Inborn Errors of Metabolism in the Era of Untargeted Metabolomics and Lipidomics. [PDF]

Metabolites, 2019
Inborn errors of metabolism (IEMs) are a group of inherited diseases with variable incidences. IEMs are caused by disrupting enzyme activities in specific metabolic pathways by genetic mutations, either directly or indirectly by cofactor deficiencies ...

Carnitine Inborn Errors of Metabolism [PDF]

Molecules, 2019
Carnitine plays essential roles in intermediary metabolism. In non-vegetarians, most of carnitine sources (~75%) are obtained from diet whereas endogenous synthesis accounts for around 25%. Renal carnitine reabsorption along with dietary intake and endogenous production maintain carnitine homeostasis.

Exploiting epigenetics for the treatment of inborn errors of metabolism [PDF]

Journal of Inherited Metabolic Disease, 2020
Gene therapy is currently considered as the optimal treatment for inborn errors of metabolism (IEMs), as it aims to permanently compensate for the primary genetic defect.

Inborn Errors of Metabolism Associated With Autism Spectrum Disorders: Approaches to Intervention

Frontiers in Neuroscience, 2021
Increasing evidence suggests that the autism spectrum disorder (ASD) may be associated with inborn errors of metabolism, such as disorders of amino acid metabolism and transport [phenylketonuria, homocystinuria, S-adenosylhomocysteine hydrolase ...

Targeted urine metabolomics with a graphical reporting tool for rapid diagnosis of inborn errors of metabolism

Journal of Inherited Metabolic Disease, 2021
The current diagnostic work‐up of inborn errors of metabolism (IEM) is rapidly moving toward integrative analytical approaches. We aimed to develop an innovative, targeted urine metabolomics (TUM) screening procedure to accelerate the diagnosis of ...

Validation of amplicon-based next generation sequencing panel for second-tier test in newborn screening for inborn errors of metabolism

Journal of Laboratory Medicine, 2021
Next generation sequencing (NGS) technology has allowed cost-effective massive parallel DNA sequencing. To evaluate the utility of NGS for newborn screening (NBS) of inborn errors of metabolism (IEM), a custom panel was designed to target 87 disease ...

Milestones in treatments for inborn errors of metabolism: Reflections on Where chemistry and medicine meet

American Journal of Medical Genetics. Part A, 2021
From Sir Archibald Garrod's initial description of the tetrad of albinism, alkaptonuria, cystinuria, and pentosuria to today, the field of medicine dedicated to inborn errors of metabolism has evolved from disease identification and mechanistic discovery

Aspartame and Phenylketonuria: an analysis of the daily phenylalanine intake of aspartame-containing drugs marketed in France

Orphanet Journal of Rare Diseases, 2023
Background Phenylketonuria (PKU) is a rare genetic metabolic disorder in which especially high phenylalanine (Phe) concentrations cause brain dysfunction.

Subcutaneous vitamin B12 administration using a portable infusion pump in cobalamin-related remethylation disorders: a gentle and easy to use alternative to intramuscular injections

Orphanet Journal of Rare Diseases, 2021
Background Cobalamin (cbl)-related remethylation disorders are a heterogeneous group of inherited disorders comprising the remethylation of homocysteine to methionine and affecting multiple organ systems, most prominently the nervous system and the bone ...

Technical Study of Automated High-Throughput High-Sensitive Ceruloplasmin Assay on Dried Blood Spots—Reinstate the Potential Use for Newborn Screening of Wilson Disease

International Journal of Neonatal Screening, 2022
In this study, we modified a fully automatic immunoassay on ceruloplasmin concentration on dried blood spots (DBS) to increase its analytical sensitivity in order to accurately differentiate newborns from true Wilson disease (WD) patients.
