When a low serum cobalamin (vitamin B12) concentration and methylmalonic aciduria were noted, the dog was given a supplement of parenteral cobalamin. In one previous report, a mild methylmalonic aciduria was identified in a dog alongside a diagnosis of L-2-HGA. This phenotype can be caused by either mutations in the AMN or CUBN genes (locus heterogeneity). A 12 week old female Labrador retriever dog with signs of progressive diffuse degeneration of the brain and spinal cord was found to have methylmalonic and malonic aciduria. In dogs there are reports of the use of L-carnitine 3 or riboflavin and phenobarbitone 22 with possible clinical improvement. Dogs: 415−1,193 nmol/L.

Serum cobalamin and methylmalonic acid concentrations in dogs with chronic gastrointestinal disease. Potassium wasting diuretics may result in renal K + conservation and excess H + excretion, causing aciduria. Summary: This gene encodes a protein that catalyzes the final step in the conversion of vitamin B (12) into adenosylcobalamin (AdoCbl), a vitamin B12-containing coenzyme for methylmalonyl-CoA mutase. However, if severe allergic reactions occur it may be advisable to switch to the alternate vaccine to complete the series. Podell, M. et al. In humans, the product of this gene is a vitamin B12-dependent enzyme which catalyzes the isomerization of methylmalonyl-CoA to succinyl-CoA, while in other species this enzyme may have different functions. It is a conjugate acid of a methylmalonate (1-). Affected infants can experience vomiting, dehydration, weak muscle tone (hypotonia), developmental delay, excessive … Laboratory results showed low serum cobalamin (Cbl) concentrations, anaemia, leucopenia and methylmalonic aciduria. Methylmalonic acidemia (MMA) is a rare and serious genetic disorder that affects multiple body systems. The patient was diagnosed with methylmalonic aciduria due to cobalamin malabsorption. PennGen. The patient responded well to parenteral cobalamin administration, and the urinary MMA levels normalized rapidly following instigation of treatment. If your body doesn't have enough vitamin B12, it will make extra amounts of MMA. In one previous report, a mild methylmalonic aciduria was identified in a dog along-side a diagnosis of L-2-HGA.2 However, the authors did Figure 2 Transverse MRI images of the brain demonstrating This phenotype can be caused by either mutations in the AMN or CUBN genes (locus heterogeneity). Adapted from the corresponding entry by John Fyfe in [OMIA 000565-9615]. 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. Defects in this gene are a cause of methylmalonic aciduria. Serum bile acid concentrations were normal, but an ammonia tolerance test (ATT) was abnormal. Methylmalonic acidemia with homocystinuria is caused by mutations in the MMADHC, LMBRD1 and ABCD4 genes. [provided by RefSeq, Jul 2008]. Dogs with a serum cobalamin concentration below RI have significantly higher serum MMA concentrations compared to dogs with normocobalaminemia, but serum MMA concentrations are increased in some (12%) normocobalaminemic dogs.26 In cobalamin‐deficient Shar‐Peis, where a suspected hereditary but late‐onset form of cobalamin deficiency with … Morgan L W & McConnell J (1999) Cobalamin deficiency associated with erythroblastic anemia and methylmalonic aciduria in a Border collie.

Combined malonic and methylmalonic aciduria (CMAMMA) is a disorder whose unwieldy name refers to the types of chemicals that accumulate in the blood and urine of affected individuals instead of being metabolized, or converted to energy, as they are in healthy people. These odds are derived as follows: If the dog being tested is a carrier, each puppy has a 1 of 2 (50%) chance of being affected. We used whole exome sequencing of a single patient with combined malonic and methylmalonic aciduria (CMAMMA) to identify mutations in ACSF3, a putative malonyl-CoA and methylmalonyl-CoA synthetase (MCS). VetGen. Methylmalonic acid is a dicarboxylic acid that is malonic acid in which one of the methylene hydrogens is substituted by a methyl group. You MUST send a urine sample. Due to a genetic defect, the body is unable to properly process certain parts of proteins, leading to the symptoms of the condition. Methylmalonic acidemia is an inherited disorder in which the body is unable to process certain proteins and fats (lipids) properly.
