N normal phenotype
nervous system
• at E13.5 and E15.5, neural tissue apoptosis is increased compared to in wild-type mice
• however, brain morphology is otherwise normal
• brain size is reduced as much as 40% compared to in littermate controls

homeostasis/metabolism
• DNA damage in the brain accumulates with age unlike in wild-type mice
• mice fail to repair ionizing radiation-induced DNA damage after 1 week compared to similarly treated wild-type mice that exhibit repair after 24 hours

behavior/neurological
• at 7 to 9 months, mice develop severe hind-limb ataxia or unknown etiology

cellular
• DNA damage in the brain accumulates with age unlike in wild-type mice
• mice fail to repair ionizing radiation-induced DNA damage after 1 week compared to similarly treated wild-type mice that exhibit repair after 24 hours
