MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a protein that catalyzes the synthesis of 2-hydroxysphingolipids, a subset of sphingolipids that contain 2-hydroxy fatty acids. Sphingolipids play roles in many cellular processes and their structural diversity arises from modification of the hydrophobic ceramide moiety, such as by 2-hydroxylation of the N-acyl chain, and the existence of many different head groups. Mutations in this gene have been associated with leukodystrophy dysmyelinating with spastic paraparesis with or without dystonia.[provided by RefSeq, Mar 2010]
PHENOTYPE: Homozygotes for a null allele show demyelination, axonal loss, and cerebellar dysfunction. Homozygotes for a different null allele show late onset axon and myelin sheath degeneration, delayed fur emergence, altered sebum composition, sebocyte hyperproliferation, and cyclic alopecia.
