What is glutaric acidemia type 1 GA1?
What is glutaric acidemia type 1 GA1?
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.
What causes glutaric aciduria type 1?
Glutaric aciduria type I (GA1) is a rare hereditary metabolic disorder caused by a deficiency of the mitochondrial enzyme glutaryl-CoA dehydrogenase (GCDH). It is in the group of disorders known as cerebral organic acidemias.
What is glutaric acidemia?
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.
How common is glutaric acidemia 1?
Frequency. Glutaric acidemia, type I affects about one 1 of every 40,000 babies born in the United States.
How is glutaric acidemia treated?
Glutaric aciduria type II is treated with a high carbohydrate, low protein and low fat diet. It is recommended that affected individuals eat often to avoid low blood sugar. Dietary supplementation with riboflavin, carnitine & other supplements may be helpful.
How do you test for glutaric acidemia?
In patients with signs and symptoms of glutaric aciduria type I, a specific diagnostic work-up should include quantitative analysis of GA and 3-OH-GA in urine or blood, GCDH gene mutation analysis, and/or enzyme analysis (grade D).
What is glutaric aciduria type 2?
Glutaric aciduria type II (GAII) is one of the conditions termed organic acidemias. Individuals with these conditions have a deficiency or absence of an enzyme that prevents the breakdown of certain chemicals (proteins and fats) in the body, resulting in the accumulation of several organic acids in the blood and urine.
What causes high glutaric acid?
Glutaric aciduria type I is caused by inherited deficiency of glutaryl-CoA dehydrogenase which is involved in the catabolic pathways of L-lysine, L-hydroxylysine and L-tryptophan.
What type of enzyme is acyl CoA Dehydrogenase?
Acyl-CoA dehydrogenases (ACADs) are a class of enzymes that function to catalyze the initial step in each cycle of fatty acid β-oxidation in the mitochondria of cells. Their action results in the introduction of a trans double-bond between C2 (α) and C3 (β) of the acyl-CoA thioester substrate.
Where is acyl CoA dehydrogenase found?
the mitochondria
Acyl-CoA dehydrogenases (ACADs), flavoproteins found in the mitochondria, are involved in β-oxidation of fatty acids.
