These intermediate breakdown products are particularly prone to affect the basal ganglia, causing many of the signs and symptoms of glutaric acidemia type 1.

Hum Genet, 4pp. From Wikipedia, the free encyclopedia. Clinical Synopsis Toggle Dropdown. Babies with glutaric acidemia type 1 often are born with unusually large heads macrocephaly. A possible way to prevent the build-up of 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.

The former results from carnitine deficiency, which can also give rise to myopathy, cardiomyopathy, and Reye-like hepatocerebral crisis, and the latter can occur during intercurrent illness even in carnitine-supplemented children. Ten had a severe dystonic-dyskinetic disorder, 1 had a mild hyperkinetic disorder, and 1 was asymptomatic.

Identification of two cases of glutaric aciduria type I through routine neonatal screening using liquid secondary adiduria tandem mass spectrometry abstract.

Outcome was evaluated in relationship to therapy and therapy-independent parameters. Christensen described experience with chorionic villus sampling for first-trimester diagnosis of this disorder.


CS1 Spanish-language sources es Infobox medical condition new. Parents and caregivers can provide a more interactive occupational therapy by enabling the child to use his or her own excessive postural muscle tone to his or her own advantage see picture; note the care with which minimal pressure is applied while ensuring safety.

One way to acutely cause depression or bulimia or anxiety in humans, in order to acuduria an individual’s vulnerability to those disorders, is to supplement with a formula with all or most amino acids except tryptophan.

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. Clinical treatment resulted in improvement and full recovery, respectively.

Among 64 unrelated patients with glutaric acidemia type I, Biery et al. The metabolic symptoms, such as hypoglycemia and metabolic acidosis, were minimal. To better understand mechanisms of striatal degeneration, Strauss et al. This page was last edited on 28 Decemberat Glutaric aciduria type I. CT changes preceded the onset of symptoms by 3 months. It thus follows that collagen breakdown and protein breakdown in general should be prevented by all possible means.

Biochem Med, 12pp. Endogenous catabolism of proteins could be an important route for glutaric acid production.

Glutaric aciduria type 1

Collagen, aciduia most abundant protein in the human body, requires great amounts of lysine, the most abundant amino acids in proteins. Pediatric Research, 48pp. Si continua navegando, consideramos que acepta su uso. Hospital General Universitario de Albacete. The condition glutrica inherited in an autosomal recessive pattern: Cystinuria Hartnup disease Iminoglycinuria Lysinuric protein intolerance Fanconi syndrome: A bonus to all MIMmatch users is the option to sign up for updates on caiduria gene-phenotype relationships.


Mutations in the GCDH’ gene prevent production of the enzyme or result in the production of a defective enzyme with very low residual activity, or an enzyme with relatively high residual activity but still phenotypic consequences.

It is important to consider GA-1 in the differential diagnosis of patients with spastic or dyskinetic cerebral palsy without a clear history of hypoxic events, as well as in patients with regression in neurological development. GDD has a distinctive pathological appearance due to the accumulation of glutaric acid GA3-hydroxyglutaric 3-OH-GA and glutaconic acids acicuria glutarylcarnitine in body fluids.

Neuropsychologic testing of 8 of 12 subjects demonstrated receptive language function to be superior to expressive language and motor function, although cognitive functions were less affected than motor functions.


Expert curators review the literature and organize it to facilitate your work. In some patients, the disease may appear acutely triggered by an infection between 6 and 18 months of age. Holmes Mortonthe Albert Schweitzer Prize for Humanitarianism laureate, is taking care of patients affected with GA1 and other metabolic diseases in this community in his Clinic for Special Children. In many areas, GA1 is included in newborn screening panels. Glutaric acidemia type 1 type 2 Hyperlysinemia Pipecolic acidemia Saccharopinuria.

Like many other organic acidemias, GA1 causes carnitine depletion.

GDD can exceptionally present with hypoglycemia or acidosis.
