Genes affected

SQSTM1 (HGNC:11280): (sequestosome 1) This gene encodes a multifunctional protein that binds ubiquitin and regulates activation of the nuclear factor kappa-B (NF-kB) signaling pathway. The protein functions as a scaffolding/adaptor protein in concert with TNF receptor-associated factor 6 to mediate activation of NF-kB in response to upstream signals. Alternatively spliced transcript variants encoding either the same or different isoforms have been identified for this gene. Mutations in this gene result in sporadic and familial Paget disease of bone. [provided by RefSeq, Mar 2009]

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

Our verdict: Likely_benign. The variant received -3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.23466372).
• BP6: Variant 5-179836512-C-A is Benign according to our data. Variant chr5-179836512-C-A is described in ClinVar as Likely_benign. ClinVar VariationId is 475396.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=1.18 with no splicing effect.
