Recently, the biallelic expansion of an AAGGG repeat in RFC1 was reported as a cause of cerebellar ataxia with neuropathy and vestibular areflexia syndrome.

Thus, the multisystem disorders caused by this mutation are now considered RFC1-related spectrum disorders. Here, we review the previous reports about RFC1-related spectrum disorders from the aspect of neuropathy.
