Most cases of<unk>  recessive cerebellar ataxia are early onset, usually around the age of 20. People with this<unk>  of ataxia share many characteristic symptoms including: * frequent falls due to poor balance * imprecise hand coordination * postural or kinetic tremor of extremities or trunk * dysarthria * dysphasia * vertigo * diplopia * lower extremity tendon reflexes * dysmetria * minor abnormalities in ocular saccades * attention defects * impaired verbal working memory and visuospatial skills * Normal life expectancy<unk>  recessive ataxias are generally associated with a loss of proprioception and vibration sense. Arreflexia is more common in<unk>  recessive ataxia than<unk>  dominant ataxias. Also, they tend to have more involvement outside of the nervous system. Mutations in subunit of the mitochondrial DNA polymerase (POLG) have been found to be a potential cause of<unk>  recessive cerebellar ataxia.
