N normal phenotype
• ionizing radiation fails to induce cell death; irradiation-induced cell death is almost absent in the hippocampal dentate gyrus, cerebellum, and cerebral cortex compared to wild-type
• only occasional dead cells are found in the external granule layer of the cerebellum whereas widespread cell death is observed in wild-type after irradiation
• in the retina no apoptosis is seen in the center of the retina compared to wild-type, but apoptosis occurs in the periphery of the irradiated retina of mutant and wild-type mice
• cell death in the subventricular zone after irradiation is present but reduced compared to wild-type

reproductive system
• mice are sterile

• mice are prone to lymphoma
