Genes affected

ENOX1 (HGNC:25474): (ecto-NOX disulfide-thiol exchanger 1) The protein encoded by this gene is involved in plasma membrane electron transport pathways. The encoded protein has both a hydroquinone (NADH) oxidase activity and a protein disulfide-thiol interchange activity. The two activities cycle with a periodicity of 24 minutes, with one activity being at its peak when the other is at its lowest. [provided by RefSeq, Dec 2016]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.25071448).

The c.1404G>C (p.Q468H) alteration is located in exon 12 (coding exon 9) of the ENOX1 gene. This alteration results from a G to C substitution at nucleotide position 1404, causing the glutamine (Q) at amino acid position 468 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
