Genes affected

GGNBP1 (HGNC:19427): (gametogenetin binding protein 1 (pseudogene)) This gene is the ortholog of the mouse gametogenetin-binding protein 1 gene. In human, the open reading frame is disrupted by a nonsense mutation after 8-aa; consequently, this gene is currently considered to be a unitary pseudogene in human even though it is functional in other mammals.

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.88).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.76 is higher than 0.05.
