Angelman syndrome and isovaleric acidemia: What is the link?

Molecular Genetics and Metabolism Reports, 2015
We report a toddler affected with Angelman syndrome and isovaleric acidemia (IVA). Such association was due to paternal uniparental isodisomy (UPD) of chromosome 15 in which the proband inherited two paternal copies of an IVA gene point mutation. As both

An OGT Missense Variant With Impaired Enzyme Activity in a Child With Severe Developmental Delay and Hepatoblastoma

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT O‐GlcNAc transferase (OGT) and its antagonist O‐GlcNAcase (OGA) regulate protein O‐GlcNAcylation, a highly conserved post‐translational modification involved in metabolic sensing. Pathogenic variants in the OGT gene cause an X‐linked congenital disorder of glycosylation (OGT‐CDG) presenting developmental delay, hypotonia, intellectual ...

Variants in AKR1D1 and Infant Mortality: Should Bile Acid Screening be a Routine Part of Newborn Screening?

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Biallelic pathogenic variants in AKR1D1 cause Δ4‐3‐oxosteroid 5β‐reductase deficiency, disrupt bile acid synthesis, and result in Congenital Bile Acid Synthesis defect type 2 (CBAS2). CBAS2 presents in infancy with cholestasis, coagulopathy, and failure to thrive.

Dissociation of AGAT, GAMT and SLC6A8 in CNS: Relevance to creatine deficiency syndromes

Neurobiology of Disease, 2010
AGAT and GAMT, the two enzymes of the creatine synthesis pathway, are well expressed within CNS, suggesting autonomous brain creatine synthesis. This contradicts SLC6A8 deficiency, which causes creatine deficiency despite CNS expression of AGAT and GAMT.

Evaluation of earlier versus later dietary management in long-chain 3-hydroxyacyl-CoA dehydrogenase or mitochondrial trifunctional protein deficiency::a systematic review [PDF]

, 2019
Background: Mitochondrial trifunctional protein (MTP) and long-chain 3-hydroxyacyl-CoA dehydrogenase (LCHAD) deficiencies are rare fatty acid β-oxidation disorders. Without dietary management the conditions are life-threatening. We conducted a systematic

Evaluation of a modified triple‐combination anesthesia using dexmedetomidine in mice

Animal Models and Experimental Medicine, EarlyView.
Development of a modified ketamine‐free anesthetic (dMMB) using dexmedetomidine. To improve the safety and recovery profile of conventional MMB, we developed dMMB by replacing medetomidine with dexmedetomidine. This ketamine‐free formulation showed comparable anesthetic depth and enhanced thermoregulation, avoiding unnecessary isomers for safer use ...

Molecular characterization of phenylketonuria patients from the North Region of Brazil: State of Pará

Molecular Genetics & Genomic Medicine, 2023
Background Phenylketonuria (PKU) is an autosomal recessive disease resulting from a deficiency of the enzyme phenylalanine hydroxylase (PAH). Hyperphenylalaninemias (HPA) due to PAH deficiency are accompanied by a wide variety of clinical, biochemical ...

Treatment of inborn errors of metabolism [PDF]

Molecular Cytogenetics, 2014
Inborn errors of metabolism (IEM), though individually rare are collectively common. Average incidence of 50+ common IEMs is considered to be approx 1 in 1,000 live births. With annual birth rate of approximately 25 million babies in India, we can expect at least 25,000 babies being born with IEM in India and hence it is a significant burden to the ...
