| Genetic information | Knock-In of a CAG100 repeat expansion into the Atxn2 gene, to model the neurodegenerative disorder SCA2 (Spinocerebellar Ataxia type 2) |
| Phenotypic information | Homozygous:Survival shortened to ~14 months, progressive weight loss and motor deficits from 30 weeks of age, slightly reduced fertility.Heterozygous:Survival shortened to ~24 months, progressive weight loss and motor deficits after 14 months of age. |
| Breeding history | Generated at Genoway (Lyon, France) in 2016, the mouse line was since maintained under SPF conditions at the ZFE facility of Goethe University Medical Faculty (Frankfurt am Main, Germany), with cryopreservation of heterozygous sperm by Genoway in 2018. |
