  • Title: Intermittent hyperammonemic encephalopathy in a child with ornithine transcarbamylase deficiency.
    Author: Gulati S, Menon S, Kabra M, Kalra V.
    Journal: Indian J Pediatr; 2004 Jul; 71(7):645-7. PubMed ID: 15280615.
    Abstract:
    Ornithine transcarbamylase (OTC) deficiency is an X-linked disorder and the most common inherited cause of hyperammonemia. Clinical manifestations are more severe in hemizygous males who often present in neonatal period. Heterozygous females may be asymptomatic until juvenile or adulthood. Fluctuating concentration of ammonia, glutamine and other excitotoxic amino acids result in a chronic or episodically recurring encephalopathy. The authors report a heterozygous female with OTC deficiency who presented with recurrent encephalopathy.
