Genes affected

NKAIN3 (HGNC:26829): (sodium/potassium transporting ATPase interacting 3) NKAIN3 is a member of a family of mammalian proteins (see NKAIN1; MIM 612871) with similarity to Drosophila Nkain (Gorokhova et al., 2007 [PubMed 17606467]).[supplied by OMIM, Jun 2009]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.85).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.527 is higher than 0.05.
