Hereditary sensory motor neuropathy type V (HAMN V) is very rare disease entity. The authors experienced a patient who had the findings of peroneal muscular atrophy and pyramidal tract feature. A 20 year-old man was admitted to our hospital due to gait disturbance. Scissoring gait and peroneal muscular atrophy were observed. The findings of electrophysiologic studies were compatible with axonal type peripheral neuropathy. The results of other evaluations were compatible with HAMN V. To our knowledge, it is the first report in Korea.
