Tag-Team Genetics of Spinocerebellar Ataxia 6.

ABSTRACT

In this issue of Neuron, Du et al. (2019) demonstrate that the bicistronic CACNA1A gene encodes a transcription factor α1ACT, mutations in which are associated with SCA6, that controls expression of genes important for cerebellar Purkinje cell development and excitability. Reduction of α1ACT in the adult is well tolerated, suggesting a potential new therapy for SCA6.
