Disease & disorder

methylmalonic acidemia

MONDO:0002012

A genetically heterogenous inherited disorder characterized by abnormalities in the metabolism of lipids and proteins. Signs and symptoms usually appear early in life and vary from mild to life threatening. They include vomiting, dehydration, hypotonia, developmental delays, hepatomegaly, lethargy, intellectual disabilities, and chronic kidney disease.

Background context

Methylmalonic acidemias

Methylmalonic acidemias, also called methylmalonic acidurias, are a group of inherited metabolic disorders, that prevent the body from properly breaking down proteins and fats. This leads to a buildup of a toxic level of methylmalonic acid in body liquids and tissues. Due to the disturbed branched-chain amino acids (BCAA) metabolism, they are among the classical organic acidemias. Methylmalonic acidemias have varying diagnoses, treatment requirements, and prognoses, which are determined by the specific genetic mutation causing the inherited form of the disorder. The first symptoms may begin as early as the first day of life or as late as adulthood. Symptoms can range from mild to life-threatening. Some forms can result in death if undiagnosed or left untreated. Methylmalonic acidemias are found with an equal frequency across ethnic boundaries.
