These behavioral and neuropathological traits are common to several SCAs, as it was evidenced by similar results in mouse models of SCA1 (Burright et al., 1995), MJD (Chou et al., 2008; Torashima et al., 2008), or SCA7 (Garden et al., 2002). This evidence concerns the gene ATXN1 and Spinocerebellar ataxia type 3.
