Cbarcot-Marie-Tooth disease (CMT) comprises a heterogeneous group of hereditary motor and sensory peripheral neuropathies. The autosomal recessive axonal form of CMT (ARCMT2) is ram. Eight patients of a large consanguineous family of Spanish ancestry in Costa Rica were diagnosed with ARCMT2B; previous genetic studies of this family revealed linkage to chromosome 19q13.3. The clinical and electrophysiological features of these patieets are reported. All patients presented with a symmetric motor and sensory neuropathy. which was more pronounced in the lower limbs. Ftuther, distal muscle wasting and impaired deep tendon reflexes were found. Age at onset was between 26 and 42 years, and the disease duration ranged from 2 to 19 yours. Electrophysiological medics revealed a primary tumuli degenerative process. The clinical characteristics of this family differed in several aspects from previously reported families with ARCMT2.
