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]

Benign, no assertion criteria providedclinical testingDepartment of Pathology and Laboratory Medicine, Sinai Health System-The NFE2L2 p.L177V variant was identified in 1/1362 proband chromosomes (allele frequency: 0.0007) from a healthy population (Bodian_2014_PMID: 24728327). The variant was identified in dbSNP (ID: rs35577826) and ClinVar (classified as benign by Invitae). The variant was identified in control databases in 174 of 280318 chromosomes (0 homozygous) at a frequency of 0.0006207, and was observed at the highest frequency in the African population in 169 of 24140 chromosomes (freq: 0.007001) (Genome Aggregation Database March 6, 2019, v2.1.1). This frequency is greater than expected for the rare, autosomal dominant immunodeficiency, developmental delay, and hypohomocysteinemia condition associated with NFE2L2 variants. The p.L177 residue is not conserved in mammals and computational analyses (MUT Assesor, PolyPhen-2, SIFT, MutationTaster, Revel, FATHMM, MetaLR, DANN) do not suggest a high likelihood of impact to the protein; this information is not predictive enough to rule out pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (Splice AI exome) do not predict an effect on splicing. In summary, based on the above information this variant meets our laboratory's criteria to be classified as benign. -
