Hereditary neuropathy with liability to pressure palsies (HNPP) phenotypes are heterogeneous. We report the case of a 52-year-old woman without medical history, who complained of bilateral hand weakness suggestive first of a motor neuron disorder. The presence of a diffuse predominant distal demyelinating neuropathy suggested a deletion of PMP-22 gene, which was confirmed by genetic analysis. This case report underlines a novel phenotype related to the deletion of PMP-22 gene.
