Ultrastructural examination of Rpgrip1tm1Tili/Rpgrip1tm1Tili mouse photoreceptors

vision/eye
• outer segment disks are grossly oversized by P15 and appear disorganized; stacks of disk membranes are frequently arranged parallel to the long axis of the outer segments instead of the normal perpendicular orientation
• near complete loss of photoreceptor cells by 3 months of age
• at 20-30 days of age, cone ERGs show reduced amplitude
• at 20-30 days of age, dark-adapted (rod) ERG analysis shows a greatly reduced maximum amplitude and a reduced sensitivity in mutants

nervous system
• outer segment disks are grossly oversized by P15 and appear disorganized; stacks of disk membranes are frequently arranged parallel to the long axis of the outer segments instead of the normal perpendicular orientation
• near complete loss of photoreceptor cells by 3 months of age
