Phenotypes Associated with This Genotype

Genotype
MGI:3028000

• Allelic Composition: Pde6b^atrd1/Pde6b^atrd1
• Genetic Background: involves: BALB/cAnN * C3H/HeN

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

vision/eye

abnormal optic disk morphology ( J:101336 )

• pale by 10 weeks of age

thin retina outer nuclear layer ( J:101336 )

• slightly thinner at 3.5 weeks of age followed by rapid progressive thinning over the next 3 weeks

• at 6 weeks of age, 3-4 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, 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 90% respond to a 4 degree grating in a visual tracking drum assay

• at 6 weeks of age mice respond well to a 4 or 8 degree grating in a visual tracking drum assay

• 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 )

• pale by 10 weeks of age
