Gene Affected Unc5c: unc-5 homolog C (C. elegans)
Origin Spontanious mutation from LEW inbred at Osaka Prefecture University in 1992. A congenic strain was produced by backcrosses to F344/NSlc strain at Kyoto University.
Strain characteristics Hereditary cerebellar vermis defect. Mutant rats exhibit hind-leg paralysis from about 14 days old. Gross pathology showes the cerebellar vermis defect, fused cerebellar hemispheres and cyst formation. Ectopic dysplastic cerebellar tissues exist in the cerebello-pontine junctional zones. Mild disarrangement of lamination was also observed in the fused cerebellar hemispheres (Kuwamura 1994).
Breeding Conditions Good breeding performance. Sib mating between homorozygous female and heterozygous male.
