A mouse model of argininosuccinic aciduria: biochemical characterization.
Argininosuccinate lyase (AL) has several roles in intermediary metabolism. It is an essential component of the urea cycle, providing a pathway for the disposal of excess nitrogen in mammals. AL links the urea cycle to the tricarboxylic acid (TCA) cycle by generating fumarate. Finally, AL is required for the endogenous production of arginine. In this latter role it may function outside ureagenic...
متن کاملArgininosuccinic aciduria, an inborn error of amino acid metabolism.
It is probable that many, if not all, of the inherited ('inborn') metabolic disturbances result from a specific enzyme defect, arising from a single abnormal gene. Examples are now known of a number of such inherited defects, some involving amino acids, which result in a block of a metabolic pathway. For example, the normal pathway for the metabolism of phenylalanine and tyrosine is by a series...
متن کاملTreatment Approach of a Patient Affected by Both Argininosuccinic Aciduria and Methylmalonic Aciduria
Most of the inborn errors of metabolism (IEM) are autosomal recessively inherited and they are more frequent in the countries where consanguineous marriages are commonly practiced. Rarely, more than one IEM are seen in the siblings of one family or in the same sibling. Here we report a patient with both argininosuccinic aciduria (ASA) and methylmalonic acidemia (MMA) and our therapeutic approac...
متن کاملArgininosuccinic aciduria: clinical and biochemical phenotype findings in Malaysian children.
Argininosuccinic aciduria is an inborn error of the urea cycle caused by deficiency of argininosuccinate lyase (ASL). ASL-deficient patients present with progressive intoxication due to accumulation of ammonia in the body. Early diagnosis and treatment of hyperammonemia are necessary to improve survival and prevent long-term handicap. Two clinical phenotypes have been recognized--neonatal acute...
متن کاملArgininosuccinic Aciduria-A Rare Indication for Liver Transplant: Report of Two Cases.
Argininosuccinic aciduria is a urea cycle disorder caused by an argininosuccinate lyase enzyme deficiency that ends with nitrogen accumulation as ammonia. Argininosuccinic aciduria patients are at risk for long-term complications including poor neurocognitive outcome, hepatic disease, and systemic hypertension despite strict pharmacologic and dietary therapy. As the liver is the principle site ...
