N normal phenotype
mortality/aging
• 48% of mice do not reach adulthood

reproductive system
• despite no obvious defects in ovary morphology, females are sterile

nervous system
• unlike in wild-type mice, at P21 the external granule layer persists and granular precursor cells are still present
• at P15, arborization of Purkinje cell dendrites is reduced by number and size of dendritic spines

behavior/neurological
• mice display an ataxic bearing and spread their hindlimbs to maintain their posture

growth/size/body
• while surviving mice gain weight they suffer from a permanent and disproportioned dwarfism

homeostasis/metabolism
• mice exhibit a defect in thermogenesis such that the body temperature in some mice drops within a few hours after cold exposure

cardiovascular system
• 224+/-24 beats per minute compared to 393+/-45 beats per minute in wild-type mice
• mice sometime display cardiac arrhythmia

skeleton
• ossification of the long bones is delayed

hematopoietic system
• at P15, spleen weight is decreased (26.9+/-12.2 mg compared to 39.5+/-9.1 mg in wild-type mice)

vision/eye
• eyelid opening was delayed to P25 compared to P15 in wild-type mice

immune system
• at P15, spleen weight is decreased (26.9+/-12.2 mg compared to 39.5+/-9.1 mg in wild-type mice)
