Popis: A 27-year-old man with negative family history and both parents with normal neurological evaluation and motor nerve conduction velocities (MNCVs) showed onset of severe weakness of feet at 4 years of age. Subsequently he developed left equinovarus deformity, thoracic scoliosis, ulnar nerve enlargement, areflexia, distal hypesthesia and slowing of MNCVs for median and ulnar nerves (15-25 m/sec). Molecular genetic studies showed deletion of one nucleotide (G330) (codon 94) in exon 3 of the PMP22 gene associated with frameshift mutation.
