The recorded framework is ClinGen RAD51C VCEP v1.0.0. The criteria and strengths shown below come from the saved assessment; this page does not recalculate the classification.
The applied criteria and their strengths are shown as assessed under the stated framework.
NM_058216.3:c.458G>A is extremely rare in population databases: gnomAD v2.1 allele frequency 7.95e-6 (2/251,462 alleles), gnomAD v4.1 allele frequency 1.86e-6 (3/1,614,194 alleles), both well below the 0.1% PM2 threshold. Zero homozygotes observed. Absent from gnomAD-Canada v1.0.
No benign criterion marked as applied in the recorded assessment.
ClinGen Hereditary Breast, Ovarian and Pancreatic Cancer Expert Panel Specifications to the ACMG/AMP Variant Interpretation Guidelines for RAD51C Version 1.0.0 v1.0.0 lacked a usable explicit final combination framework, so generic ACMG/AMP 2015 final-combination rules were applied as fallback; applied criteria: PM2 supporting; combination = 1 supporting, which maps to VUS.
Evidence summaries and captured source records, where available. Missing entries should not be interpreted as negative findings.
gnomAD v4.1: 3 / 1,614,194 alleles. Recorded AF 1.85851e-06. Recorded homozygote count 0.
This variant is present in gnomAD v2.1 (AF= 7.95349e-06; MAF= 0.00080%, 2/251462 alleles, homozygotes = 0) and has highest observed frequency in the Admixed American population (AF= 2.89084e-05; MAF= 0.00289%, 1/34592 alleles, homozygotes = 0).
Recorded SpliceAI maximum delta score: 0.030. Refer to the recorded PP3/BP4 rationale for interpretation.
7 Uncertain significance · 3 Likely pathogenic.
OncoKB did not identify variant-specific reviewed functional evidence for this variant; gene-level curated context is available for reviewer follow-up. RAD51C, a DNA repair protein, is altered by mutation or deletion in certain breast cancers.
This variant has not previously been reported in somatic cancers (COSMIC).
This variant does not lie in a statistically significant hotspot.

NM_058216.3:c.458G>A (p.Gly153Asp) is a missense variant in RAD51C, a gene associated with autosomal dominant predisposition to breast and ovarian cancer (MONDO:0016248, MONDO:0016419) and autosomal recessive Fanconi anemia (MONDO:0019391).
The ClinGen Hereditary Breast, Ovarian and Pancreatic Cancer Expert Panel specifications for RAD51C v1.0.0 provide no criteria-level modifications (criteria set is empty); generic ACMG/AMP 2015 criteria (PMID:25741868) were applied.
This variant is extremely rare in population databases: gnomAD v2.1 allele frequency 7.95e-6 (2/251,462 alleles), gnomAD v4.1 allele frequency 1.86e-6 (3/1,614,194 alleles), meeting PM2 at supporting strength.
In silico predictions are conflicting: REVEL score 0.635 (damaging-leaning) versus BayesDel score 0.233 (benign-leaning); SpliceAI predicts no splice impact (max delta 0.03). Neither PP3 nor BP4 is met.
ClinVar reports this variant as Uncertain significance by 7 clinical laboratories and Likely pathogenic by 3 laboratories (VariationID 185444); no expert panel consensus exists. PP5 and BP6 are not met.
Functional studies of RAD51C missense variants have been published (PMID:36099300, PMID:37253112, PMID:39299233), including saturation genome editing covering >99.5% of coding SNVs (PMID:39299233). However, NM_058216.3:c.458G>A (p.Gly153Asp) is not explicitly mentioned in available abstracts and full-text files were not available for verification. PS3 and BS3 remain not assessed pending full-text review.
No de novo reports, no segregation data, no case-control enrichment data, and no same-residue pathogenic comparator exist. All remaining assessed criteria (PS1, PS2, PS4, PM5, PM6, PP1, PP4, BS1, BS2, BS4, BP2, BP5) are not met.
With only PM2 (supporting) met and no benign criteria satisfied, this variant is classified as a Variant of Uncertain Significance (VUS) under the ACMG/AMP 2015 framework. Definitive classification requires full-text functional data from PMID:39299233 (saturation genome editing) and/or PMID:37253112 (functional characterization of RAD51C missense VUS).
