Genes affected

NRF1 (HGNC:7996): (nuclear respiratory factor 1) This gene encodes a protein that homodimerizes and functions as a transcription factor which activates the expression of some key metabolic genes regulating cellular growth and nuclear genes required for respiration, heme biosynthesis, and mitochondrial DNA transcription and replication. The protein has also been associated with the regulation of neurite outgrowth. Alternative splicing results in multiple transcript variants. Confusion has occurred in bibliographic databases due to the shared symbol of NRF1 for this gene and for "nuclear factor (erythroid-derived 2)-like 1" which has an official symbol of NFE2L1.

The c.1318G>A (p.G440R) alteration is located in exon 10 (coding exon 9) of the NRF1 gene. This alteration results from a G to A substitution at nucleotide position 1318, causing the glycine (G) at amino acid position 440 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
