vision/eye
abnormal photoreceptor inner segment morphology ( J:160802 )
• at 6 months, mice exhibit a trend towards reduced inner segment thickness compared with wild-type mice
abnormal photoreceptor outer segment morphology ( J:160802 )
• at 6 months, mice exhibit a trend towards reduced outer segment thickness compared with wild-type mice
thin retina outer nuclear layer ( J:160802 )
• a trend at 6 months of age
abnormal cone electrophysiology ( J:160802 )
• at 9 months of age, photopic b-waves are marginally reduced unlike in wild-type mice
abnormal rod electrophysiology ( J:160802 )
• from the age of 3 months onward, mice exhibit a slightly progressive loss of scotopic a-wave amplitude unlike wild-type mice
• as mice age, scotopic b-waves are more stable than in wild-type mice

nervous system
abnormal photoreceptor inner segment morphology ( J:160802 )
• at 6 months, mice exhibit a trend towards reduced inner segment thickness compared with wild-type mice
abnormal photoreceptor outer segment morphology ( J:160802 )
• at 6 months, mice exhibit a trend towards reduced outer segment thickness compared with wild-type mice
