title: A novel mutant mouse, joggle, with inherited ataxia.
abstract: While establishing a new mouse strain, we discovered a novel mutant mouse that exhibited ataxia. Mating experiments showed that the mutant phenotype was due to a single autosomal recessive gene, which we have termed joggle (gene symbol: jog). The ataxia becomes apparent around postnatal day 12, when the mice first attempt to walk, and worsens thereafter. The life span of the mutant mouse is comparable to that of the wild-type mouse. After 21 days of age, the cerebellum weights of the jog/jog mice are significantly lower than those of the wild-type mice. These observations indicate that jog/jog mutant mice could be useful models for biomedical research.
