Valentijn et al. (1995) identified a de novo mutation in the PMP22 gene of a patient with Dejerine-Sottas neuropathy (DSS; 145900). Single-strand conformation analysis of PCR-amplified DNA fragments showed an additional fragment for exon 1 in the patient, which was absent in the unaffected parents. Sequence analysis showed a de novo C-to-A transversion at nucleotide 85 that resulted in an amino acid substitution his12-to-gln (H12Q) in the first transmembrane domain of PMP22. The patient had been described as case 13 by Ouvrier et al. (1987). At 4 years of age, the child's height and weight were below the 3rd centile. There was generalized weakness of mild to moderate severity. All tendon reflexes were absent, except the triceps. Peripheral nerves were clinically enlarged. There was moderate truncal ataxia. Sensation was normal, except for mild loss of vibration sensation and diminished 2-point discrimination on the feet. Sensory action potentials could not be recorded from the right median or sural nerves. Motor nerve conduction velocity in the median nerve was 7 m/sec. Sural nerve biopsy at 2 years of age had shown reduced density of myelinated fibers, and all fibers were thinly myelinated and frequently surrounded by onion bulbs.
