Spinocerebellar ataxia (SCA)

Spinocerebellar ataxia (SCA)is a hereditary disease which can be tested with a DNA test. Spinocerebellar Ataxia (SCA) and Late Onset Ataxia (LOA) in dog are progressive hereditary diseases of gait incoordination and loss of balance. These hereditary diseases gradually affect parts of nervous system in cerebellum, which coordinate movement. 

Clinical signs of Spinocerebellar Ataxia (SCA) usually become notable between 2 and 6 months of age and are similar to symptoms of Late Onset Ataxia (LOA). Observed symptoms include uncoordinated walking, problems with movement or, in some cases, complete loss of ability to move. In SCA but not in LOA, dogs have a series of seizures and myokymia. At the later stages of the disease, some dogs must be euthanized. 

The symptoms are very similar to signs shown by dogs affected with Late Onset Ataxia (LOA), so there may be confusion in identification of this  hereditary disease.
