Combined malonic and methylmalonic aciduria


Type of disease: Rare conditions

Combined malonic and methylmalonic aciduria (CMAMMA) is an inherited condition in which certain chemicals accumulate in the blood and urine of affected individuals. People with CMAMMA can have a wide variety of symptoms. Children with CMAMMA can suffer from developmental delays and a failure to gain weight and grow (failure to thrive). In those who were identified as adults, symptoms may include psychiatric features and neurological problems that can mimic Alzheimer’s disease and multiple sclerosis. Recently, researchers have found that mutations in the ACSF3 gene cause CMAMMA.
