This patient is presently less affected compared to previously described Dejerine-Sottas neuropathy (DSN) patients carrying another substitution at codon 359 (Arg359Trp, R359W).
We screened 170 unrelated neuropathy patients without mutations involving the peripheral myelin protein 22 gene (PMP22), the myelin protein zero gene (MPZ), or the gap junction protein beta1 gene (GJB1) and identified two DSN patients with the heterozygous mutation R359W in the alpha-helix domain of the first zinc-finger of EGR2.
A de novo missense mutation (Arg359Trp) in the alpha-helix of the first zinc-finger domain of the EGR2 transcription factor was identified in a patient diagnosed with a clinical phenotype consistent with DSS.
