Biochemical Testing Promotes Interpretation of Variants of Uncertain Significance in Prenatal Genetic Disease Testing in Four Organic Acidurias

Clinical Genetics, Volume 109, Issue 2, Page 211-217, February 2026.
This review demonstrates how amniotic fluid biochemical testing provides critical phenotypic evidence (ACMG PP4) for reclassifying variants of uncertain significance (VUS) in prenatal organic acidurias. Integrating metabolite analysis with genetic testing enhances diagnostic accuracy and enables informed clinical decisions for affected families ...

Polimorfismo de deleção de 19 pares de bases do gene dihidrofolato redutase (DHFR): risco materno para síndrome de Down e metabolismo do folato [PDF]

, 2010
CONTEXT AND OBJECTIVE: Polymorphisms in genes involved in folate metabolism may modulate the maternal risk of Down syndrome (DS). This study evaluated the influence of a 19-base pair (bp) deletion polymorphism in intron-1 of the dihydrofolate reductase ...

Methylmalonic acidemia with recurrent hemophagocytic lymphohistiocytosis: a case report and review of the literature

BMC Pediatrics
Background Methylmalonic acidemia is a rare autosomal recessive disorder of propionate catabolism characterized by the accumulation of propionic acid and methylmalonic acid caused by methylmalonyl-CoA mutase deficiency.

Monitoring Methylmalonic Aciduria by NMR Urinomics

Molecules, 2020
The paper reports on monitoring methylmalonic aciduria (MMA)-specific and non-specific metabolites via NMR urinomics. Five patients have been monitored over periods of time; things involved were diet, medication and occasional episodes of failing to ...

Neurological diagnoses in children potentially fulfilling the criteria for developmental coordination disorder

Developmental Medicine &Child Neurology, Volume 68, Issue 2, Page 251-262, February 2026.
In children potentially fulfilling the criteria for developmental coordination disorder (DCD), phenotypical assessment does not sufficiently predict the diagnostic outcome (i.e. DCD or an alternative diagnosis). Due to the lack of distinguishing clinical and diagnostic features and the high prevalence of genetic diagnoses in these patients, additional ...

Nutritional Management in Severe Methylmalonic and Propionic Acidemias: How Much Medical Food Is Too Much?

Journal of Inherited Metabolic Disease, Volume 49, Issue 1, January 2026.
ABSTRACT Methylmalonic acidemia (MMA) and propionic acidemia (PA) are inherited metabolic disorders affecting valine and isoleucine catabolism. Long‐term therapy mainly involves dietary protein restriction. An amino acid mixture (AAM, medical food) free of the precursor amino acids is frequently used, especially when protein intake does not reach World

From Control to Optimisation: Evolving Strategies in the Nutritional Management of Inborn Errors of Protein Metabolism

Journal of Inherited Metabolic Disease, Volume 49, Issue 1, January 2026.
ABSTRACT Undoubtedly the nutritional management of inborn errors of protein metabolism (IEPM) has improved since the early 1950s, but it is still associated with significant patient burden. The pace of development has not kept up with the increasing demands of the ‘real world’ or development in other areas of medicine. It is essential that research and

Hypoaminoacidemia and Pyroglutamic Aciduria: Potential Biomarkers in Malnutrition‐Related Hyperammonemia

JIMD Reports, Volume 67, Issue 1, January 2026.
ABSTRACT Hyperammonemia is a medical emergency, and the cause must be identified quickly in order to treat appropriately. Malnutrition is a known risk factor for hyperammonemia; however, there are limited reliable lab indicators used to identify malnutrition.

Causes of and diagnostic approach to methylmalonic acidurias [PDF]

, 2018
Summary: Several mutant genetic classes that cause isolated methylmalonic acidurias (MMAuria) are known based on biochemical, enzymatic and genetic complementation analysis. The mut0 and mut− defects result from deficiency of MMCoA mutase apoenzyme which
