Amino Acid Metabolism in Liver Mitochondria: From Homeostasis to Disease

Metabolites
Hepatic mitochondria play critical roles in sustaining systemic nutrient balance, nitrogen detoxification, and cellular bioenergetics. These functions depend on tightly regulated mitochondrial processes, including amino acid catabolism, ammonia clearance

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.

35 Individuals With HUWE1‐Related Neurodevelopmental Disorder and Suggested Clinical Evaluations

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT HUWE1 (HECT, UBA, and WWE Domain Containing E3 Ubiquitin Protein Ligase1, OMIM 300697), located at Xp11.22, encodes a ubiquitin ligase that is highly conserved across species. Genetic variants in HUWE1 described in multiple independent studies cause X‐linked intellectual disability, including in the patients identified by Juberg, Marsidi, and ...

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)

Response of an Infant With Presumed Multiple Acyl‐CoA Dehydrogenase Deficiency (MADD) to Ketone Supplementation

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Multiple Acyl‐CoA Dehydrogenase Deficiency (MADD) is an autosomal recessive inborn error of metabolism caused by biallelic pathogenic variants in one of three known genes: ETFA, ETFB, and ETFDH. It can cause multisystem dysfunction, including cardiomyopathy in severe cases.

Use of a neuron-glia genome-scale metabolic reconstruction to model the metabolic consequences of the Arylsulphatase a deficiency through a systems biology approach

Heliyon, 2021
Metachromatic leukodystrophy (MLD) is a human neurodegenerative disorder characterized by progressive damage on the myelin band in the nervous system. MLD is caused by the impaired function of the lysosomal enzyme Arylsulphatase A (ARSA).

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).

Histidine Supplementation Stabilizes Hearing and Vision and Improves Growth in HARS1‐Related Autosomal Recessive Disorder Associated With Usher‐Like Symptoms

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Autosomal recessive HARS1‐related disorder (originally described as Usher syndrome type 3B) caused by a homozygous Y454S variant in the histidyl‐tRNA synthetase gene (HARS1) is characterized by progressive sensorineural hearing and vision loss and respiratory deterioration with risk for sudden death following febrile illnesses.

A Case of Multiple Mitochondrial Dysfunctions Syndrome 1 and Review of the Literature

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Multiple mitochondrial dysfunctions syndrome 1 (MMDS1, MIM #605711) due to NFU1 gene defects is an ultra‐rare autosomal recessive inborn error of metabolism associated with reduced function of NFU1 iron–sulfur cluster (ISC) scaffold protein.
