N normal phenotype
behavior/neurological
• homozygotes generated on a (C57BL/6J x DBA/2J)F2 background are viable and fertile and display the same moderate circling phenotype as that found in heterozygotes on a pure C57BL/6J background, and no additional outward phenotypes are evident

N normal phenotype
behavior/neurological
• heterozygotes have difficulty orienting in water and when at the surface they swim in circles
• heterozygotes display a moderate circling phenotype indicative of a vestibular defect

hearing/vestibular/ear
N
• despite the vestibular defect no hearing impairment was found by ABR at 1, 2, or 3 months of age
