Abstract

Our recent studies of the genetic epidemiology of neuromuscular disorders in Gypsies in Bulgaria have revealed that two private disorders, hereditary motor and sensory neuropathy type Lom and hereditary motor and sensory neuropathy type Russe, account for most cases of Charcot-Marie-Tooth disease in this population. In this study, we examined the clinical and electrophysiologic manifestations of the two disorders in childhood, aiming to identify the distinctive features that allow early differential diagnosis. The study included 13 patients, aged between 2 and 15 years. The childhood clinical manifestations of both neuropathies were similar, although they tended to be more severe in hereditary motor and sensory neuropathy type Lom. The nerve conduction velocities in hereditary motor and sensory neuropathy type Lom were lower than in hereditary motor and sensory neuropathy type Russe. Brainstem auditory evoked potentials were abnormal in hereditary motor and sensory neuropathy type Lom, even at an early age, and normal in hereditary motor and sensory neuropathy type Russe. Although electrophysiologic data provide a more reliable differentiation than clinical data, the definitive diagnosis should rely on genetic testing.
