Ornithine Transcarbamylase Deficiency

Ornithine transcarbamylase deficiency (OTCD) is the most prevalent genetic disorder within urea cycle disorders, characterized by X-linked inheritance and variable phenotypic expression. Homozygous males with severe neonatal onset present shortly after birth with hyperammonemia, while late-onset cases may display mild neurocognitive symptoms. The severity of OTCD ranges from potentially lethal to enduring neurocognitive deficits. Interdisciplinary healthcare management involving clinical providers, nurses, pharmacists, and dieticians significantly enhances patient outcomes. Although genetic testing is often confirmatory, recent challenges in diagnosis highlight the importance of clinical and biochemical suspicion. This activity reviews the comprehensive pathophysiology of OTCD, clinical presentation, and diagnostic evaluation, emphasizing the critical role of a coordinated interprofessional approach in optimizing clinical outcomes and reducing associated morbidity and mortality.
