The NM_058216.3(RAD51C):c.135G>T (p.Glu45Asp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The gene RAD51C is a tumor suppressor gene (CancerMine: 5 TSG, 2 oncogene, 1 driver citations). The gene RAD51C is a known oncogene (CancerMine: 5 TSG, 2 oncogene, 1 driver citations). The gene RAD51C is a cancer driver gene (CancerMine: 5 TSG, 2 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. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Other variants at the same amino acid position have been reported in ClinVar (not pathogenic): p.E45A: Conflicting_classifications_of_pathogenicity (ClinVar VariationId 492362); p.E45D: Conflicting_classifications_of_pathogenicity (ClinVar VariationId 246164); p.E45= (synonymous): Benign/Likely_benign (ClinVar VariationId 480513, 2 stars); p.E45G: Conflicting_classifications_of_pathogenicity (ClinVar VariationId 140940); p.E45K: Uncertain_significance (ClinVar VariationId 538777, 2 stars); p.E45K: Conflicting_classifications_of_pathogenicity (ClinVar VariationId 1770324) This exact variant is curated in the UniProt human variants database as Uncertain Significance; it is also listed as a COSMIC curated somatic variant.

Genes affected

RAD51C (HGNC:9820): (RAD51 paralog C) This gene is a member of the RAD51 family. RAD51 family members are highly similar to bacterial RecA and Saccharomyces cerevisiae Rad51 and are known to be involved in the homologous recombination and repair of DNA. This protein can interact with other RAD51 paralogs and is reported to be important for Holliday junction resolution. Mutations in this gene are associated with Fanconi anemia-like syndrome. This gene is one of four localized to a region of chromosome 17q23 where amplification occurs frequently in breast tumors. Overexpression of the four genes during amplification has been observed and suggests a possible role in tumor progression. Alternative splicing results in multiple transcript variants.

Classification according to ACGS-UK Somatic Oncogenicity v2025

Classification was made for transcript:

Our verdict: Uncertain_significance. The variant received 0 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])
	B2Does not fit gene mode of action		Activating variant in tumor suppressor gene + same AA change classified germline Benign/Likely Benign — supporting benign evidence (B2, no cancer-type context); Activating variant in tumor suppressor gene + same AA change classified germline Benign/Likely Benign — supporting benign evidence (B2, no cancer-type context)
	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
