Incidental mutations (data from Mutagenetix )
 
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.
