Find Mice Using the International Mouse Strain Resource (IMSR)
Mouse lines carrying:
Varc mutation (2 available); any Varc mutation (2 available)
phenotype observed in females
phenotype observed in males
N normal phenotype
behavior/neurological
• one heterozgyote was tested and failed to orient in water
• heterozygotes display head tossing and this phenotype is less evident when outcrossed to CAST/EiJ
• Background Sensitivity: heterozygotes have a mild circling phenotype and this is less evident when outcrossed to CAST/EiJ

hearing/vestibular/ear
• all mutants identified with head tossing and circling also have elevated ABR thresholds
• some, but not all, heterozygotes that display head tossing, circling, and elevated ABR thresholds also have otitis media, and this is a secondary phenotype

immune system
• some, but not all, heterozygotes that display head tossing, circling, and elevated ABR thresholds also have otitis media, and this is a secondary phenotype
