This paper concerns with two autopsied cases of siblings who died from cerebral disturbances. In these patients hyperammonemia developed in the neonatal phase due to carbamyl phosphate synthetase I (CPS I) deficiency. The patient in Case 1 was admitted 2 days after birth because of oliguria and vomiting. Hyperammonemia developed and she died on the 43rd day. In Case 2 hyperammonemia developed from the 2nd day after birth and she expired on the 42nd day. In both cases the diagnosis of CPS I deficiency was established from autopsy findings of the liver.

D001921 Brain The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM. Encephalon
D002222 Carbamoyl-Phosphate Synthase (Ammonia) An enzyme that catalyzes the formation of carbamoyl phosphate from ATP, carbon dioxide, and ammonia. This enzyme is specific for arginine biosynthesis or the urea cycle. Absence or lack of this enzyme may cause CARBAMOYL-PHOSPHATE SYNTHASE I DEFICIENCY DISEASE. EC 6.3.4.16.

D000592 Amino Acid Metabolism, Inborn Errors Disorders affecting amino acid metabolism. The majority of these disorders are inherited and present in the neonatal period with metabolic disturbances (e.g., ACIDOSIS) and neurologic manifestations. They are present at birth, although they may not become symptomatic until later in life.
