Case Report: Unusual Neurological Features of Leigh Syndrome due to m.8993T>G Pathogenic Variant in the MT‐ATP6 Gene

open access: yesAmerican Journal of Medical Genetics Part A, Volume 197, Issue 9, September 2025.
ABSTRACT The MT‐ATP6 gene m.8993T>G pathogenic variant has been associated with Leigh syndrome, especially in patients exhibiting a high degree of heteroplasmy. Although patients may present with a wide phenotypic spectrum, characteristic findings include bilateral, symmetric hyperintensities in the basal ganglia and brainstem on brain MRI ...

Personalized Genome‐Scale Modeling Reveals Metabolic Perturbations in Fibroblasts of Methylmalonic Aciduria Patients

open access: yesJournal of Inherited Metabolic Disease, Volume 48, Issue 5, September 2025.
ABSTRACT Cobalamin (vitamin B12) is an essential cofactor for two human enzymes, methionine synthase and methylmalonyl‐CoA mutase. Inborn errors of cobalamin metabolism (IECMs) are inherited genetic defects resulting in improper transport, modification, or utilization of cobalamin and include inherited methylmalonic acidurias, a group of IECMs most ...

Glycine N‐Acyltransferase Deficiency due to a Homozygous Nonsense Variant in the GLYAT: A Novel Inborn Error of Metabolism

open access: yesJIMD Reports, Volume 66, Issue 5, September 2025.
ABSTRACT The enzyme glycine N‐acyltransferase (GLYAT) plays a crucial role in detoxifying both xenobiotic and endogenous compounds that contain a carboxylic acid group, such as benzoic acid. Data on the impact of human GLYAT on the glycine conjugation pathway is limited and difficult to determine.

3D virtual biopsy of in vivo pH and metabolism using PRESS and semi‐LASER MRS of hyperpolarized 13C nuclei

open access: yesMagnetic Resonance in Medicine, Volume 94, Issue 3, Page 880-894, September 2025.
Abstract Purpose To develop and evaluate sequences for multi‐voxel magnetic resonance spectroscopy using hyperpolarized molecules. Methods A standard single voxel PRESS sequence was extended to acquire multiple voxels consecutively. Its SNR was compared against a 2D FID‐CSI with both 1H and hyperpolarized 13C nuclei in phantoms and in a healthy mouse ...
