N-acetylglutamate synthase deficiency, also known as NAGS deficiency, is a rare genetic condition that affects the urea cycle, a process that helps the body get rid of ammonia. This condition is caused by mutations in the N-acetylglutamate synthase gene, which is responsible for producing an enzyme called N-acetylglutamate synthase.

N-acetylglutamate synthase is essential for the urea cycle, as it helps to produce N-acetylglutamate, a molecule that activates the first step of the cycle. Without this enzyme, ammonia builds up in the body, leading to a range of symptoms, including vomiting, seizures, and changes in brain function.

NAGS deficiency is inherited in an autosomal recessive manner, which means that an individual must inherit two copies of the mutated gene – one from each parent – in order to develop the condition. Parents who are carriers of the gene mutation do not typically have any symptoms of NAGS deficiency.

Diagnosis of NAGS deficiency can be done through genetic testing, which looks for mutations in the N-acetylglutamate synthase gene. Additional testing may be done to assess the function of the enzyme and measure ammonia levels in the blood.

Treatment for NAGS deficiency involves managing symptoms and preventing the build-up of ammonia in the body. This may include dietary changes, such as a low-protein diet, and the use of medications that help to remove excess ammonia. Regular monitoring and follow-up with healthcare professionals are important for managing the condition.

Research studies and clinical trials are ongoing to learn more about the genetic causes, clinical features, and treatment options for NAGS deficiency. Advocacy organizations and rare disease resources can provide support and additional information for patients and their families.

Pre-tax flexible spending accounts (FSAs) are often touted as the answer to high out-of-pocket medical costs, but many FSAs have “use it or lose it” rules. FSA holders lose $50 to $100 per year on average, CBS News reported, but since you’re allowed to contribute up to $2,650, you could risk losing thousands of dollars if you don’t spend your FSA money in time.

Frequency

N-acetylglutamate synthase deficiency (NAGS) is a rare genetic disorder that affects the urea cycle. It is estimated to occur in about 1 in every 2 million live births worldwide.

According to genetic testing conducted at the N-acetylglutamate Information Center, mutations in the NAGS gene have been found to be the cause of this condition in affected individuals. Data from PubMed research articles and the OMIM database support this information.

The frequency of NAGS deficiency varies among different populations. It is more common in certain ethnic groups, such as Ashkenazi Jews, where the frequency is estimated to be 1 in 75,000 births.

Additional information on the frequency of NAGS deficiency can be found through the N-acetylglutamate Information Center, which provides resources and advocacy support for patients and families affected by this condition. The center also offers genetic testing services and can provide more information on inheritance patterns and associated diseases.

Overall, N-acetylglutamate synthase deficiency is a rare genetic disorder with a low frequency in the general population. However, it may be more prevalent in specific ethnic groups. More research and information are needed to fully understand the causes and frequency of this condition.

Causes

N-acetylglutamate synthase deficiency (NAGS) is a rare genetic condition caused by mutations in the NAGS gene, which provides instructions for making the N-acetylglutamate synthase enzyme. This enzyme plays a critical role in the urea cycle, a series of chemical reactions that occur in the liver and are responsible for removing ammonia from the body.

Ammonia is a waste product that is produced when proteins are broken down in the body. Normally, the urea cycle converts ammonia into urea, which can be safely excreted in urine. However, in individuals with NAGS deficiency, the enzyme needed for this conversion is not produced in sufficient amounts or does not function properly. As a result, ammonia builds up in the blood, leading to high levels of ammonia in the body, a condition known as hyperammonemia.

NAGS deficiency is inherited in an autosomal recessive pattern, which means that an affected individual must inherit two copies of the mutated gene, one from each parent. Individuals who inherit only one copy of the mutated gene are known as carriers and typically do not show any symptoms of the condition.

The NAGS gene is located on chromosome 17, and more than 50 different mutations in this gene have been associated with NAGS deficiency. These mutations can vary widely in their effects on enzyme function, which may contribute to the variability in symptoms and severity seen in individuals with this condition.

Diagnosing NAGS deficiency typically involves a combination of clinical symptoms, laboratory testing, and genetic testing. Blood tests can measure ammonia levels and other markers of urea cycle function, while genetic testing can identify mutations in the NAGS gene. Additional testing, such as imaging studies of the brain, may be done to evaluate the extent of damage caused by hyperammonemia.

More information about the genetics of NAGS deficiency, including a list of specific mutations and their associated effects, can be found in the OMIM database. OMIM is a comprehensive catalog of human genes and genetic disorders, and it provides a valuable resource for researchers, clinicians, and patients seeking information on genetic conditions.

Catalog of Genes and Diseases from OMIM

N-acetylglutamate synthase deficiency (NAGS deficiency) is a rare genetic condition caused by mutations in the gene called NAGS. N-acetylglutamate synthase is an enzyme involved in the urea cycle, which plays a crucial role in the removal of ammonia from the body.

Patients with NAGS deficiency have a reduced ability to produce N-acetylglutamate, a molecule necessary for the proper functioning of the urea cycle. As a result, ammonia accumulates in the blood and can cause serious neurological symptoms, such as seizures, lethargy, and developmental delay.

NAGS deficiency is inherited in an autosomal recessive manner, meaning that an individual must inherit two copies of the mutated NAGS gene to develop the condition. It is a rare condition, with an estimated frequency of less than 1 in 1,000,000 births.

Diagnosis of NAGS deficiency can be confirmed through genetic testing, which identifies mutations in the NAGS gene. This testing can be ordered by a healthcare provider familiar with the condition.

Research has shown that early diagnosis and treatment can significantly improve outcomes for patients with NAGS deficiency. Treatment typically involves a low-protein diet and supplementation with N-carbamylglutamate, a medication that helps to activate the urea cycle. Regular monitoring of ammonia levels in the blood is also important for managing the condition.

There are ongoing research studies and clinical trials investigating potential new treatments for NAGS deficiency. For more information on these studies, visit the clinicaltrials.gov website and search “N-acetylglutamate synthase deficiency.”

For additional resources and support, organizations such as the N-acetylglutamate Deficiency Advocacy Group and the Cycle for NAGS Research Center provide information, advocacy, and support to patients and families affected by NAGS deficiency.
