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]

(HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.3164429).

The c.1096G>A (p.G366R) alteration is located in exon 3 (coding exon 2) of the NFE2 gene. This alteration results from a G to A substitution at nucleotide position 1096, causing the glycine (G) at amino acid position 366 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
