Abstract:
Cerebellar ataxia, neuropathy, vestibular areflexia syndrome (CANVAS) is an autosomal recessive hereditary disorder characterized by cerebellar ataxia, sensory neuropathy and bilateral vestibulopathy. Recently a biallelic intronic AAGGG repeat expansion in the replication factor C1 (RFC1) gene was identified as the cause of this disorder. Clinical studies of genetically-confirmed CANVAS in the past 2 years have significantly expanded the clinical phenotype of the disease and the concept of RFC1-related disease was proposed. The clinical manifestations, characteristic auxiliary examination, genetic changes of CANVAS were reviewed and the new diagnostic criteria to improve clinicians′ awareness of the disease was discussed in this paper.
