Genes affected

EGR2 (HGNC:3239): (early growth response 2) The protein encoded by this gene is a transcription factor with three tandem C2H2-type zinc fingers. Defects in this gene are associated with Charcot-Marie-Tooth disease type 1D (CMT1D), Charcot-Marie-Tooth disease type 4E (CMT4E), and with Dejerine-Sottas syndrome (DSS). Multiple transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Oct 2008]

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 426 of the EGR2 protein (p.Arg426Gln). This variant is present in population databases (rs780825035, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with EGR2-related conditions. ClinVar contains an entry for this variant (Variation ID: 531676). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt EGR2 protein function with a negative predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
