Genes affected

BABAM1 (HGNC:25008): (BRISC and BRCA1 A complex member 1) Involved in several processes, including mitotic G2 DNA damage checkpoint signaling; positive regulation of DNA repair; and protein K63-linked deubiquitination. Located in cytosol and nuclear body. Part of BRCA1-A complex and BRISC complex. [provided by Alliance of Genome Resources, Apr 2022]

ENSG00000269307 (HGNC:):

USHBP1 (HGNC:24058): (USH1 protein network component harmonin binding protein 1) Enables PDZ domain binding activity. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

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

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-1.01).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.669 is higher than 0.05.
