Myoclonic Epilepsy Myopathy Sensory Ataxia, also known as spinocerebellar ataxia with epilepsy, is related to sensory ataxic neuropathy, dysarthria, and ophthalmoparesis and autosomal dominant cerebellar ataxia. An important gene associated with Myoclonic Epilepsy Myopathy Sensory Ataxia is POLG (DNA Polymerase Gamma, Catalytic Subunit). Affiliated tissues include cerebellum and brain, and related phenotypes are ptosis and depression
