involves: 129P2/OlaHsd * C57BL/6 * FVB/N
Key:
phenotype observed in females
phenotype observed in males
N normal phenotype
mortality/aging
• mutant males die within 24 - 48 hours of birth, with only 1 male surviving to 24 days of age

behavior/neurological
• mutant males lack milk in their stomachs
• mutant males do not suckle well

growth/size/body
• mutants are smaller at birth

nervous system
• the dentate gyrus is replaced by a mass of disorganized cells
• reduced numbers of CA1 and CA3 pyramidal neurons are seen
• the subiculum and hippocampus are reduced in size
• the frontal cortex is reduced in size especially in the caudal-medial cortex and cell density is decreased in the cortex as a result of increased cell death and not a change in proliferation
• cell numbers in the cortical plate are reduced by 20-30%
• cell loss is not seen at E13.5 but is significant at E15.5
