N normal phenotype
vision/eye
• fundus examination shows discrete white dots by 8 months of age, but not at 4 months of age
• after 2 months of age S-opsin and M-opsin expressing cone cells decrease in number such that at 14 months of age the counts for S-opsin are diminshed to 54% of control and for M-opsin almost indetectable
• the outer plexiform layer appears to form normally but shows diminished thickness by 14 days of age and is nearly absent by 2 months of age
• scotopic ERG responses at 2 months of age show an a-wave about half the normal amplitude, and this amplitude decreases with age with only 27% of control amplitude remaining at 14 months of age
• by one month of age the b-wave is severely diminished but not absent and there are small oscillatory potentials on the flat b-wave, and from 2 months of age on there is little to no waveform resonse in photopic ERGs
• neither green nor UV light ERGs elicited any response after 2 months of age

nervous system
• after 2 months of age S-opsin and M-opsin expressing cone cells decrease in number such that at 14 months of age the counts for S-opsin are diminshed to 54% of control and for M-opsin almost indetectable
