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.

Unfortunately, it is not free to produce. In an affected infant with glutaric aciduria, Mandel et al. Acute subdural hemorrhage can occur after minor head trauma and in some instances is accompanied by retinal hemorrhages.

GA1 was considered as a “treatable disease”. Two children died in a state of hyperthermia.

Case 1 Case 1. Imaging, therefore, has an important role to play as the MRI features can be characteristic. The other patient developed headache, vertigo, and gait disturbance at age 15 years following an upper respiratory tract infection. Glutaric acidemia type 1 type 2 Hyperlysinemia Pipecolic acidemia Saccharopinuria. Glutaric aciduria type 1 is a rare organic aciduria, with an estimated prevalence of 1 innewborns 2.

We need long-term secure funding to provide you the information that you need at your fingertips. J Inherit Metab Dis. Subsequent evaluation revealed increased urinary glutaric acid and compound heterozygosity for mutations in the GCDH gene.

Age at symptom onset predicts severity of motor impairment and clinical outcome of glutaric acidemia type 1. For all other comments, please send your remarks via contact us. Endogenous catabolism of proteins could be an important route for glutaric acid production.

Glutaric aciduria type 1

It is thus important to investigate all cases of macrocephaly of unknown origins for GCDH deficiency, [2] [3] given the importance of the early diagnosis of GA1. It is much more common in the Amish community and in the Ojibway population of Canadawhere up to 1 in newborns may be affected.

We conclude that amino and organic acids in urine should be investigated in all children with progressive macrocephaly of unknown etiology to rule out glutaric aciduria type I.

In this context, the radiologist needs to be familiar with the imaging findings of glutaric aciduria type I so that an erroneous diagnosis of non-accidental injury is not made. A subset of patients present with an insidious onset without episodes of acute deterioration 1and others still present as adults with progressive encephalopathy, or are asymptomatic 3.

In the Amish community, where GA1 axiduria 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 analyses showed that in patients who did not have glutarjca precipitating illness before the first appearance of motor symptoms, the age at onset was significantly associated with the severity of motor impairments and overall clinical outcome.

Lateral sulcus becomes non operculated. Type I glutaric aciduria, part 1: In older patients, exercise intolerance, hypoglycemia, and seizures often developed. Recommendations included a lysine-restricted diet to reduce the accumulation of the neurotoxic metabolites glutaric acid, 3-hydroxyglutaric acid, and glutaryl-CoA deriving from the precursor amino acid lysine; the supplementation of carnitine to prevent secondary carnitine depletion, to facilitate production of the nontoxic C5DC, and to replenish the intracellular free coenzyme A pool; and the intermittent and stepwise intensification of metabolic treatment using a high-calorie, low- or no-protein emergency treatment protocol acidurua putatively threatening episodes such as infectious disease to prevent striatal injury.

Despite early diagnosis, one-third of Amish infants with glutaryl-CoA dehydrogenase deficiency developed striatal lesions that leave them permanently disabled. Glutaric aciduria type 1, in many cases, can be defined as a cerebral palsy of genetic origins. Remarkably, in both sib pairs, 1 child was asymptomatic. OMIM is intended for use primarily by physicians and other professionals concerned with genetic disorders, by genetics researchers, and by advanced students in science and medicine.


Holmes Mortonthe Albert Schweitzer Prize for Humanitarianism laureate, is taking care of patients affected with GA1 and other metabolic diseases gputarica this community in his Clinic for Special Children.


With the expansion of convexity subarachnoid spaces, the coursing bridging veins are susceptible to rupture with only minor trauma, and these patients may present with subdural hemorrhages. Several mutations were found in more than one patient, but glutarkca one prevalent mutation was detected in the general population.

HIV encephalopathy- AIDS dementia complexpneumococcal meningitishypoadrenal crisis, methylmalonic acidemiapropionic acidemiamiddle cerebral artery occlusion, hypertensive vasculopathy, acute Mycoplasma pneumoniae infection, 3-nitropropionic acid intoxication, late onset familial dystoniacerebrovascular abrupt and severe neonatal asphyxia “selective neuronal necrosis”.

Check for errors and try again. Outcome was evaluated in relationship to therapy and therapy-independent parameters.

Late-onset neurologic disease in glutaryl-CoA dehydrogenase deficiency. Other grey matter structures can be affected, e. Adult onset glutaric aciduria type I presenting with a leukoencephalopathy. Laboratory studies showed decreased long-chain acylcarnitines and high excretion of 3-hydroxyglutaric acid, but urinary glutaric acid excretion was normal. 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.

After a positive screening result, confirmatory testing is performed. Clinical course, early diagnosis, and prevention of disease in glutaril-CoA dehydrogenase deficiency. Worldwide prevalence is estimated at 1 inbirths.

This excludes, however, patients who already suffered an encephalopathic crisis, for whom the prognosis is more related to the treatment of their acquired disorder striatal necrosis, frontotemporal atrophy.
