CSP: inherited errors in the metabolic reactions occurring in the liver that convert ammonia to urea, resulting from inborn genetic mutations.,MSH: Rare congenital metabolism disorders of the urea cycle. The disorders are due to mutations that result in complete (neonatal onset) or partial (childhood or adult onset) inactivity of an enzyme, involved in the urea cycle. Neonatal onset results in clinical features that include irritability, vomiting, lethargy, seizures, NEONATAL HYPOTONIA; RESPIRATORY ALKALOSIS; HYPERAMMONEMIA; coma, and death. Survivors of the neonatal onset and childhood/adult onset disorders share common risks for ENCEPHALOPATHIES, METABOLIC, INBORN; and RESPIRATORY ALKALOSIS due to HYPERAMMONEMIA.,NCI: A genetic inborn error of metabolism characterized by the deficiency of one of the enzymes necessary for the urea cycle. It results in accumulation of ammonia in the body.
