Asparagine synthetase deficiency

Asparagine synthetase deficiency is a rare genetic condition that affects the production of the enzyme asparagine synthetase. This enzyme is essential for the synthesis of the amino acid asparagine, which is important for normal brain function. Without enough asparagine synthetase, individuals with this condition may experience developmental delay, intellectual disability, and other neurological problems.

This condition is caused by mutations in the ASNS gene, which encodes the asparagine synthetase enzyme. These mutations can lead to a complete absence of the enzyme or a reduced activity, resulting in a deficiency of asparagine. Asparagine synthetase deficiency is inherited in an autosomal recessive manner, meaning that both copies of the ASNS gene must be mutated for the condition to occur.

Diagnosis of asparagine synthetase deficiency can be made through genetic testing, which can identify mutations in the ASNS gene. Additionally, clinical trials and research studies are underway to learn more about the condition and develop potential treatments. ClinicalTrials.gov is a valuable resource for finding information about ongoing clinical trials and research studies related to asparagine synthetase deficiency.

For individuals and families affected by asparagine synthetase deficiency, there are also advocacy and support resources available. Organizations such as the Genetic and Rare Diseases Information Center (GARD) and the National Organization for Rare Disorders (NORD) provide scientific information, support, and additional resources for individuals with rare genetic conditions.

To learn more about asparagine synthetase deficiency, you can also refer to articles and references available on PubMed and OMIM. These resources provide up-to-date scientific information and research studies on the condition. It is important to consult with healthcare professionals and genetic counselors for proper diagnosis, testing, and management of asparagine synthetase deficiency.

Inheritance

Asparagine synthetase deficiency is an inherited condition caused by mutations in the ASNS gene. The ASNS gene provides instructions for making the enzyme asparagine synthetase, which is involved in the production of the amino acid asparagine. Mutations in this gene result in a shortage or absence of functional asparagine synthetase, leading to the signs and symptoms of this condition.

This condition is inherited in an autosomal recessive pattern, which means that both copies of the ASNS gene in each cell have mutations. The parents of an individual with asparagine synthetase deficiency each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.

Genetic testing can confirm a diagnosis of asparagine synthetase deficiency by identifying mutations in the ASNS gene. This testing may also be used to determine whether other family members are carriers of the condition.

More information about the inheritance and genetics of asparagine synthetase deficiency can be found in the “Inheritance” section of the ASNS gene entry in the Online Mendelian Inheritance in Man (OMIM) catalog (OMIM entry 615574).
