Under recognition of late onset ornithine transcarbamylase deficiency.
Late onset ornithine transcarbamylase deficiency (McKusick 311250) is reported in four Finnish patients, two boys and two heterozygous girls. The subtle onset and course of ornithine transcarbamylase deficiency emphasises the need for plasma ammonia and amino acid measurements in clinical situations suggesting a disorder of this nature.
متن کاملFatal hyperammonaemia due to late-onset ornithine transcarbamylase deficiency.
In this case report we describe a 67-year-old male, admitted to the ICU with pneumonia who unexpectedly developed a fatal coma due to hyperammonaemia. At postmortem the diagnosis late-onset ornithine transcarbamylase deficiency was made. The non-specific clinical presentation, the rapid deterioration and incidentally the fatal outcome all underline the importance of recognition and knowledge of...
متن کاملLate-onset ornithine transcarbamylase deficiency: An under recognized cause of metabolic encephalopathy
INTRODUCTION Ornithine transcarbamylase deficiency is the most common inherited disorder of the urea cycle, has a variable phenotype, and is caused by mutations in the OTC gene. We report three cases of ornithine transcarbamylase deficiency to illustrate the late-onset presentation of this disorder and provide strategies for diagnosis and treatment. The patients were maternal first cousins, pre...
متن کاملOrnithine 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...
