Genes affected

NFE2L3 (HGNC:7783): (NFE2 like bZIP transcription factor 3) This gene encodes a member of the cap 'n' collar basic-region leucine zipper family of transcription factors. The encoded protein heterodimerizes with small musculoaponeurotic fibrosarcoma factors to bind antioxidant response elements in target genes. This protein is a membrane bound glycoprotein that is targeted to the endoplasmic reticulum and the nuclear envelope. Pseudogenes of this gene are found on chromosomes 16, 17, and 18.

The c.341A>G (p.H114R) alteration is located in exon 1 (coding exon 1) of the NFE2L3 gene. This alteration results from a A to G substitution at nucleotide position 341, causing the histidine (H) at amino acid position 114 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
