Hereditary thermosensitive neuropathy: an autosomal dominant disorder of the peripheral nervous system.
We report the clinical and electrophysiologic characteristics of eight patients (four men and four women) with a hereditary neuropathy with probable thermosensitivity (HTN) of autosomal dominant inheritance. Patients presented reversible episodes of ascending muscle weakness, paresthesiae, and areflexia apparently triggered by an elevation of body temperature over 38.5 degrees C. Mean age at onset was 13 +/- 12 (SD; range 6 to 43). Four patients had suffered up to five attacks. EMG and pathologic findings were compatible with a reversible demyelinating neuropathy such as Guillain-Barré syndrome. We excluded loci causing other hereditary demyelinating neuropathies, such as Charcot-Marie-Tooth disease type I (CMT type I) and hereditary neuropathy with liability to pressure palsies (HNPP), by linkage analysis; thus, HTN is not allelic to either CMT type I or to HNPP.
