MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene belongs to the UDP-glycosyltransferase family. It catalyzes the transfer of galactose to ceramide, a key enzymatic step in the biosynthesis of galactocerebrosides, which are abundant sphingolipids of the myelin membrane of the central and peripheral nervous systems. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Sep 2011]
PHENOTYPE: Mutants fail to make galactolipid galactocerebroside and its sulfated derivative that are normal myelin constituents. Mutants have tremors, ataxia, progressive hindlimb paralysis and vacuole formation in ventral spinal cord due to abnormal myelin sheath. [provided by MGI curators]
