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. The gene discussed is CLPB; the disease is autonomic neuropathy.
