SCA7

Chr 3AD

ataxin 7

Also known as: ADCAII, OPCA3, SCA7, SGF73

The protein acts as a component of the SAGA transcription coactivator complex and is necessary for microtubule cytoskeleton stabilization. Mutations cause spinocerebellar ataxia 7, a progressive neurodegenerative disorder characterized by cerebellar ataxia and retinal degeneration that distinguishes it from other spinocerebellar ataxias. The condition follows autosomal dominant inheritance with anticipation, where repeat expansions tend to increase in successive generations.
