MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a protein containing a lipid recognition domain. The encoded protein may function in regulating the transport of cholesterol through the late endosomal/lysosomal system. Mutations in this gene have been associated with Niemann-Pick disease, type C2 and frontal lobe atrophy. [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygotes for a hypomorphic allele exhibit tremors, ataxia, weight loss, changes in lipid homeostasis, NK and T cell physiology, abnormal lysosome morphology, reduced NK cell number, Purkinje cell loss, and premature death. Homozygotes for a gene-trap allele show an identical immune phenotype. [provided by MGI curators]
