Abstract |
Ornithine transcarbamylase deficiency(OTCD), the most common inborn error of the urea cycle, is inherited in X-linked manner. In affected hemizygote males, OTCD manifests hyperammonemic coma that often leads to death during the newborn period. Our patient was at high risk for inborn error of urea cycle metabolism, since his two elder brothers died a few days after birth due to hyperammonemia. He was diagnosed as OTCD based on biochemical profiles and direct sequencing of the OTC gene. He has been managed with Ross metabolic protocol including protein restriction, administration of sodium benzoate, phenylacetate, arginine, citrulline, and diet therapy (Cyclinex-IⓇ) since birth. At the 8 months of age, we performed living-related liver transplantation(LRLT) using his father's left lateral segment. The patient’s serum ammonia level was restored to normal after LRLT without protein restriction. During postoperative follow up for 10 months, he was still in normal neurological and developmental status. |
