Genes affected
NFE2L2 (HGNC:7782): (NFE2 like bZIP transcription factor 2) This gene encodes a transcription factor which is a member of a small family of basic leucine zipper (bZIP) proteins. The encoded transcription factor regulates genes which contain antioxidant response elements (ARE) in their promoters; many of these genes encode proteins involved in response to injury and inflammation which includes the production of free radicals. Multiple transcript variants encoding different isoforms have been characterized for this gene. [provided by RefSeq, Sep 2015]

This sequence change replaces glutamine, which is neutral and polar, with lysine, which is basic and polar, at codon 556 of the NFE2L2 protein (p.Gln556Lys). This variant is present in population databases (rs777361176, gnomAD 0.008%). This variant has not been reported in the literature in individuals affected with NFE2L2-related conditions. ClinVar contains an entry for this variant (Variation ID: 1677316). 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 NFE2L2 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. -
