In 1 case in which the fetus was unaffected, glutaric acid was not detected in the amniotic fluid at amniocentesis 15 weeks and the glutaryl-CoA dehydrogenase activity of cultured amniotic cells was normal.
Glutaric aciduria type 1 – Wikipedia
Ascorbic acid, the main hydroxyl radical quencher, works as the cofactor providing the hydroxyl radical required to collagen cross-linking; lysine thus becomes hydroxylysine. Among 64 unrelated patients with glutaric acidemia type I, Biery et al.

A slowly progressive dyskinetic disorder developed in 1 subject despite adequate early dietary treatment. Like many other organic acidemias, GA1 causes carnitine depletion.
These intermediate breakdown products are particularly prone to affect the basal ganglia, causing many of the signs and symptoms of glutaric acidemia type 1. Outcome was evaluated in relationship to therapy and therapy-independent parameters.

According to following the guidelines of Kolker et al. In patients who had a precipitating illness, gluarica age at onset did not predict the outcome.
Differential diagnosis GDD is often misdiagnosed. Stress caused by infection, fever or other demands on the body may lead to worsening of the signs and symptoms, with only partial recovery.
Amongst patients who had been reported to have GA1, were symptomatic two thirds ; being symptomatic was seen as an indication of ” low treatment efficacy “. Brain imaging showed increased signals in the lenticular nuclei. GDD can exceptionally present with hypoglycemia or acidosis. Hum Mol Genet, 4pp. Daily management comprises a low lysine diet, carnitine supplementation in association with prompt emergency treatment during intercurrent illness.
The findings implicated mitochondrial fatty acid metabolism as an important pathway in the development of dystonia, and Marti-Masso et al. The glutaric aciduria was increased by oral administration of L-lysine, which is metabolized through glutaryl-CoA, and was decreased by reduced protein intake. Diagnostic methods Presymptomatic detection can be offered through routine newborn screening programs implemented in some countries.

InfancyNeonatal ICD J Peddiatr,pp. Brain Dev, 15pp. Glutaric aciduria tipe I: Some individuals with glutaric acidemia have developed bleeding in the brain or eyes that could be mistaken for the effects of child abuse. High levels of glutaric acid were seen in the spinal fluid of all these patients.
Evidence of two groups of patients, genetically and biochemically distinct.
A common cause of episodic encepha-lopthy and spastic paralysis in the Amish of Lancaster country, Pensylvania. Glutaric acidemia type 1 or ” glutaric aciduria “, ” GA1 “, or ” GAT1 ” is an inherited disorder in which the body is unable to completely break down the amino acids lysinehydroxylysine and tryptophan. GA1 can be described as a metabolic disordera neurometabolic disease, a cerebral palsy or a basal ganglia disorder it is also misdiagnosed as shaken baby syndrome.
