Mouse lines carrying:
Zpld1sprl mutation (1 available); any Zpld1 mutation (26 available)
phenotype observed in females
phenotype observed in males
N normal phenotype
behavior/neurological
• a significant reduction in vestibulo-occular gain is found in homozygotes but not heterozygotes and homozygotes are more severely impaired than are cwh homozygotes
• approximately half of sprl homozygotes circle whereas all mice homozygous for the cwh allele circle and homozygotes for a null allele were not found to circle

hearing/vestibular/ear
N
• normal ABR thresholds and vestibular sensory evoked potentials, normal appearing cochlea and otoconia in both the saccule and utricle, and intact otoconial membranes despite the vestibular dysfunction
• a significant reduction in vestibulo-occular gain is found in homozygotes but not heterozygotes and homozygotes are more severely impaired than are cwh homozygotes
