Globoid cell leukodystrophy (GLD), or Krabbe disease, is a severe disorder resulting from a deficiency of galactocerebrosidase (GALC) activity. GALC is responsible for the lysosomal catabolism of certain galactolipids. Clinically, the symptoms appear between 1 and 3 months of age. Weakness of the limbs and tremors appear first, followed by muscular atrophy and neurological degeneration. Affected dogs may live until 8 or 9 months of age, when the symptoms become so severe that the dog is usually euthanized.
