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.

Ada Hamosh – updated: Diagnostic methods Presymptomatic detection can be offered through routine newborn screening programs implemented in some countries. Neural Transm Gen Sect. Laboratory studies showed decreased long-chain acylcarnitines and high excretion of 3-hydroxyglutaric acid, but urinary glutaric acid excretion was normal.

Two children died in a state of hyperthermia. A possible way to prevent the build-up hlutarica metabolites is to limit lysine and hydroxylysine degradation, as lysine is one of the most abundant amino acids and tryptophan is one of the least abundant amino acids.

Normally in MRI the Sylvian fissure is operculated, but in glutaric acidemia type 1, it is not operculated. Glutaryl-CoA dehydrogenase GCDH deficiency GDD is an autosomal recessive neurometabolic disorder clinically characterized by encephalopathic crises resulting in striatal injury and a severe dystonic dyskinetic movement disorder. All but 1 had severe impairment of psychomotor development and abnormalities on T2-weighted MRI, acidria bilateral hyperdensities of basal ganglia, atrophy of the temporal lobe, or extensive white matter hypodensities.

Glutaric acidemia type 1 occurs in approximately 1 of every 30, to 40, births. The other patient developed headache, vertigo, and gait disturbance at age 15 years following an upper respiratory tract infection. Vegetarian diets and, for younger children, breastfeeding [13] are common ways to limit protein intake without endangering tryptophan transport to the brain.

Among 16 pregnancies, 4 were predicted to represent an affected fetus; in 3 of the affected cases, GCDH activity was measured in both uncultured and cultured chorionic cells and the correct diagnosis was established by both measurements. An Esp Pediatr, 4pp. Despite spastic diplegia and moderate choreoathetosis, he had normal intelligence and regularly worked in a carriage and harness repair shop.

Like many other organic acidemias, GA1 causes carnitine depletion. In 10 patients, the disorder was first manifest between 3 and 18 months during an acute infectious illness.

Hence, the initial presentation acicuria resemble viral encephalitis or ADEM. Glutaric aciduria type 1 of the Amish. GDD has a distinctive pathological appearance due to the accumulation of glutaric acid GA3-hydroxyglutaric 3-OH-GA and glutaconic acids and glutarylcarnitine in body fluids.


The above changes are not necessarily seen in less severely affected children. The consequence is acute tryptophan depletion ATD in the brain and a consecutive lowering of serotonin synthesis.

In a discussion of the natural history of GA I, Strauss et al. Several mutations were found in more than one patient, but no one prevalent mutation was detected in the general population. Treatment given after the appearance of symptoms was not associated with a better clinical outcome or fewer motor deficits. Unfortunately, it is not acidutia to produce. Specialised Social Services Eurordis directory. GDD can exceptionally present with hypoglycemia or acidosis.

Use of guidelines improves the neurological outcome in glutaric aciduria type 1. J Pediatr,pp. GA1 was considered as a “treatable disease”. Clinical treatment resulted in improvement and full recovery, respectively.

In the Amish community, where GA1 is overrepresented Morton,patients with GA1 did not and still don’t receive tryptophan-free formulas, neither as the sole source of amino acids, nor as a supplement to protein restriction.

The aiduria patient was a year-old man who was normal until age 3 months when, after a period of irritability and poor feeding on day 7 of a varicella infection, he experienced an acute, afebrile episode of tonic posturing glufarica thereafter became flaccid and unresponsive.
