Summaries for Urea Cycle Disorder

GARD : 20 A urea cycle disorder is a genetic disorder that results in a deficiency of one of the six enzymes in the urea cycle. These enzymes are responsible for removing ammonia from the blood stream. The urea cycle involves a series of biochemical steps in which nitrogen, a waste product of protein metabolism, is changed to a compound called urea and removed from the blood. Normally, the urea is removed from the body through the urine. In urea cycle disorders, nitrogen builds up in the blood in the form of ammonia, a highly toxic substance, resulting in hyperammonemia (elevated blood ammonia). Ammonia then reaches the brain through the blood, where it can cause irreversible brain damage, coma and/or death. The onset and severity of urea cycle disorders is highly variable. The severity correlates with the amount of urea cycle enzyme function.

MalaCards based summary : Urea Cycle Disorder, also known as urea cycle disorders, inborn, is related to carbamoyl phosphate synthetase i deficiency, hyperammonemia due to and hyperornithinemia-hyperammonemia-homocitrullinuria syndrome. An important gene associated with Urea Cycle Disorder is NAGS (N-Acetylglutamate Synthase), and among its related pathways/superpathways are Metabolism and Viral mRNA Translation. The drugs Clotrimazole and Miconazole have been mentioned in the context of this disorder. Affiliated tissues include liver, cortex and brain, and related phenotypes are Decreased viability and Decreased viability

Disease Ontology : 12 An amino acid metabolic disorder that involves a deficiency of one of the enzymes in the urea cycle which is responsible for removing ammonia from the blood stream.
