Argininosuccinic aciduria is an inherited disorder that causes ammonia to accumulate in the blood. Ammonia, which is formed when proteins are broken down in the body, is toxic if the levels become too high. The nervous system is especially sensitive to the effects of excess ammonia. Argininosuccinic aciduria usually becomes evident in the first few days of life. An infant with argininosuccinic aciduria may be lacking in energy (lethargic) or unwilling to eat, and have poorly controlled breathing rate or body temperature. Some babies with this disorder experience seizures or unusual body movements, or go into a coma. Complications from argininosuccinic aciduria may include developmental delay , intellectual disability , progressive liver damage, skin lesions, and brittle hair. The condition is caused by mutations in the ASL gene and is inherited in an autosomal recessive pattern. Long-term management includes dietary restriction of protein and supplementation with arginine. Acute crises may be treated by discontinuing oral protein intake, supplementing oral intake with intravenous lipids and/or glucose, and use of intravenous arginine and nitrogen scavenging therapy. If ammonia levels do not normalize, hemodialysis may be necessary.
MalaCards based summary : Argininosuccinic Aciduria, also known as argininosuccinate lyase deficiency, is related to carbamoyl phosphate synthetase i deficiency, hyperammonemia due to and phenylketonuria, and has symptoms including seizures, vomiting and ataxia. An important gene associated with Argininosuccinic Aciduria is ASL (Argininosuccinate Lyase), and among its related pathways/superpathways are Arginine biosynthesis and Alanine, aspartate and glutamate metabolism. The drugs Nitric Oxide and Phenylacetic acid have been mentioned in the context of this disorder. Affiliated tissues include liver, skin and brain, and related phenotypes are aminoaciduria and oroticaciduria Disease Ontology : 12 An amino acid metabolic disorder that involves the accumulation of argininosuccinic acid (ASA) in the blood and urine. Genetics Home Reference : 25 Argininosuccinic aciduria is an inherited disorder that causes ammonia to accumulate in the blood. Ammonia, which is formed when proteins are broken down in the body, is toxic if the levels become too high. The nervous system is especially sensitive to the effects of excess ammonia. Argininosuccinic aciduria usually becomes evident in the first few days of life. An infant with argininosuccinic aciduria may be lacking in energy (lethargic) or unwilling to eat, and have a poorly controlled breathing rate or body temperature. Some babies with this disorder experience seizures or unusual body movements, or go into a coma. Complications from argininosuccinic aciduria may include developmental delay and intellectual disability. Progressive liver damage, high blood pressure (hypertension), skin lesions, and brittle hair may also be seen. Occasionally, individuals may inherit a mild form of the disorder. These individuals can have an accumulation of ammonia in the bloodstream only during periods of illness or other stress, or mild intellectual disability or learning disabilities with no evidence of elevated ammonia levels. OMIM : 56 Argininosuccinic aciduria is an autosomal recessive disorder of the urea cycle. Urea cycle disorders are characterized by the triad of hyperammonemia, encephalopathy, and respiratory alkalosis. Five disorders involving different defects in the biosynthesis of the enzymes of the urea cycle have been described: ornithine transcarbamylase deficiency (311250), carbamyl phosphate synthetase deficiency (237300), argininosuccinate synthetase deficiency, or citrullinemia (215700), argininosuccinate lyase deficiency, and arginase deficiency (207800). Erez (2013) reviewed argininosuccinic aciduria and progress in understanding it as a monogenic disorder that, like other inborn errors of metabolism, manifests as a multifactorial disorder at the phenotypic level. (207900) KEGG : 36 Arginosuccinicaciduria (ARGINSA) is an autosomal recessive disorder of the urea cycle that is caused by defects in argininosuccinate lyase. ARGINSA is characterized by mental and physical retardation, liver enlargement, skin lesions, dry and brittle hair showing trichorrhexis nodosa microscopically and fluorescing red, convulsions, and episodic unconsciousness.
