Genes affected

MRNIP (HGNC:30817): (MRN complex interacting protein) Enables chromatin binding activity. Involved in several processes, including mitotic G2 DNA damage checkpoint signaling; regulation of double-strand break repair; and response to ionizing radiation. Located in nucleoplasm. Colocalizes with Mre11 complex. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.9).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.761 is higher than 0.05.
