Novel Pathogenic Variant (c.580C>T) in the CPS1 Gene in a Newborn With Carbamoyl Phosphate Synthetase 1 Deficiency Identified by Whole Exome Sequencing
Diagnosis of the urea cycle disorder (USD) carbamoyl-phosphate synthetase 1 (CPS1) deficiency (CPS1D) based on only the measurements of biochemical intermediary metabolites is not sufficient to properly exclude other UCDs with similar symptoms. We report the first Korean CPS1D patient using whole exome sequencing (WES). A four-day-old female neonate presented with respiratory failure due to sev...
متن کاملTwo novel mutations in the CPS1 gene of a newborn with carbamoyl phosphate synthetase 1 deficiency identified by next-generation sequencing
Carbamoyl phosphate synthetase 1 deficiency (CPS1D) is a rare autosomal recessive hereditary disease which usually presents as lethal hyperammonemia. Here we report the case of a newborn infant with lethal hyperammonemia. Blood liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis showed increased concentrations of alanine, glutamine and histidine. Urine gas chromatography-mass spe...
متن کاملMolecular characterization of carbamoyl-phosphate synthetase (CPS1) deficiency using human recombinant CPS1 as a key tool.
The urea cycle disease carbamoyl-phosphate synthetase deficiency (CPS1D) has been associated with many mutations in the CPS1 gene [Häberle et al., 2011. Hum Mutat 32:579-589]. The disease-causing potential of most of these mutations is unclear. To test the mutations effects, we have developed a system for recombinant expression, mutagenesis, and purification of human carbamoyl-phosphate synthet...
متن کاملWhole Exome Sequencing Revealed a Novel GJB1 Pathogenic Variant and a Rare BSCL2 Mutation in Two Iranian Large Pedigrees with Multiple Affected Cases of Charcot-Marie-Tooth
Charcot-Marie-Tooth disease (CMT) is the most common hereditary neuropathy of the peripheral nervous system with a wide range of severity and age of onset. CMT patients share similar phenotypes which make it often impossible to identify the disease types based on clinical presentation and electrophysiological studies alone. In recent years, novel genetic diagnostic approaches such as whole exom...
متن کاملCell and Gene Therapy for Carbamoyl Phosphate Synthetase 1 Deficiency
Carbamoyl phosphate synthetase 1 (CPS1) is the first and rate-limiting enzyme in the urea cycle. CPS1 deficiency is a devastating condition, which is clinically characterized by periodic episodes of life-threatening hyperammonemia. Currently, there is no cure for CPS1 deficiency except for liver transplantation, which is limited by a severe shortage of donors and significant risk of mortality a...
