Glutaric acidemia type 1 is an inherited disorder in which the body is unable to completely break down the amino acids lysine, hydroxylysine and tryptophan. La aciduria glutárica tipo I es una enfermedad neurometabólica, de herencia autosómico recesiva (1 caso/ ), caracterizada por discinesia y distonía. Glutaric acidemia I is an autosomal recessive metabolic disorder characterized by gliosis and neuronal loss in the basal ganglia and a progressive movement.
