N normal phenotype
behavior/neurological
ataxia ( J:344350 )
• mild ataxia and tremor begin at 4 weeks of age

nervous system
abnormal Purkinje cell morphology ( J:344350 )
• Purkinje cells have fewer lysosomes and autophagosomes and show accumulating protein inclusions
Purkinje cell degeneration ( J:344350 )
• homozygotes display apoptotic Purkinje cell degeneration beginning at 4 weeks of age, which progresses rostrally to caudally with an average of only 16% of Purkinje cells surviving at 1 year

rectal prolapse ( J:237902 )
• double homozygous mothers on the NOD background often develop rectal prolapse after bearing 1 to 3 litters
