2-Methyl-3-hydroxybutyric acidemia (2M3HBA)
2-Methyl-3-hydroxybutyric acidemia (2M3HBA) is an inborn error of metabolism, an inherited condition in which an enzyme, 2-methyl-3-hydroxybutyryl-CoA dehydrogenase, is either missing or not working well. In 2M3HBA the body is unable to properly break down certain fats and also the amino acid (part of protein) known as isoleucine. 2M3HBA is considered an organic acid condition because it can lead to a harmful amount of certain organic acids and toxins in the body. Symptoms can vary and may include changes in muscle tone, uncontrollable movements, developmental delay, loss of developmental milestones, vision problems, hearing loss, seizures, and/or other potential signs and symptoms. Males are generally more seriously affected than females. Support groups are available to help connect families living with this condition with others who have experience or expertise with this or similar conditions.
