With review of the clinical chart and EMG record of 24 cases diagnosed as Hereditary Motor and Sensory Neuropathy in Seoul National University Hospital, we concluded as follow;

1) The sex distribution was predominently in male affection (83.3%) and the mean age at diagnosis was 18.5 years ranging from 4 year of age to 47 year of age.

2) Among the chief complaints, gait disturbance and lower extremity weakness was the most common complaints (8 cases each).

3) Mean motor nerve conduction velocity revealed that peroneal nerve conduction velocity was slowest as 10.42 m/sec, then tibial nerve 16.71 m/sec, median nerve 31.4 m/sec, ulnar nerve 33.0 m/sec in order.

4) Sensory nerve conduction study was normal in 10.3% of superficial peronal nerve.

5) Most distinct needle EMG finding was detected at distal lower extremity muscles.

6) There was no difinite correlation between motor nerve conduction velocity and clinical findings such as atrophy, deformity.

7) The presumptive distribution of typing was that Type I was 19 cases, Type II was 3 cases, Type III was 1 cases, Type IV was 1 case.
