♀	phenotype observed in females
♂	phenotype observed in males
N	normal phenotype

vision/eye

abnormal ocular fundus morphology ( J:101336 )

• slight speckling at 3.5 weeks of age

abnormal optic disk morphology ( J:101336 )

• begin to discolor at 6 weeks of age

abnormal retina morphology ( J:101336 )

• patches of pigmented cells and whitening of blood vessels can be seen at 6 weeks of age

thin retina outer nuclear layer ( J:101336 )

• at 6 weeks of age only 1-3 cell layers are present in the peripheral retina

increased susceptibility to age-related retinal degeneration ( J:75964 , J:101336 )

• slow onset of degeneration; the visual tracking response persists until several weeks of age in contrast to Pde6b^rd1 homozygous mice (J:75964)

• develops as mice age, with signs becoming detectable by 6 weeks of age (J:101336)

• onset is later than in Pde6b^rd1 (J:101336)

decreased visual acuity ( J:101336 )

• at 3.5 weeks of age, at least 20% of mice respond to a 2 degree grating and 50% respond to a 4 degree grating in a visual tracking drum assay

• at 6 weeks of age mice respond only to an 8 degree grating

• by 10 weeks of age mice fail to respond in a visual tracking drum assay

blindness ( J:101336 )

• effectively blind by 10 weeks of age

nervous system

abnormal optic disk morphology ( J:101336 )

• begin to discolor at 6 weeks of age

vision/eye

abnormal retina morphology ( J:101336 )

• patches of pigmented cells are seen at 3.5 weeks of age

thin retina outer nuclear layer ( J:101336 )

retina degeneration ( J:75964 , J:101336 )

• slow onset of degeneration; the visual tracking response persists until several weeks of age in contrast to Pde6b^rd1 homozygous mice (J:75964)

• patches of pigmented cells are seen at 3.5 weeks of age (J:101336)

decreased visual acuity ( J:101336 )

• at 3.5 weeks of age, no mice respond to a 2 degree grating and 40% respond to a 4 degree grating in a visual tracking drum assay
