The motor impairment observed in Elovl5−/− mice is reminiscent of the initial stages of ataxia, especially in slowly progressing forms observed in spino-cerebellar ataxia (SCA) patients, in which instability can be revealed by tandem gait while regular walking is not affected (Bodranghien et al., 2016). This evidence concerns the gene ELOVL5 and Ataxia.
