N normal phenotype
mortality/aging
• mutants die within 30 minutes of birth

nervous system
• at E13.5, apoptosis is increased in the dorsal root ganglia and trigeminal ganglia, but not in the brain
• at E13.5, proliferation is increased in the brain, dorsal root ganglia, and trigeminal ganglia
• at E18.5, mutant brains are visibly larger than controls
• at E18.5, mutant brains weigh 27% more than controls and no signs of hydrocephalus are seen

vision/eye
• at E13.5 and E18.5, ectopic proliferating cells are seen in the interior of the lens and increased apoptosis is seen

behavior/neurological
• seen at E18.5

muscle
• at E18.5 skeletal muscle differentiation is impaired, abnormally large nuclei with inappropriate S-phase activity are present, and myotubes appear diffusely arranged

hematopoietic system
N
• at E13.5 peripheral blood smears contain the normal mix of nucleated and enucleated erythrocytes

liver/biliary system
N
• at E13.5, liver cellularity and level of apoptosis are normal

cellular
• at E13.5, apoptosis is increased in the dorsal root ganglia and trigeminal ganglia, but not in the brain
• at E13.5, proliferation is increased in the brain, dorsal root ganglia, and trigeminal ganglia
