This enzyme is involved in degrading the amino acids lysinehydroxylysine and tryptophan. A possible way to qciduria 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. D ICD – 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.

Glutaric aciduria type 1

Subsequent evaluation revealed increased urinary glutaric acid and compound heterozygosity for mutations in the GCDH gene. Metabolism of radioactive glutaryl-CoA was deficient in white cells, a result compatible with inherited deficiency of glutaryl-CoA dehydrogenase Goodman et al.

Glutaryl-CoA dehydrogenase deficiency in Spain: Hum Genet,pp. High risk screening, neonatal screening and a diagnosis of macrocephaly were the ways to identify bearers of the GCDH’ defective gene who weren’t frankly symptomatic.

Unfortunately, it is not free to gluatrica. All 12 previously reported patients had a homogeneous phenotype presenting in infancy with debilitating dystonia and choreoathetosis. 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 hipo 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 during putatively threatening episodes such as infectious disease to prevent striatal injury.
