In humans, several mutations in a particular calcium channel, the P/Q type, lead to neurological diseases, one of which manifests to ataxia. Ataxia is a disorder where an individual loses coordination or control of muscle movement. SCA6, or spinocerebellar ataxia type 6, is a movement disorder, which results in the loss of a special type of neuron in the cerebellum called Purkinje cells. These neurons process sensory information to coordinate movements. The disease has a late onset and develops in the second period of life. Patients are often wheelchair-bound, and no therapies are available.
