ABSTRACT: Background
Ornithine transcarbamylase deficiency (OTCD) is the most common urea cycle disorder (UCD), caused by a deficiency of the OTC enzyme, leading to the accumulation of toxic ammonia in the blood. Neonatal-onset OTCD is associated with high mortality and severe neurodevelopmental impairments. Symptoms are often non-specific and can mimic neonatal sepsis. If untreated, the condition can rapidly progress to neurological damage. Early diagnosis and prompt intervention are crucial for improving survival and long-term outcomes.Case description
We report a case of a 9-day-old male infant diagnosed with neonatal-onset OTCD, who presented with lethargy and poor feeding. Initial ammonia levels were found to be elevated at 428 µmol/L, prompting the initiation of supportive care
