Analysis of Catecholamines and Pterins in Inborn Errors of Monoamine Neurotransmitter Metabolism—From Past to Future

Cells, 2019
Inborn errors of monoamine neurotransmitter biosynthesis and degradation belong to the rare inborn errors of metabolism. They are caused by monogenic variants in the genes encoding the proteins involved in (1) neurotransmitter biosynthesis (like tyrosine

Long-Chain Polyunsaturated Fatty Acids in Inborn Errors of Metabolism [PDF]

, 2010
The treatment of children with inborn errors of metabolism (IEM) is mainly based on restricted dietary intake of protein-containing foods. However, dietary protein restriction may not only reduce amino acid intake, but may be associated with low intake ...

Detection of other inborn errors of metabolism in hyperphenylalaninemic babies picked up on narrow-spectrum screening programs

The Turkish Journal of Pediatrics, 2012
In many countries, neonatal screening programs have been unable to expand and have been limited to a few diseases. We highlight herein the opportunity available for the early detection of some inborn errors of metabolism (IEMs) in those countries ...

Quantitative amino acid analysis by liquid chromatography‐tandem mass spectrometry using low cost derivatization and an automated liquid handler

JIMD Reports, 2020
Amino acid analysis is central to newborn screening and the investigation of inborn errors of metabolism. Ion‐exchange chromatography with ninhydrin derivatization remains the reference method for quantitative amino acid analysis but offers slow ...

Diagnostic pitfalls in neonatal hypertyrosinemia: a case report

Life Sciences, Medicine and Biomedicine, 2023
Hypertyrosinemia results from abnormality in tyrosine metabolism. Acquired hypertyrosinemia is notably more common than inherited types and typically presents with profile suggestive of secondary aetiology on biochemical testing.

Metabolic Diet App Suite for inborn errors of amino acid metabolism

Molecular Genetics and Metabolism, 2016
An increasing number of rare inborn errors of metabolism (IEMs) are amenable to targeted metabolic nutrition therapy. Daily adherence is important to attain metabolic control and prevent organ damage. This is challenging however, given the lack of information of disorder specific nutrient content of foods, the limited availability and cost of specialty

Vitamin B2 enables regulation of fasting glucose availability

eLife, 2023
Flavin adenine dinucleotide (FAD) interacts with flavoproteins to mediate oxidation-reduction reactions required for cellular energy demands. Not surprisingly, mutations that alter FAD binding to flavoproteins cause rare inborn errors of metabolism (IEMs)

The Nutritional Significance of Inborn Errors of Amino Acid Metabolism

Annals of Nutrition and Metabolism, 1977
Inborn errors of metabolism affect the metabolism of 7 out of 8 essential amino acids and a number of non-essential ones. Dietary treatment has been applied with varying success. The wide variations in the severity of symptoms in this group of diseases are discussed.
