In contrast with these neuromotor associations, the diseases associated with SCN9-11A gene mutations [71] have dysesthesia (e.g., small fiber neuropathy, erythermalgia M615552) or dysautonomia symptoms (hereditary sensory and autonomic neuropathy M615548) that are associated with unmyelinated (autonomic) neurons. This evidence concerns the gene CLPB and neuropathy, small fiber.
