Arginase deficiency is a rare genetic condition caused by mutations in the ARG1 gene. It is inherited in an autosomal recessive manner. Arginase is an enzyme that helps in the breakdown of arginine, an amino acid. The deficiency of this enzyme leads to the accumulation of arginine in the body, which can cause various health problems.

Clinical features of arginase deficiency include progressive developmental delay, intellectual disability, growth retardation, seizures, spasticity, and movement disorders. The severity and presentation of symptoms can vary widely from patient to patient.

Research studies, clinical trials, and genetic testing are ongoing to learn more about the causes, inheritance patterns, and associated conditions of arginase deficiency. The Genereviews.org website provides additional information on this rare condition and lists the names of research centers and advocacy organizations that offer support and resources for affected individuals and their families.

OMIM (Online Mendelian Inheritance in Man) and PubMed are scientific databases where you can find articles and references related to arginase deficiency. The Arg1 Deficiency Association and other advocacy organizations also provide support, information, and resources for individuals and families affected by this condition.

Frequency

Arginase deficiency is a rare genetic condition. It is estimated that this condition affects less than 1 in 1 million individuals worldwide.

Arginase deficiency is an autosomal recessive condition, which means that both copies of the ARG1 gene in each cell have mutations. This condition occurs equally in males and females.

Nearly 60% of Americans surveyed support a Medicare for All program, according to Business Insider. Those in favor of Medicare for All include 75% of Democrats, 58% of registered Independents and 36% of Republicans, though Republican support jumps up to 64% when discussing an optional expanded Medicare program, also referred to as “Medicare for Some.”

The condition has been reported in various populations around the world, including the United States, Europe, and Japan.

According to the OMIM database, there are currently 65 diseases associated with Arginase deficiency, including developmental delay, intellectual disability, seizures, spasticity, and liver disease.

References to the genes associated with Arginase deficiency can be found in the Genereviews database and clinical trials can be found on ClinicalTrials.gov.

• Smith DE, et al. Arginase deficiency: insights into rare diseases and urea cycle disorders. Yale J Biol Med. 2019;92(3):481-489.

Causes

Arginase deficiency is caused by mutations in the ARG1 gene. This gene is responsible for producing the arginase enzyme, which plays a crucial role in the urea cycle. Mutations in the ARG1 gene disrupt the normal functioning of the arginase enzyme, leading to a deficiency. The inheritance of arginase deficiency is autosomal recessive, which means that an affected individual inherits two copies of the mutated gene, one from each parent.

Arginase deficiency is a rare genetic condition, and the exact frequency is not well known. It is estimated to affect fewer than 1 in 1 million people worldwide.

Inheritance

Arginase deficiency is a rare genetic condition caused by mutations in the ARG1 gene. It is inherited in an autosomal recessive manner, which means that both copies of the gene must be mutated for the condition to occur.

Parents of an individual with arginase deficiency each carry one copy of the mutated gene, but do not typically show any signs or symptoms of the condition. When both parents pass their mutated copy of the gene to their child, the child will have arginase deficiency.

The frequency of arginase deficiency is unknown, but it is thought to be a rare disease. It has been reported in individuals from various ethnic backgrounds.

Genetic testing can be used to confirm a diagnosis of arginase deficiency. Testing can also be helpful for identifying carriers in families and for providing genetic counseling.
