Spinocerebellar ataxias comprise a large (and expanding) group of diseases characterized by degeneration of the spinal cord and cerebellum. 

There are well over 25 individual spinocerebellar ataxias referred to sequentially as SCA1, SCA2, ... in order of their discovery and genetic characterization.
