Genetic testing is necessary for correct diagnosis and treatment in patients with isolated methylmalonic aciduria: a case report

BMC Pediatrics, 2021
Background Isolated methylmalonic aciduria can be caused by pathogenic mutations in the gene for methylmalonyl-CoA mutase or in the genes encoding enzymes involved in the intracellular metabolism of cobalamin.

Simultaneous determination of 3-hydroxypropionic acid, methylmalonic acid and methylcitric acid in dried blood spots: Second-tier LC-MS/MS assay for newborn screening of propionic acidemia, methylmalonic acidemias and combined remethylation disorders. [PDF]

PLoS ONE, 2017
Increased propionylcarnitine levels in newborn screening are indicative for a group of potentially severe disorders including propionic acidemia (PA), methylmalonic acidemias and combined remethylation disorders (MMACBL).

Decrease of disease‐related metabolites upon fasting in a hemizygous knock‐in mouse model (Mut‐ko/ki) of methylmalonic aciduria

JIMD Reports, 2021
Methylmalonyl‐CoA mutase (MMUT) is part of the propionyl‐CoA catabolic pathway, responsible for the breakdown of branched‐chain amino acids, odd‐chain fatty acids and the side‐chain of cholesterol.

The relationship between exacerbated diabetic peripheral neuropathy and metformin treatment in type 2 diabetes mellitus

Scientific Reports, 2021
Metformin-treated diabetics (MTD) showed a decrease in cobalamin, a rise in homocysteine, and methylmalonic acid, leading to accentuated diabetic peripheral neuropathy (DPN). This study aimed to determine whether or not metformin is a risk factor for DPN.

Gene identification for the cblD defect of vitamin B12 metabolism [PDF]

, 2008
Background Vitamin B12 (cobalamin) is an essential cofactor in several metabolic pathways. Intracellular conversion of cobalamin to its two coenzymes, adenosylcobalamin in mitochondria and methylcobalamin in the cytoplasm, is necessary for the ...
