We report a novel type of hereditary sensory and autonomic neuropathy (HSAN) with adult onset in a Japanese family. One male and 2 females of 6 siblings were affected. They developed anosmia initially at the ages of 20–50 years, followed by anhidrosis and sensory loss. Skin ulceration was absent. Both superficial and deep sensation were impaired in the most distal parts of all 4 limbs. Orthostatic hypotension was present in all patients. This is a unique subtype of HSAN distinct from the HSAN I–V described by Dyck.

Keywords: ageusia; anhidrosis; anosmia; axonal degeneration; hereditary sensory and autonomic neuropathy; orthostatic hypotension
