Spinocerebellar ataxia type 6 (SCA6) is a rare late-onset autosomal dominant disorder which like other types of SCA is characterized by dysarthria oculomotor disorders [peripheral neuropathy]] and ataxia of gait stance and the limbs due to cerebellar dysfunction. Unlike other types SCA 6 is not fatal. This cerebellar function is permanent and progressive differentiating it from episodic ataxia type 2 (EA2) where said dysfunction is episodic.
