Found inside – Page 220A metabolic disorder characterized by high levels of methylmalonic acid in blood and urine due to defective reduction or transport of cobalamin. Symptoms ... In the most severe cases, symptoms begin almost immediately. When mutations in the MUT gene change the structure of methylmalonyl CoA mutase but do not eliminate its activity completely, patients are designated "mut-". doi:10.1097/MOP.0000000000000422, Marquard J, El scheich T, Klee D, et al. Isolated methylmalonic acidemia is caused by mutations (or mistakes) in the MMAA, MMAB, and MUT genes. This group of conditions is found in people of all racial and ethnic backgrounds. But it’s important to note that not everyone with MMA will have all these symptoms. Methylmalonic acid is an organic acid of which the blood levels are usually raised in case of a B12 deficiency. People with MMA should not fast or increase their intake of protein because this might trigger a decompensation. If an individual with MMA is ill (such as from a virus), it’s important that they decrease protein intake and receive additional fluids with sugar. Manoli I, Venditti CP. approximately 1 in 30,000 live births with a methylmalonic When serum vitamin B12 levels are low to normal (between 200-350pg/mL), an elevated serum MMA level (more than 0.4 micromol/L) is indicative of vitamin B12 deficiency. 2011;170(2):241-5. doi:10.1007/s00431-010-1313-5, Ma X, Zhang Y, Yang Y, et al.

Newborn screening identifies Methylmalonic acidemia is a complex disease that can cause a variety of different symptoms. The intensity of these symptoms varies based on the exact genetic mutation causing the disease. Metabolism takes place through a complicated and highly coordinated sequence of chemical reactions. infantile metabolic ketoacidosis, failure to thrive, and Deficiency should be confirmed by checking the level of a substance in the blood called methylmalonic acid. Another biomarker for vitamin B12 status is methylmalonic acid (MMA), as well as homocysteine, whose levels rise in vitamin B12 deficient patients. Due to a genetic defect, the body is unable to properly process certain parts of proteins, leading to the symptoms of the condition. Elderly Most types of methylmalonic acidemia are inherited in an autosomal recessive manner, meaning both parents of an affected child are carriers. This gene provides instructions for making an enzyme called methylmalonyl CoA mutase, which is responsible for one step in the breakdown of several amino acids (the building blocks of proteins), certain lipids, and cholesterol. Due to a genetic defect, the body is unable to properly process certain parts of proteins, leading to the symptoms of the condition. This is a new one to me. and Methylmalonate Metabolism.

Methylmalonic acidemia (MMA) refers to a group of inherited disorders in which the body is unable to process certain proteins and fats (lipids) properly. possible causes of mild methylmalonic acidemia and aciduria. Presenting a wide scope of problems caused by B12 deficiency, this comprehensive guide provides up-to-date medical information about symptoms, testing, diagnosis, and treatment. Patterns of brain injury in inborn errors of metabolism. People with this disease can't change, or "metabolize," a substance called called methymalonyl-coenzyme A. Carriers are asymptomatic. Ideally, people with MMA should see a specialist with experience in rare genetic diseases. There are different forms of methylmalonic acidemia, each with different causes and treatments. Therefore, methylmalonic acid begins to accumulate, as well as some other related substances. These compounds can be toxic when they build up in the body, leading to some of the symptoms of the disease. An elevated level of ammonia in the blood (hyperammonemia) may also be present. Individuals with methylmalonic acidemia can be divided into two groups: 1) patients with isolated MMA, where only methylmalonic acid is elevated 2) patients with combined defects who also have increased levels of homocysteine. Elevated serum levels of homocysteine (tHcy) 4 and methylmalonic acid (MMA) are frequently referred to in the literature as metabolic indicators of vitamin B-12 deficiency (1, 6, 16, 17, 20- 23). For example, an infant undergoing a decompensation might have symptoms such as:, Even with the best medical interventions, some people with MMA will experience decompensations from the disease.
