vision/eye

abnormal retina pigment epithelium morphology ( J:196540 )

♀ • retinal pigment epithelium (RPE) cells exhibit atrophy, hypertrophy and large vacuoles with cells extruded into the photoreceptor layer

homeostasis/metabolism

abnormal iron level ( J:196540 )

♀ • increased iron accumulation in the retinal pigment epithelium at 3 months of age
