Metabolic phenotype of methylmalonic acidemia in mice and humans: the role of skeletal muscle

BMC Medical Genetics, 2007
Background Mutations in methylmalonyl-CoA mutase cause methylmalonic acidemia, a common organic aciduria. Current treatment regimens rely on dietary management and, in severely affected patients, liver or combined liver-kidney transplantation.

An eye on long‐duration spaceflight: Controversies, countermeasures and challenges

Experimental Physiology, EarlyView.
Abstract Space flight‐associated neuroocular syndrome (SANS) is a consequence of long‐duration space flight and is detected in two‐thirds of astronauts. In‐flight, this can cause a change in the refraction of the eyes, requiring graded hypermetropic ‘superfocus adjustable’ glasses, optic nerve head oedema and choroidal folds.

Vitamin‐Responsive Disorders: From Molecular Basis to Clinical Presentation and Therapy

Journal of Inherited Metabolic Disease, Volume 49, Issue 4, July 2026.
ABSTRACT Vitamin‐dependent cofactors are essential for numerous metabolic reactions, and defects affecting their uptake, conversion, utilisation, or regeneration constitute a heterogeneous group of inherited metabolic disorders (IMDs). Although dietary vitamin intake is sufficient to sustain coenzyme synthesis in healthy individuals, it is insufficient

Cytosolic Phosphoenoylpyruvate Carboxykinase Deficiency: Clinical, Biochemical, and Genetic Features of Five Non‐Finnish Patients

American Journal of Medical Genetics Part A, Volume 200, Issue 6, Page 1192-1203, June 2026.
ABSTRACT Cytosolic phosphoenoylpyruvate carboxykinase (PEPCK‐C) is an essential, rate‐limiting enzyme in the gluconeogenesis pathway. PEPCK‐C deficiency presents with hypoglycaemia, hyperlactataemia and hepatopathy, and was first reported in association with bi‐allelic PCK1 variants in 2014.
