ACIDURIA GLUTARICA PDF

Back to Health A to Z. Glutaric aciduria type 1 GA1 is a rare but serious inherited condition. It means the body can't process certain amino acids "building blocks" of protein , causing a harmful build-up of substances in the blood and urine. Normally, our bodies break down protein foods like meat and fish into amino acids. Any amino acids that aren't needed are usually broken down and removed from the body.

Pathologic examination reveals striatal degeneration of the caudate and putamen nucleus and biochemical analysis shows glutaryl CoA dehydrogenase deficiency.

Currently, the disease is considered untreatable since there are usually irreversible lesions in the central nervous system at diagnosis. However, treatment can be provided to presymptomatic children and usually to the siblings of patients with this diagnosis.. We present the case of a month-old boy, with macrocephaly and minimal neurologic manifestations at diagnosis, which were attributed to his semivegetarian diet.

A dietary regimen and vitamin supplementation halted and even improved symptomatic progression of the disease. 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..

NCBI Bookshelf. The phenotypic spectrum of untreated glutaric acidemia type 1 GA-1 ranges from the more common form infantile-onset disease to the less common form later-onset disease — i. Of note, the GA-1 phenotype can vary widely between untreated family members with the same genotype , primarily as a function of the age at which the first acute encephalopathic crisis occurred: three months to six years in infantile-onset GA-1 and after age six years in later-onset GA Characteristically these crises result in acute bilateral striatal injury and subsequent complex movement disorders.

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. Worldwide prevalence is estimated at 1 in , births. If undiagnosed, the initial acute encephalopathic crisis occurs between months, typically precipitated by an intercurrent febrile illness, vaccination or a surgical intervention, and characterized by hypotonia, loss of motor skills and convulsions resulting in bilateral striatal injury with severe secondary dystonia and occasionally subdural and retinal hemorrhage.

Glutaric acidemia type I also called glutaric aciduria type I is an inherited disorder in which the body is unable to process certain proteins properly. It is classified as an organic acid disorder, which is a condition that leads to an abnormal buildup of particular acids known as organic acids. Abnormal levels of organic acids in the blood organic acidemia , urine organic aciduria , and tissues can be toxic and can cause serious health problems. People with glutaric acidemia type I have inadequate levels of an enzyme that helps break down the amino acids lysine, hydroxylysine, and tryptophan, which are building blocks of protein. Excessive levels of these amino acids and their intermediate breakdown products can accumulate and cause damage to the brain, particularly the basal ganglia, which are regions that help control movement. Intellectual disability may also occur.
