vision/eye
• beginning as early as 12 weeks of age,15% of mice exhibit neovascularization of the choroid unlike in wild-type mice
• choroidal neovascular vessels that penetrate Bruch membrane and enter the outer retinal layers are surrounded by hyperplastic retinal pigmented epithelium cells or atrophic retinal pigmented epithelium areas
• microglial infiltrates are observed in retinal lesions
• severity increases with age
• unlike in wild-type mice, vacuolation of the retinal pigmented epithelium (RPE) is observed
• mice exhibit a reduction in melanosomes and an increase in lipofuscin in the RPE unlike in wild-type mice
• unlike in wild-type mice, local hypopigmentation of the retina is observed
• in some areas with severity increasing with age
• by 6 to 9 weeks, mice exhibit drusen-like lesions with heterogeneous, round or domed-shaped, soft-bordered yellowish deposits within the subretina not observed in wild-type mice
• retinal depositions enlarge or flatten and become confluent with age
• beginning at 8 weeks of age, mice exhibit focal thickening in the Bruch membrane compared to wild-type mice

reproductive system
• average litter size is half of wild-type

nervous system
• severity increases with age

pigmentation
• 20% of mice exhibit patchy skin depigmentation on the face and upper extremities
• unlike in wild-type mice, vacuolation of the retinal pigmented epithelium (RPE) is observed
• mice exhibit a reduction in melanosomes and an increase in lipofuscin in the RPE unlike in wild-type mice
• unlike in wild-type mice, local hypopigmentation of the retina is observed
