Globoid cell leukodystrophy Terrier type, also known as Krabbe disease, is a neurological disease caused by mutation in the gene for galactocerebrosidase (GALC), enzyme responsible for the lysosomal degradation of specific galactolipids including several important in the production of compact, stable myelin. There is some variability in the onset of clinical signs in affected dogs, ranging from 6 to 20 weeks of age. Symptoms are progressive and include blindness, tremors, incontinence and severe hind leg weakness. MRI findings are abnormal.
