Genes affected

RAD50 (HGNC:9816): (RAD50 double strand break repair protein) The protein encoded by this gene is highly similar to Saccharomyces cerevisiae Rad50, a protein involved in DNA double-strand break repair. This protein forms a complex with MRE11 and NBS1. The protein complex binds to DNA and displays numerous enzymatic activities that are required for nonhomologous joining of DNA ends. This protein, cooperating with its partners, is important for DNA double-strand break repair, cell cycle checkpoint activation, telomere maintenance, and meiotic recombination. Knockout studies of the mouse homolog suggest this gene is essential for cell growth and viability. Mutations in this gene are the cause of Nijmegen breakage syndrome-like disorder.[provided by RefSeq, Apr 2010]

ACMG classification

Verdict is Benign. Variant got -9 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0084890425).
• BP6: Variant 5-132591315-A-G is Benign according to our data. Variant chr5-132591315-A-G is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 232958.We mark this variant Likely_benign, oryginal submissions are: {Benign=1, Uncertain_significance=1}.
• BS2: High Homozygotes in GnomAdExome4 at 3 AD,AR gene

Hereditary cancer-predisposing syndrome Uncertain:1 Benign:1

Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Jun 27, 2023	The p.D515G variant (also known as c.1544A>G), located in coding exon 10 of the RAD50 gene, results from an A to G substitution at nucleotide position 1544. The aspartic acid at codon 515 is replaced by glycine, an amino acid with similar properties. This variant was reported in 1/19 individuals diagnosed with triple negative breast cancer (Spugnesi L et al. Genes Chromosomes Cancer. 2016 Dec;55:915-924). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
