Genes affected

ZNF280C (HGNC:25955): (zinc finger protein 280C) This gene encodes a member of the zinc finger domain-containing protein family. This family member contains multiple Cys2-His2(C2H2)-type zinc finger domains, the most common type of zinc finger domain that self-folds to form a beta-beta-alpha structure that binds a zinc ion.

ACMG classification

Verdict is Benign. Variant got -13 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.56).
• BP7: Synonymous conserved (PhyloP=1.39 with no splicing effect.
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.674 is higher than 0.05.
