Mouse lines carrying:
Tmiesr mutation (1 available); any Tmie mutation (15 available)
♀ phenotype observed in females
♂ phenotype observed in males
N normal phenotype
behavior/neurological
abnormal behavior ( J:144656 )
• in an open-field test, mice remain in the center longer than wild-type mice
abnormal reflex ( J:116914 )
• abnormal drop reflex; mice do not demonstrate expected dorsoflexion and spread out the front paws when quickly lowered from ~20 cm above a table surface, while controls do exhibit this behavior
impaired balance ( J:144656 )
• mice exhibit impaired balance on a stationary rod compared to wild-type mice
impaired swimming ( J:116914 )
• mice exhibit poor swimming ability; mice can not maneuver in the water and can not remain at the surface
circling ( J:116914 , J:144656 )
• mice exhibit circling with a decreased latency to start circling compared to in cir homozygotes (J:144656)

hearing/vestibular/ear
absent linear vestibular evoked potential ( J:116914 )
• VESPs are absent at the maximum stimulus intensity used
