Argininosuccinic Acid Lyase Deficiency (ASA)

This acute illness protocol is a guideline for healthcare professionals treating the sick infant/child who has previously been diagnosed with argininosuccinic acidemia (ASA), a urea cycle defect (UCD). The protocol was developed at Boston Children’s Hospital under the direction of Dr. Harvey Levy, Senior Physician in Medicine/Genetics and Dr. Jonathan Picker, Fragile X Program Director.

Hyperammonemic crises in infants/children with UCD are medical emergencies and must be treated as such to avoid death or serious brain injury.
