Automated Screening for Three Inborn Metabolic Disorders: A Pilot Study [PDF]

, 2006
Background: Inborn metabolic disorders (IMDs) form a large group of rare, but often serious, metabolic disorders. Aims: Our objective was to construct a decision tree, based on classification algorithm for the data on three metabolic disorders, enabling ...

Detecting the Difficult: An Intronic NPC1 Variant Hiding in Plain Sight

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT An illustration of the importance of manual data review for identifying rare intronic variants adjacent to homopolymers is presented here. A 14‐year‐old male with Niemann‐Pick Type C disease confirmed biochemically was only found to have a heterozygous pathogenic variant by molecular analysis. A manual review of the Next Generation Sequencing (

Quantitation of non-derivatized free amino acids for detecting inborn errors of metabolism by incorporating mixed-mode chromatography with tandem mass spectrometry

Journal of Mass Spectrometry and Advances in the Clinical Lab, 2022
Introduction: Amino acids are critical biomarkers for many inborn errors of metabolism, but amino acid analysis is challenging due to the range of chemical properties inherent in these small molecules.

Infant mortality in Brazil attributable to inborn errors of metabolism associated with sudden death: a time-series study (2002–2014)

BMC Pediatrics, 2019
Background The literature suggests that 0.9 to 6% of infants who die unexpectedly may have had a metabolic disorder. At least 43 different inborn errors of metabolism (IEMs) have been associated with sudden death (SUDI).

Severity of effect considerations regarding the use of mutation as a toxicological endpoint for risk assessment: A report from the 8th International Workshop on Genotoxicity Testing (IWGT)

Environmental and Molecular Mutagenesis, EarlyView.
Abstract Exposure levels without appreciable human health risk may be determined by dividing a point of departure on a dose–response curve (e.g., benchmark dose) by a composite adjustment factor (AF). An “effect severity” AF (ESAF) is employed in some regulatory contexts.

Diagnosis and therapeutic monitoring of inborn errors of metabolism in 100,077 newborns from Jining city in China

BMC Pediatrics, 2018
Background Mandatory newborn screening for metabolic disorders has not been implemented in most parts of China. Newborn mortality and morbidity could be markedly reduced by early diagnosis and treatment of inborn errors of metabolism (IEM).

Orotic Aciduria [PDF]

, 2018
Orotic acid is an intermediate found in the pathway for pyrimidine synthesis. The mitochondrial enzyme dihydroorotate dehydrogenase (DHODH) catalyzes the production of orotic acid by the conversion of the compound dihydroorotate to orotic acid.

EPIDEMIOLOGY, PATHOPHYSIOLOGY, AND HINDRANCE OF UREA CYCLE ERROR OF METABOLISM [PDF]

, 2021
Inborn errors of metabolism (IEMs) are a class of genetic disorders that are rare individually, but collectively they occur in common terms exhibiting an average prevalence of 1 in 1000 individuals.

Inherited metabolic epilepsies–established diseases, new approaches

Epilepsia Open, EarlyView.
Abstract Inherited metabolic epilepsies (IMEs) represent the inherited metabolic disorders (IMDs) in which epilepsy is a prevailing component, often determining other neurodevelopmental outcomes associated with the disorder. The different metabolic pathways affected by individual IMEs are the basis of their rarity and heterogeneity.

Ketogenic diet in action: Metabolic profiling of pyruvate dehydrogenase deficiency

Molecular Genetics and Metabolism Reports, 2023
The pyruvate dehydrogenase complex serves as the main connection between cytosolic glycolysis and the tricarboxylic acid cycle within mitochondria. An infant with pyruvate dehydrogenase complex deficiency was treated with vitamin B1 supplementation and a
