Argininosuccinic Aciduria


Argininosuccinic Aciduria, (Argininosuccinase Deficiency, Argininosuccinate Lyase Deficiency, ASL Deficiency) is an autosomal recessive disorder caused by a mutation in the ASL gene which codes for argininosuccinate lyase. It results in accumulation of citrulline, arginosuccinic acid, L-arginine, and L-glutamic acid in plasma as well as ammonia in blood. Infants are lethargic and unwilling to eat. They may develop seizures, coma, and failure to thrive as toxic ammonia accumulates.
