The variant received 3 classification points (ACMG Germline Pathogenicity v2019). PM1_SupportingPM2

The NM_058216.3(RAD51C):c.446G>C (p.Gly149Ala) variant causes a missense change involving the alteration of a conserved nucleotide. The variant is absent from the gnomAD population database at sites with sufficient sequencing coverage. 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 ACMG Germline Pathogenicity v2019

Classification was made for transcript:

Our verdict: Uncertain_significance. The variant received 3 points.

Apply	Criterion Code & Title / Strength	Strength	Rationale / Clinical Context
	PM1Mutational hot spot or critical domain		Missense neighbourhood moderate hotspot (≥2 P/LP within ±8 AA, OR ≥ 2 vs. background) — PM1 supporting; In-domain: 0 pathogenic, 0 benign rare missense variants.; ±8 AA neighbourhood: 5 pathogenic, 9 benign (OR vs. background: 2.9).
	PM2Absent/extremely low in population databases		Absent from gnomAD (AD/XL gene) — PM2; Absent from gnomAD at well-covered site (MOI: AD+AR) (threshold 0.0001) — PM2 moderate.
