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

vision/eye

abnormal eye morphology ( J:196742 )

• Background Sensitivity: The presence of the 129P2/OlaHsd allele of Map1a from the transgene rescues some of the photoreceptor degeneration that occurs in tubby homozygotes on a predominantly C57BL/6J background, with an average of 126 photoreceptor nuclei remaining in the outer nuclear layer in the presence of the transgene but only 76 in the tubby homozygotes lacking this transgene

hearing/vestibular/ear

abnormal hearing physiology ( J:75815 )

• Background Sensitivity: The 129P2/OlaHsd-derived sequence of this transgene rescues much of the hearing loss phenotype of tubby homozygotes on the C57BL/6J background

vision/eye

abnormal eye morphology ( J:196742 )

• The presence of the 129P2/OlaHsd allele of Map1a from the transgene rescues some of the photoreceptor degeneration that occurs in Tulp1 null homozygotes, with an average of 177 photoreceptor nuclei remaining in the outer nuclear layer in the presence of the transgene but only 112 in the tubby homozygotes lacking this transgene

N	• Even at 18 months of age no locomotor defects or Purkinje cell loss was found consistent with transgenic rescue of the homozygous mutant phenotype
