In comparison with a recent study of European patients with idiopathic sensory neuropathy and [(AAGGG)exp/(AAGGG)exp] in RFC1 (8), our patients carrying [(AAGGG)exp/(AAGGG)exp] showed significantly higher frequency (Fisher's exact test) of motor weakness/atrophy (p = 0.022), dysautonomia (p = 0.036), and dysarthria/dysphagia (p = 0.039) (Table 2; gray background). This evidence concerns the gene RFC1 and Sensory neuropathy.
