Spinocerebellar Ataxia 13, also known as spinocerebellar ataxia type 13, is related to spinocerebellar ataxia, autosomal recessive 13 and autosomal dominant cerebellar ataxia, and has symptoms including abnormal pyramidal signs and gait ataxia. An important gene associated with Spinocerebellar Ataxia 13 is KCNC3 (Potassium Voltage-Gated Channel Subfamily C Member 3), and among its related pathways/superpathways are Transmission across Chemical Synapses and Potassium Channels. Affiliated tissues include spinal cord and cerebellum, and related phenotypes are hyperreflexia and nystagmus
