Glutaric Acidemia Type 2

Symptoms, Doctors, Treatments, Advances & More

Glutaric acidemia type II is an inherited disorder that interferes with the body's ability to break down proteins and fats to produce energy. Incompletely processed proteins and fats can build up in the body and cause the blood and tissues to become too acidic (metabolic acidosis).

Mutations in any of three genes, ETFA, ETFB, and ETFDH, can result in glutaric acidemia type II. The ETFA and ETFB genes provide instructions for producing two protein segments, or subunits, that come together to make an enzyme called electron transfer flavoprotein. The ETFDH gene provides instructions for making another enzyme called electron transfer flavoprotein dehydrogenase.

Glutaric acidemia type II is a very rare disorder; its precise incidence is unknown. It has been reported in several different ethnic groups.

This condition is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.
