Genes affected

NFE2L1 (HGNC:7781): (NFE2 like bZIP transcription factor 1) This gene encodes a protein that is involved in globin gene expression in erythrocytes. Confusion has occurred in bibliographic databases due to the shared symbol of NRF1 for this gene, NFE2L1, and for "nuclear respiratory factor 1" which has an official symbol of NRF1.

Collection Method: clinical testing

The c.241C>T (p.R81W) alteration is located in exon 2 (coding exon 1) of the NFE2L1 gene. This alteration results from a C to T substitution at nucleotide position 241, causing the arginine (R) at amino acid position 81 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
