Mutations in Hcfc1 and Ronin result in an inborn error of cobalamin metabolism and ribosomopathy

Nature Communications, 2022
Combined methylmalonic acidemia (MMA) and hyperhomocysteinemias are inborn errors of vitamin B12 metabolism, and mutations in the transcriptional regulators HCFC1 and RONIN (THAP11) underlie some forms of these disorders. Here the authors generated mouse

Organoids for Metabolic Disease Modeling

Journal of Inherited Metabolic Disease, Volume 49, Issue 2, March 2026.
ABSTRACT Inherited metabolic diseases (IMDs) are a diverse group of rare genetic disorders that disrupt metabolic pathways, leading to severe clinical manifestations. Disease models ranging from complex animal models to simple in vitro systems have provided insights into IMDs, but each has limitations.

Mitochondrial Dysfunction in Propionic Acidemia: A Case‐Report and Review of the Literature

JIMD Reports, Volume 67, Issue 2, March 2026.
ABSTRACT Propionic acidemia is an inborn error of metabolism involving an enzymatic defect of propionyl‐CoA carboxylase that results in the build‐up of toxic metabolites which can induce metabolic decompensation. Secondary mitochondrial dysfunction in propionic acidemia has been commonly recognized; however, its clinical presentation and management are

The utility of methylmalonic acid, methylcitrate acid, and homocysteine in dried blood spots for therapeutic monitoring of three inherited metabolic diseases

Frontiers in Nutrition
BackgroudRoutine metabolic assessments for methylmalonic acidemia (MMA), propionic acidemia (PA), and homocysteinemia involve detecting metabolites in dried blood spots (DBS) and analyzing specific biomarkers in serum and urine.

Progress in RNA‐Targeted Therapeutics for Human Diseases

MedComm, Volume 7, Issue 2, February 2026.
RNA‐targeted therapies are revolutionizing molecular medicine by transitioning from a “protein‐centric” focus to an “RNA‐regulatory network” approach. Leveraging RNA's diverse roles in gene regulation, signaling, and epigenetic modifications, advanced platforms such as ASOs, siRNA, miRNA, mRNA, aptamers, shRNA, and CRISPR/Cas systems are enabling ...

Vitamin B12 and Reproductive Health: Clinical Insights, Emerging Mechanistic Understanding, and Nutritional Aspects

Molecular Reproduction and Development, Volume 93, Issue 2, February 2026.
ABSTRACT Epidemiological data from assisted reproductive technologies (ART) link vitamin B12 (VitB12) deficiency to shorter gestation, low birth weight, and reduced live birth rates. VitB12 also plays a critical role in fertility for both sexes by supporting gamete quality.

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 ...
