Overview
Spinocerebellar ataxia 2 is a progressive disorder that causes uncoordinated movement (ataxia), slow eye movement, and sometimes dementia (memory loss). It is caused by a mutation in the ATXN2 gene. It usually affects people in adulthood, but can develop in childhood or adolescence. Each child of a person with spinocerebellar ataxia 2 has a 50% (1 in 2) chance of inheriting the condition.
