Differential diagnoses mainly include other urea cycle disorders and organic acidurias. Amino acid profiles will distinguish CPS1D from argininosuccinic aciduria, citrullinemia type I and arginase deficiency while orotic acid in urine should help to distinguish from ornithine transcarbamylase deficiency. Another more recent differential diagnosis is hyperammonemic encephalopathy due to carbonic anhydrase VA deficiency.
