N normal phenotype
mortality/aging
• most mice die around P20 for unknown reasons

nervous system
N
• mice exhibit normal granule and cone cell proliferation
• at P6 in the dentate gyrus and cortex
• at P6 and 2 months of age, but not P1
• dentate granule cells exhibit aberrant outgrowth of mossy fibers into CA3 compared with wild-type cells
• however, transfection of retina with an adenovirus expressing a short-hairpin RNA targeting Lhx2 rescues dentate gyrus axon phenotype
• mice exhibit a reduction in cone cells compared with wild-type mice
• however, transfection of retina with an adenovirus expressing a short-hairpin RNA targeting Lhx2 rescues cone cell reduction

vision/eye
• mice exhibit a reduction in cone cells compared with wild-type mice
• however, transfection of retina with an adenovirus expressing a short-hairpin RNA targeting Lhx2 rescues cone cell reduction
• reduced amplitude

behavior/neurological
• at 4 and 5 months of age

cellular
• at P6 in the dentate gyrus and cortex
