Genes affected

CCDC170 (HGNC:21177): (coiled-coil domain containing 170) The function of this gene and its encoded protein is not known. Several genome-wide association studies have implicated the region around this gene to be involved in breast cancer and bone mineral density, but no link to this specific gene has been found.

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.88).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.852 is higher than 0.05.
