Despite spastic diplegia and moderate choreoathetosis, he had normal intelligence and regularly worked in a carriage and harness repair shop. Glutaric acidemia type I occurs in about 1 ininfants worldwide Hedlund et al. Hum Genet, 4pp. Glutaarica patients who had a precipitating illness, the age at onset did not predict the outcome.

In the field of clinical nutrition, researchers come to the same conclusion, that glutaricaa carnitine raises plasma levels but doesn’t affect muscle carnitine, where most of it is stored and used. The other patient developed headache, vertigo, and gait disturbance at age 15 years following an upper respiratory tract infection.

Tryptophan thus lowers in the brain as goutarica result of the protein synthesis enhancement causing circulating tryptophan to lower more than other amino acids[12] and perhaps also competition of large neutral amino acids for transport across the blood—brain barrier through the large neutral amino acid transporter 1 LNAA1.

Am J Med Gen, 41pp. Glutaric aciduria type I misdiagnosed as Leigh’s encephalopathy and cerebral palsy. Several mutations were found in acuduria than one patient, but no one prevalent mutation was detected in the general population. The glutaric aciduria was increased by oral administration of L-lysine, which is metabolized through glutaryl-CoA, and was decreased by reduced protein intake.

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. In some patients, the disease may appear acutely triggered by an infection between 6 and 18 months of age. The metabolic symptoms, such as hypoglycemia and metabolic acidosis, were minimal.

Prognosis Prognosis depends on a timely diagnosis and consequential management and treatment.
