[Globoid cell leukodystrophy].
A 29 year old male with onset of globoid cell leukodystrophy at age 14 is described. This is the first case of enzymatically confirmed globoid cell leukodystrophy with onset of symptoms after the age of ten. This patient is unique because of the late onset and slow progression and extends the clinical spectrum of globoid cell leukodystrophy. Globoid cell leukodystrophy is caused by the deficien...
متن کاملDiagnosis of metachromatic leukodystrophy, Krabbe disease, and Farber disease after uptake of fatty acid-labeled cerebroside sulfate into cultured skin fibroblasts.
[(14)C]Stearic acid-labeled cerebroside sulfate (CS) was presented to cultured skin fibroblasts in the media. After endocytosis into control cells 86% was readily metabolized to galactosylceramide, ceramide, and stearic acid, which was reutilized in the synthesis of the major lipids found in cultured fibroblasts. Uptake and metabolism of the [(14)C]CS into cells from typical and atypical patien...
متن کاملGloboid cell leukodystrophy in cairn and West Highland white terriers.
Krabbe disease or globoid cell leukodystrophy (GLD) is an autosomal recessive disorder resulting from the defective lysosomal hydrolysis of specific galactolipids found primarily in myelin. This leads to severe neurological symptoms including seizures, hypotonia, blindness, and death, usually before 2 years of age in human patients. In addition to human patients, several animals, including dog,...
متن کاملMR of childhood metachromatic leukodystrophy.
PURPOSE To investigate the MR findings of childhood metachromatic leukodystrophy (MLD). METHODS Nine MR imaging studies in seven children (five girls and two boys, 10 to 32 months old) with MLD were evaluated retrospectively for the extent and progression of white matter abnormalities and the presence of contrast enhancement. RESULTS All seven cases showed symmetric, confluent high signal i...
متن کاملHematopoietic stem-cell transplantation in globoid-cell leukodystrophy.
BACKGROUND Globoid-cell leukodystrophy is caused by a deficiency of galactocerebrosidase, which results in progressive central nervous system deterioration. We investigated whether allogeneic hematopoietic stem-cell transplantation can provide a source of leukocyte galactocerebrosidase and thereby prevent the decline of central nervous system function in patients with the disease. METHODS Fiv...
