The NM_058216.3(RAD51C):c.446G>T (p.Gly149Val) variant causes a missense change involving the alteration of a 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 0.000000684 (AC=1) in the gnomAD database across 1,461,878 control chromosomes (no homozygotes observed). The grpmax filtering allele frequency (95% CI) is 0.000000899. In-silico predictor (REVEL) classifies this variant as likely damaging/oncogenic. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. The affected nucleotide is highly conserved across species (PhyloP 100-way vertebrate score: 8.84). 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.G149E: Uncertain_significance (ClinVar VariationId 538761, 2 stars); p.G149= (synonymous): Benign (ClinVar VariationId 3903704, 1 star); p.G149= (synonymous): Likely_benign (ClinVar VariationId 1740875, 2 stars)

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 3 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 = 0.000001, AC = 1 — absent/extremely rare (O3 moderate [+2])
	O6Computational evidence supports deleterious effect		Computational evidence supports a deleterious/oncogenic effect; Missense variant — primary computational scorer supports an oncogenic/deleterious effect
