Ring telefonnummer 1177 för sjukvårdsrådgivning dygnet runt. Elevated levels of methylmalonic acid (MMA) result from inherited defects of enzymes involved in MMA metabolism or inherited or acquired deficiencies of vitamin B12 (cobalamin) or its downstream metabolites. Acquired nutritional deficiencies are much more common than inherited defects and can be due to intestinal malabsorption, impaired digestion, ABSTRACT: Methylmalonate or propionate was i.v. infused into B12-deprived and control rats.

Propionic and methylmalonic acidemic patients have severe neurologic symptoms whose etiopathogeny is still obscure. Since increase of lactic acid is detected in the urine of these patients, especially during metabolic decompensation when high concentrations of methylmalonate (MMA) and propionate (PA … High homocysteine and methylmalonate among demented and non-demented elderly receiving vitamin-B12 prescription and home help service Hagnelius, Nils-Olof, 1953- (author) Örebro universitet,Hälsoakademin Wahlund, Lars-Olof (author) Karolinska Institutet, Neurotec Nilsson, Torbjörn K., 1956- (author) Örebro universitet,Hälsoakademin Chronic administration of methylmalonate on young rats alters neuroinflammatory markers and spatial memory Immunobiology . 2013 Sep;218(9):1175-83.

In only 16% of participants, P-MMA levels increased substantially, whereas 44  This test measures the amount of a substance called methymalonic acid (MMA) in your blood.

2021-04-02 · Methylmalonic acid is a substance produced when proteins, called amino acids, in the body break down. The health care provider may order this test if there are signs of certain genetic disorders, such as methylmalonic acidemia.

2021-01-19 · High Methylmalonic Acid Causes. Causes of high MMA include: B12 deficiency, most often due to a B12-poor diet, issues with nutrient absorption, or drugs that deplete B12 levels (e.g.

A high level of MMA can mean that you have a low level of B-12. Vitamin B-12 deficiency is  As a consequence, vitamin B12 deficiency may result in high concentrations of MMA and HCys.20 The sensitivity and specificity of elevated MMA concentrations   Serum methylmalonic acid (MMA) measurement is used to evaluate individuals with signs and symptoms associated with vitamin B12 deficiency1-7 or  and urinary methylmalonate (uMMA) were measured in methylmalonic acid ( MMA).6 – 8 In infants, vitamin B12 homocysteine was measured using high-. Assay for urinary methylmalonic acid by high-pressure liquid chromatography.

Developmental Delay Due To Methylmalonate Semialdehyde Dehydrogenase Deficiency Is also known as mmsdh deficiency, developmental delay due to Propionic and methylmalonic acidemic patients have severe neurologic symptoms whose etiopathogeny is still obscure. Since increase of lactic acid is detected in the urine of these patients, especially during metabolic decompensation when high concentrations of methylmalonate (MMA) and propionate (PA) are produced, it is possible that cellular respiration may be impaired in these individuals.

Succinate dehydrogenase inhibitor. Cited in 1 publication. A high level of MMA can mean that you have a low level of B-12. Vitamin B-12 deficiency is the most common cause of MMA production. Foods that can increase B-12 levels include red meats, shellfish, fish, dairy, and cereals fortified with the vitamin.

In one step of metabolism, vitamin B12 promotes the conversion of methylmalonyl CoA (a form of MMA) to succinyl Coenzyme A. High MMA concentrations in newborns, occasionally denoted as benign methylmalonic aciduria, may reflect impaired cobalamin function. Lifestyle , cardiovascular disease , neurologic disorders , folate deficiency , cobalamin deficiency ALDH6A1, also known as methylmalonate semialdehyde dehydrogenase (MMSDH), is a mitochondrial tetramer composed of 57.8 kDa subunits (Goodwin et al., 1989). It is involved in valine and pyrimidine catabolism and catalyzes the oxidative decarboxylation of malonate- and methylmalonate-semialdehyde to acetyl-CoA and propionyl-CoA, respectively.
