Variant summary

Our verdict is The variant received 13 classification points (ACMG Germline Pathogenicity v2019). PVS1_ModeratePS1_ModeratePS3PM2_SupportingPP5_Strong

The NM_005732.4(RAD50):c.3G>A (p.Met1?) variant causes a start lost change involving the alteration of a conserved nucleotide. The variant disrupts the start codon, preventing normal translation initiation. The variant allele was found at a cumulative frequency of 0.000113 (AC=182) in the gnomAD database across 1,614,054 control chromosomes, including 1 homozygote. The grpmax filtering allele frequency (95% CI) is 0.000128. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. The affected nucleotide is highly conserved across species (PhyloP 100-way vertebrate score: 9.76). Variant has been reported in ClinVar as Pathogenic/Likely Pathogenic (★★). ClinVar reports functional evidence for this variant: "SCV000254904: Disruption of the initiator codon has been observed in individual(s) with breast cancer and/or clinical features of Nijmegen breakage syndrome-like disorder (PMID:26023681, 26094658" and additional evidence is available in ClinVar.

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]

Classification according to ACMG Germline Pathogenicity v2019

Classification was made for transcript

Our verdict: Pathogenic. The variant received 13 points.

PVS1

Start-lost with downstream start: ≥2 pathogenic between starts — moderate ; Start codon lost (exon 1 of 25); downstream rescue start codon present, with 4 pathogenic variants between start codons.

PS1

Different start-lost, 1–2-star ClinVar pathogenic — moderate (PS1); ClinVar contains 1 P/LP entry with the start-lost variant at the same initiation codon (highest review level: 2 stars).

PS3

Well-established functional study supports damaging effect (PS3); SCV000254904: Disruption of the initiator codon has been observed in individual(s) with breast cancer and/or clinical features of Nijmegen breakage syndrome-like disorder (PMID: 26023681, 26094658; internal data).

PM2

Rare in gnomAD for AD/XL gene (popmax AF below threshold) — PM2 Supporting; GnomAD popmax AF = 0.000128 — borderline rare for AD+AR gene (base 0.0001, raised to 0.000198 by highest known P/LP ClinVar AF 0.000198) — PM2 supporting.

PP5

ClinVar 2-star pathogenic — strong (PP5); ClinVar germline classification: Pathogenic/Likely Pathogenic, 2 star(s).
