The NM_005732.4(RAD50):c.3770C>T (p.Ser1257Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The gene RAD50 is a tumor suppressor gene (CancerMine: 1 TSG, 1 oncogene, 1 driver citations). The gene RAD50 is a known oncogene (CancerMine: 1 TSG, 1 oncogene, 1 driver citations). The gene RAD50 is a cancer driver gene (CancerMine: 1 TSG, 1 oncogene, 1 driver citations). The variant is absent from the gnomAD population database at sites with sufficient sequencing coverage. In-silico predictor (REVEL) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. Variant has been reported in ClinVar as Uncertain Significance (★). Other variants at the same amino acid position have been reported in ClinVar (not pathogenic): p.S1257A: Conflicting_classifications_of_pathogenicity (ClinVar VariationId 183984); p.S1257P: Uncertain_significance (ClinVar VariationId 954365, 1 star)

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 was made for transcript:

Our verdict: Uncertain_significance. The variant received 1 points.

Apply	Criterion Code & Title / Strength	Strength	Rationale / Clinical Context
	O3Absent or very rare in population		Absent or extremely rare in gnomAD (AC ≤ 2) — O3 moderate; GnomAD: AF = absent, AC = 0 — absent/extremely rare (O3 moderate [+2])
	B3Computational evidence does not support deleterious effect		Computational evidence does not support a deleterious effect; Missense variant — primary computational scorer does not support an oncogenic/deleterious effect; supports B3
