Teaching NeuroImages: Glutaric aciduria type 1 (glutaryl-CoA dehydrogenase deficiency).
A 14-month-old boy presented with loss of developmental milestones and tonic spasms following a diarrheal illness. He was born to nonconsanguineous parents and had mild motor delays. Examination was remarkable for macrocephaly, axial hypotonia, and asymmetric dystonic posturing of neck, trunk, and extremities. Brain MRI (figure) and elevated glutaryl carnitine on tandem mass spectroscopy were d...
متن کاملInteraction of Glutaric Aciduria Type 1-Related glutaryl-CoA Dehydrogenase with Mitochondrial Matrix Proteins
Glutaric aciduria type 1 (GA1) is an inherited neurometabolic disorder caused by mutations in the GCDH gene encoding glutaryl-CoA dehydrogenase (GCDH), which forms homo- and heteromeric complexes in the mitochondrial matrix. GA1 patients are prone to the development of encephalopathic crises which lead to an irreversible disabling dystonic movement disorder. The clinical and biochemical manifes...
متن کاملSpecific glutaryl-CoA dehydrogenating activity is deficient in cultured fibroblasts from glutaric aciduria patients.
Patients with glutaric aciduria (GA) have greatly increased urinary excretion of glutarate. Their leukocyte and fibroblast sonicates have deficient ability to produce 14CO2 from [1,5-14C]glutaryl-CoA, an enzymatic process with two sequential reaction steps, dehydrogenation and decarboxylation. In normal individuals, it is not known whether these two reaction steps require one or two enzymes, an...

متن کاملMultimodal imaging of striatal degeneration in Amish patients with glutaryl-CoA dehydrogenase deficiency.
Despite early diagnosis, one-third of Amish infants with glutaryl-CoA dehydrogenase deficiency (GA1) develop striatal lesions that leave them permanently disabled. To better understand mechanisms of striatal degeneration, we retrospectively studied imaging results from 25 Amish GA1 patients homozygous for 1296C>T mutations in GCDH. Asymptomatic infants had reduced glucose tracer uptake and incr...
