The NM_058216.3(RAD51C):c.135G>A (p.Glu45Glu) variant causes a synonymous 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 allele was found at a cumulative frequency of 0.0000041 (AC=6) in the gnomAD database across 1,461,872 control chromosomes (no homozygotes observed). The grpmax filtering allele frequency (95% CI) is 0.0000147. Note: a gnomAD entry for this variant shows a statistical allele-bias signature, consistent with mosaic/somatic contamination (e.g. age-related clonal hematopoiesis) rather than true inherited population frequency — this frequency should not be read as evidence of a common, benign germline variant. In-silico predictor (BayesDel (noAF)) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. Variant has been reported in ClinVar as Benign/Likely Benign (★★).

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: Likely_benign. The variant received -3 points.

Apply	Criterion Code & Title / Strength	Strength	Rationale / Clinical Context
	O3Absent or very rare in population		Very rare in gnomAD (popmax AF <0.01%) — O3 supporting; GnomAD effective popmax AF = 0.000015 — very rare (O3 supporting [+1])
	B4Synonymous/intronic, no splicing impact		Synonymous/intronic variant with confirmed no splicing impact (B4 strong); Synonymous variant — splicing algorithms confirm no impact on splicing (B4 strong [-4])
