Pax6Sey mutation (9 available); any Pax6 mutation (90 available)
phenotype observed in females
phenotype observed in males
N normal phenotype
mortality/aging
• develop to term but die of breathing problems associated with the lack of a nose

vision/eye

nervous system
• at E10.5 Nkx2.2+ V3 progenitors show dorsal expansion in the thoracic and cervical regions of the spinal cord
• anterior pretectum is reduced but present and the posterior pretectum scarcely exists at E12.5
• diencephalic structures were poor but present
• prethalamus and thalamus were reduced at E12.5
• E17.5 mutants show a greater than 90% reduction in the number of calbindin-positive cells close to the white matter in the spinal cord, indicating that Renshaw cells fail to develop
• no synaptic potentials are evoked by ventral root stimulation, indicating that Renshaw cell inputs to motor neurons are absent

respiratory system
• due to lack of nose
• cause of perinatal death

craniofacial

cellular
• at E10.5 Nkx2.2+ V3 progenitors show dorsal expansion in the thoracic and cervical regions of the spinal cord
