Much confusion and disagreement exists regarding the classification and characteristics of inherited disorders manifesting neurogenic muscular atrophy. Many authors consider Charcot-Marie-Tooth syndrome (CMTS) and Roussy Levy syndrome (RLS) forme fruste or variants of Friedreich's ataxia (FA). Familial kyphoscoliosis has often been described in FA and RLS but not with CMTS. The purpose of this paper is to present detailed clinical and laboratory findings in a family with three cases of Scheuermann's kyphoscoliosis and CMTS in three generations. In all cases Scheuermann's kyphoscoliosis was associated with pes cavus, markedly diminished vibratory and position sensation in the lower extremities, absent deep tendon reflexes and muscular atrophy, predominantly of the distal muscles. Fine rhythmic tremor of outstretched hands and positive Romberg sign were present in one case only. Serum creating phosphokinase was elevated in two cases. Motor nerve conduction studies revealed impaired function in the median, ulnar, tibial and peroneal nerves. Sensory nerve conduction wal also impaired in median and ulnar nerves. There was evidence of left ventricular hypertrophy in one case only. The nosology and relationship between CMTS, RLS and FA are discussed.
