Genes affected

NFE2 (HGNC:7780): (nuclear factor, erythroid 2) Enables several functions, including WW domain binding activity; identical protein binding activity; and protein N-terminus binding activity. Contributes to cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in regulation of transcription by RNA polymerase II. Predicted to act upstream of or within several processes, including labyrinthine layer blood vessel development; negative regulation of bone mineralization; and negative regulation of syncytium formation by plasma membrane fusion. Part of protein-DNA complex. [provided by Alliance of Genome Resources, Apr 2022]

The c.995A>T (p.D332V) alteration is located in exon 3 (coding exon 2) of the NFE2 gene. This alteration results from a A to T substitution at nucleotide position 995, causing the aspartic acid (D) at amino acid position 332 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
