Methylmalonic acid levels in serum, exosomes, and urine and its association with cblC type methylmalonic acidemia-induced cognitive impairment [PDF]

open access: yesFrontiers in Neurology, 2022
BackgroundThe cblC type methylmalonic acidemia is the most common methylmalonic acidemia (MMA) in China. The biochemical characteristics of this disease include elevated methylmalonic acid and homocysteine (HCY), increased propionylcarnitine (C3 ...

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

open access: yesFrontiers 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.

Elevated Urinary Methylmalonic Acid/creatinine ratio and Serum Sterol levels in Patients with Acute Ischemic Stroke

open access: yesRomanian Journal of Laboratory Medicine, 2018
Introduction: Sitosterolemia, defined as phytosterolemia, is a rare autosomal recessive disease characterized by elevated blood sterol levels. Our aim was to investigate serum plant sterols, methylmalonic acid, vitamin B12, oxidized-LDL and homocysteine ...

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]

open access: yesPLoS 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).

Relationship between methylmalonic acid and cobalamin in uremia [PDF]

open access: yesKidney International, 2000
Relationship between methylmalonic acid and cobalamin in uremia.To evaluate the requirement for routine supplementation with vitamin B12 and to study the effect of a change from injection to oral B12 supplementation, we examined the relationship between cobalamin and methylmalonic acid in plasma from 67 patients on chronic hemodialysis, all in regular ...

Mouse models for methylmalonic aciduria. [PDF]

open access: yesPLoS ONE, 2012
Methylmalonic aciduria (MMA) is a disorder of organic acid metabolism resulting from a functional defect of methylmalonyl-CoA mutase (MCM). MMA is associated with significant morbidity and mortality, thus therapies are necessary to help improve quality ...

Mechanisms of Microglial NLRP3 Inflammasome Activation by Methylmalonic Acid in Methylmalonic Acidemia

open access: yesMediators of Inflammation
Background Microglial activation is a critical pathogenic mechanism of neurological damage in methylmalonic acidemia (MMA). The NOD‐like receptor pyrin domain containing 3 (NLRP3) inflammasome is closely associated with neuroinflammatory processes.

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

open access: yes, 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 ...

Methylmalonic acid values in healthy Dutch children

open access: yesEuropean Journal of Nutrition, 2007
Plasma methylmalonic acid (MMA) is a specific marker for functional cobalamin deficiency. This deficiency can give rise to non-specific but serious symptoms in childhood such as developmental delay, convulsions and failure to thrive and may even lead to irreversible neurological damage.To analyse plasma MMA concentrations in Dutch children and to ...

Case Report: A Case of Late-Onset Combined Methylmalonic Acidemia and Hyperhomocysteinemia Induced by a Vegetarian Diet

open access: yesFrontiers in Pediatrics, 2022
Methylmalonic acidemia is a rare autosomal recessive metabolic disease. However, because of the atypical clinical symptoms, the type of late-onset methylmalonic academia is often misdiagnosed.
