Ornithine Transcarbamylase Deficiency
Accumulation of ammonia in body tissues most commonly occurs in hepatic failure. However, it may also result from a specific deficiency of an enzyme of the urea cycle (Fig., 1). Severe hyperammonaemia has been reported with deficiencies of carbamyl phosphate synthetase (Freeman et al., 1964) and ornithine transcarbamylase (Russell et al., 1962; Levin and Russell, 1967). Some increase in blood a...
متن کاملAntepartum Ornithine Transcarbamylase Deficiency
Ornithine transcarbamylase deficiency (OTCD) is the most common type urea cycle enzyme deficiencies. This syndrome results from a deficiency of the mitochondrial enzyme ornithine transcarbamylase, which catalyzes the conversion of ornithine and carbamoyl phosphate to citrullin. Our case was a 28-year-old female diagnosed with OTCD following neurocognitive deficit during her first pregnancy. Alt...

متن کاملNitrogen Metabolism in Ornithine Transcarbamylase Deficiency
We developed a new technique that monitors metabolic competency in female heterozygotes for ornithine transcarbamylase deficiency (OTCD). The method uses mass spectrometry to measure conversion of 15 NH 4 Cl to [ 15 N]urea and [515 N]glutamine following an oral load of 15 NH 4 Cl. We found that heterozygotes converted significantly less NH 3 nitrogen to urea, with this difference being particul...
متن کاملIncrease of ornithine transcarbamylase protein in sparse-fur mice with ornithine transcarbamylase deficiency.
Ornithine transcarbamylase (OTCase, EC 2.1.3.3) a mitochondrial enzyme of the urea cycle catalyses the formation of citrulline from ornithine and carbamoyl phosphate. It has been purified from liver in 3 mammalian species: bovine [ 11, human [2] and rat [3,4] but not from mouse. We decided to purify mouse OTCase because the mouse is the only mammalian species in which two strains with an OTCase...
