La ataxia espinocerebelosa tipo 2 (SCA2) es una enfermedad genética con Spinocerebellar ataxia type 2 (SCA2) is an autosomal dominant. Spinocerebellar ataxia type 7 (SCA7), currently the only known form of autosomal characterized by progressive ataxia, motor system abnormalities, dysarthria. Infantile-onset spinocerebellar ataxia (IOSCA) is a hereditary neurological disorder with early and severe involvement of both the peripheral and central nervous.

Other forms of ADCA see this term should also be considered but can be excluded based on the absence of retinal degeneration, which is unique to SCA7. This mutation leads to degeneration in the cells of the retina, cerebellum and brainstem. Intellectual disability, peripheral neuropathy, and retinal abnormalities may also occur.
