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

open access: yesCells, 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

Inborn errors of metabolism: a clinical overview [PDF]

open access: yes, 1999
CONTEXT: Inborn errors of metabolism cause hereditary metabolic diseases (HMD) and classically they result from the lack of activity of one or more specific enzymes or defects in the transportation of proteins.

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

open access: yesThe 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

open access: yesJIMD 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

open access: yesLife 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.

Metabolomics of dietary fatty acid restriction in patients with phenylketonuria [PDF]

open access: yes, 2012
Patients with phenylketonuria (PKU) have to follow a lifelong phenylalanine restricted diet. This type of diet markedly reduces the intake of saturated and unsaturated fatty acids especially long chain polyunsaturated fatty acids (LC-PUFA).

Vitamin B2 enables regulation of fasting glucose availability

open access: yeseLife, 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)

Diagnosis of inborn errors of metabolism within the expanded newborn screening in the Madrid region

open access: yesJIMD Reports, 2022
We present the results of our experience in the diagnosis of inborn errors of metabolism (IEM) since the Expanded Newborn Screening was implemented in our Region. Dried blood samples were collected 48 h after birth.

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

open access: yes, 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 ...
