WebSymptoms of hyperammonemia range from headache, nausea, vomiting, fatigue and confusion, to seizure activity. 5 Physical exam findings include encephalopathy, asterixis, ataxia, and in severe cases, coma. Plasma amino acids and urine organic acids can help differentiate between causes of urea cycle disorders. WebAug 8, 2024 · Ornithine transcarbamylase deficiency (OTCD) is an X-linked genetic disorder that prevents the breakdown and excretion of ammonia; this allows ammonia to rise to toxic levels and affect the central nervous system. The organ most involved in the processing of ammonia is the liver. Liver mitochondria are the primary site of the urea cycle. [1] WebMar 13, 2014 · A reduction in ornithine transport into the mitochondria results in orotic aciduria and deficiency of urea synthesis. In this situation, plasma levels of ornithine are high and can be reduced by a low-protein diet. Citrin deficiency and hyperammonemia may be included in UCDs as transporter defects. fhsis2021
