Adult onset neurodegenerative disorder
Gene: POLG
SANDO is an autosomal recessive systemic disorder characterized mainly by adult onset of sensory ataxic neuropathy, dysarthria, and ophthalmoparesis . Spinocerebellar ataxia with epilepsy (SCAE) is a similar disorder with a higher frequency of migraine headaches and seizures.
