|
mortality/aging
N |
• more Nxf1Mvb1-CAST/Ei homozygotes are generated from a cross betwen Eya1bor and Nxf1Mvb1-CAST/Ei mice than non-Nxf1Mvb1-CAST/Ei homozygotes
|
behavior/neurological
|
• only mild tremors are observed
|
nervous system
N |
• no abnormalities are detected in the brains stem or spinal cord
|
hearing/vestibular/ear
|
• the auditory brainstem threshold is increased compared to wild-type mice but intermediate between Eya1bor Nxf1Mvb1-C57BL/6J and Eya1bor Nxf1Mvb1-CAST/Ei homozygotes
|
behavior/neurological
|
• mice exhibit less noticeable head bobbing compared to Eya1bor Nxf1Mvb1-C57BL/6J homozygotes
|
|
• mice exhibit less noticeable circling compared to Eya1bor Nxf1Mvb1-C57BL/6J homozygotes
|
hearing/vestibular/ear
|
• the auditory brainstem threshold is increased compared to wild-type mice but less than that of Eya1bor Nxf1Mvb1-C57BL/6J homozygotes
|
nervous system
|
• 6 of 12 mice have a loss of spiral ganglion cells in the apical turn of the cochlea
• 3 of 12 mice have more severe phenotypes
|
renal/urinary system
N |
• mice do not exhibit kidney defects or associated mortality as in Eya1bor homozygotes
|
Ap3d1mh-2J/Ap3d1mh-2J coat color dilution is attenuated in Ap3d1mh-2J/Ap3d1mh-2J Nxf1Mvb1/Nxf1Mvb1 mice
pigmentation
|
• normalization of pigmentation relative to Ap3d1mh-2J single homozygotes
|
behavior/neurological
|
• reduced tremors relative to Ap3d1mh-2J single homozygotes
|
integument
|
• normalization of pigmentation relative to Ap3d1mh-2J single homozygotes
|
behavior/neurological
|
• reduced ataxia relative to Ap3d1mh-2J single homozygotes
|
|
• elimination of the tendency to jump out of open fields in behavior tests displayed by Ap3d1mh-2J single homozygotes
|
behavior/neurological
|
• reduced amplitude of tremors relative to those of Usp14ax-J singlle homozygotes
|
mortality/aging
|
• improved survival compared with Nxf1Mvb1-C57BL/6J/Nxf1Mvb1-CAST/Ei Pitpnavb/Pitpnavb mice
|
behavior/neurological
|
• reduced tremor score compared with Nxf1Mvb1-C57BL/6J/Nxf1Mvb1-CAST/Ei Pitpnavb/Pitpnavb mice
|
mortality/aging
N |
• lethality observed in Pitpnavb mice is suppressed with mice living past 750 days compared to less than 100 days in Pitnavb homozygotes
|
nervous system
|
• fewer neurons with pathologies were observed than in Pitpnavb/Pitpnavb Nxf1Mvb1-CAST/Ei/Nxf1Mvb1-C57BL/6J mice
|
mortality/aging
|
• lethality observed in Pitpnavb mice is suppressed with mice living past 500 days compared to less than 100 days in Pitnavb homozygotes and more than 750 days in Pitnavb Nxf1mvb1-CAST/Ei homozygotes
