They showed that ataxin-7 is cleaved by caspase-7 at the Asp sites at position and and that the proteolytic processing of ataxin-7 may contribute to the pathogenesis of SCA7.

Auditory evoked potential studies may also show lack of ataxia espinocerebelosa I and II. In SCA7, anticipation may be so extreme that children with early-onset, severe disease die of disease complications long before the affected parent or grandparent is symptomatic.
