Inborn errors of amino acid metabolism – from underlying pathophysiology to therapeutic advances

Disease Models & Mechanisms, 2023
ABSTRACT Amino acids are organic molecules that serve as basic substrates for protein synthesis and have additional key roles in a diverse array of cellular functions, including cell signaling, gene expression, energy production and molecular biosynthesis.

Moroccan Experience of Targeted Screening for Inborn Errors of Metabolism by Tandem Mass Spectrometry

Pediatric Reports, 2023
Background: Expanded newborn screening using tandem mass spectrometry (MS/MS) for inborn errors of metabolism (IEM), such as organic acidemias (OAs), fatty acid oxidation disorders (FAODs), and amino acid disorders (AAs), is increasingly popular but has ...

Toxic Metabolites and Inborn Errors of Amino Acid Metabolism: What One Informs about the Other

Metabolites, 2022
In inborn errors of metabolism, such as amino acid breakdown disorders, loss of function mutations in metabolic enzymes within the catabolism pathway lead to an accumulation of the catabolic intermediate that is the substrate of the mutated enzyme.

Renal replacement therapy in neonates with an inborn error of metabolism [PDF]

Korean Journal of Pediatrics, 2019
Hyperammonemia can be caused by several genetic inborn errors of metabolism including urea cycle defects, organic acidemias, fatty acid oxidation defects, and certain disorders of amino acid metabolism.

The Discovery of the Mode of Action of Nitisinone

Metabolites, 2022
This review briefly discusses the discovery of the mode of action of the triketone herbicide, 2-(2-nitro-4-trifluormethylbenzoyl)-1,3-cyclohexanedione and its use as a drug Nitisinone for the treatment of inborn errors of tyrosine metabolism.
