• Allelic Composition: Fkrp^tvrm53/Fkrp^tvrm53
• Genetic Background: C57BL/6J-Fkrp^tvrm53/Pjn

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

cardiovascular system

abnormal retina vasculature morphology ( J:243745 )

• aberrant vascular formations, excess and tortuous retinal vessels, and vascular structures are found in the vitreous where the inner nuclear layer is disrupted

nervous system

abnormal Muller cell morphology ( J:243745 )

• immunohistochemistry for glial fibrillary acidic protein indicates Muller cell activation as early as 1 months of age

muscle

centrally nucleated skeletal muscle fibers ( J:243745 )

• spinal muscles have fewer nuclei in the fiber periphery than are found in controls, indicative of regeneration in degenerating muscle, with an approximately 17-fold increased in the percentage of fibers with central nucleai

dystrophic muscle ( J:243745 )

vision/eye

abnormal retina vasculature morphology ( J:243745 )

• aberrant vascular formations, excess and tortuous retinal vessels, and vascular structures are found in the vitreous where the inner nuclear layer is disrupted

abnormal Muller cell morphology ( J:243745 )

• immunohistochemistry for glial fibrillary acidic protein indicates Muller cell activation as early as 1 months of age

abnormal retina inner nuclear layer morphology ( J:243745 )

thin retina inner nuclear layer ( J:243745 )

• thin as early as 1 month of age

thin retina outer nuclear layer ( J:243745 )

• as early as 1 month of age

vitreal fibroplasia ( J:243745 )

increased a-wave amplitude ( J:243745 )

• under dark-adapted conditions, although similar to wildtype controls at high flash levels, the a-waves are larger than normal at intermediate flash levels with a slower onset of the b-wave

abnormal b-wave amplitude ( J:243745 )

• dark-adapted electroretinograms show an increased b-wave at low flash levels and a decreased b-wave at high flash levels

abnormal cone electrophysiology ( J:243745 )

• light-adapted electroretinograms show a reduced response across all stimulus conditions assessed, but this is less severe than that seen in mutants of Large1 or Egflam
