Overview

Spinocerebellar ataxia 5 (SCA5) is one of the many spinocerebellar ataxias, which are inherited conditions that cause degeneration of the spinal cord and cerebellum. SCA5 almost exclusively affects the cerebellum. It is considered to be a mild form that progresses slowly. The age of onset is usually between the ages of 20 and 30, but a wide range in age of onset has been reported.[1] Signs and symptoms may include loss of coordination of the hands, arms, and legs; impaired balance when walking; and slurred speech (dysarthria).[2] SCA5 is caused by mutations in the SPTBN2 gene and is inherited in an autosomal dominant manner.[3]
