can provide information on available tests, while the Online Mendelian Inheritance in Man (OMIM) database offers comprehensive information on the clinical features, genetics, and management of this condition.

The GATM gene, also known as the amidinotransferase gene, is involved in the production of guanidinoacetic acid (GAA), an amino acid involved in energy metabolism.

Genetic changes in the GATM gene can lead to various health conditions, including:

Preventable medical errors kill about 22,000 patients a year, according to research from the Yale School of Medicine. That’s much less than a previously reported number of 250,000 deaths a year where medical error is to blame.

  • Guanidinoacetate methyltransferase (GAMT) deficiency: This genetic condition is characterized by a deficiency of the enzyme guanidinoacetate methyltransferase, which is encoded by the GATM gene. GAMT deficiency disrupts the production of creatine, a substance important for energy metabolism in muscles and the brain. This condition can lead to intellectual disability, seizures, and developmental delays.
  • Arginineglycine amidinotransferase (AGAT) deficiency: AGAT deficiency is another genetic condition related to changes in the GATM gene. This condition affects the production of creatine, leading to intellectual disability, seizures, and muscle weakness.
  • Other genetic changes in the GATM gene: In addition to GAMT and AGAT deficiencies, genetic changes in the GATM gene may be associated with other health conditions that are yet to be fully understood.

Genetic testing can be done to identify changes in the GATM gene and diagnose these health conditions. Clinical geneticists and other healthcare professionals can provide further information and guidance regarding genetic testing and management of these conditions.

For additional information on health conditions related to GATM gene changes, you can refer to the following resources:

  1. Scientific articles listed on PubMed and other scientific databases, which provide in-depth research on these conditions and their genetic basis.
  2. The Online Mendelian Inheritance in Man (OMIM) database, which provides comprehensive information on genetic disorders and the genes associated with them.
  3. Registry databases and catalogs that collect and provide information on specific genetic diseases and associated genes.

It is important to consult with healthcare professionals and genetic specialists when seeking information and pursuing genetic testing for health conditions related to GATM gene changes.

Arginineglycine amidinotransferase deficiency

Arginineglycine amidinotransferase deficiency is a genetic disorder characterized by a deficiency of the arginineglycine amidinotransferase (GATM) enzyme. This enzyme plays a key role in the production of guanidinoacetic acid (GAA), which is an important precursor for creatine synthesis in the body. The GATM gene, which codes for this enzyme, is related to the energy metabolism and other amino acid-related processes.

Clinical manifestations of arginineglycine amidinotransferase deficiency can vary widely, but often include intellectual disability, muscle weakness, and delays in motor development. In some cases, affected individuals may also have distinctive facial features such as a prominent forehead, flat nasal bridge, and a pointed chin, which has led to the condition being referred to as “beard” syndrome.

Diagnosis of arginineglycine amidinotransferase deficiency typically involves genetic testing to identify changes in the GATM gene. This can be done through targeted testing of known variants or through more comprehensive testing methods such as whole exome sequencing. Additional testing may include measurement of creatine and GAA levels in urine and plasma.

Information on arginineglycine amidinotransferase deficiency can be found in scientific databases and resources such as OMIM, PubMed, and various genetic disease registries. These sources provide details on the clinical characteristics, genetic changes, and management options for the condition. Researchers and healthcare professionals often refer to these resources when studying or treating arginineglycine amidinotransferase deficiency.

References to articles and studies related to arginineglycine amidinotransferase deficiency can be found in scientific journals and databases. These references provide important information on the disease and its management. Some of the key databases and resources for finding such references include PubMed, OMIM, and the Genetic Testing Registry.

In summary, arginineglycine amidinotransferase deficiency is a genetic disorder caused by changes in the GATM gene. It is associated with a range of clinical manifestations including intellectual disability and muscle weakness. Genetic testing and measurement of GAA and creatine levels are commonly used diagnostic tests for this condition. Resources such as OMIM, PubMed, and genetic disease registries provide valuable information on the condition.
