MGI Phenotype FUNCTION: This gene encodes galactosylceramidase, the lysosomal hydryolase involved in the catabolism of galactosylceramide. Mutations in this gene result in slow growth, tremors and hind leg weakness, collectively termed as the 'twitcher' phenotype. In humans, deficiency of this gene product causes a lysosomal storage disorder known as Krabbe disease. [provided by RefSeq, Dec 2014]
PHENOTYPE: Homozygotes for spontaneous and targeted mutations exhibit tremors, progressive weakness, wasting, both central and peripheral demyelination, massive accumulation of galactosylceramide, abnormal macrophages, and death by 4 months of age. [provided by MGI curators]
