title: [Citrullinemia type I with recurrent liver failure in a child].
abstract: Citrullinemia type I is an autosomal recessive disorder caused by mutation of the gene expressing ASS1 argininosuccinate synthetase, limiting enzyme of the urea cycle. The classic variants are associated with neonatal/infantile forms that cause hyperammonemia leading to death if treatment is not established. Initial symptoms of disorders of the urea cycle include neurological impairment with mild or moderate liver damage. We report a case of recurrent liver failure in an infant diagnosed with type I citrullinemia without severe neurological involvement that was referred to our center for liver transplantation. Acute liver failure can be caused by a wide range of disorders in which inborn errors of metabolism are included. Appropriate treatment of disorders of the urea cycle and in particular citrullinemia I can avoid the need for a transplant.
