The NM_000059.4(BRCA2):c.2524G>C (p.Val842Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The gene BRCA2 is a tumor suppressor gene (CancerMine: 139 TSG, 7 oncogene, 19 driver citations). The gene BRCA2 is a cancer driver gene (CancerMine: 139 TSG, 7 oncogene, 19 driver citations). The variant allele was found at a cumulative frequency of 0.00000559 (AC=9) in the gnomAD database across 1,610,388 control chromosomes (no homozygotes observed). The grpmax filtering allele frequency (95% CI) is 0.00009. In-silico predictor (REVEL) 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 (no review stars). Other variants at the same amino acid position have been reported in ClinVar (not pathogenic): p.V842A: Conflicting_classifications_of_pathogenicity (ClinVar VariationId 1918672); p.V842= (synonymous): Likely_benign (ClinVar VariationId 236841, 3 stars); p.V842= (synonymous): Likely_benign (ClinVar VariationId 185410, 3 stars) The variant has been observed in cBioPortal in 2 samples across 2 studies and 1 cancer type; somatic enrichment level: SUPPORTING_LOW (Observed in a small number of cBioPortal cases.).

Genes affected

BRCA2 (HGNC:1101): (BRCA2 DNA repair associated) The product of this gene in involved in maintenance of genome stability. It is involved in double-strand break repair pathways during mitotic and meiotic homologous recombination and functions in protecting DNA replication forks. The encoded protein contains sites for interactions with PALB2 and EMSY and an N-terminal DNA binding domain. It also contains a RAD51 binding domain with multiple components. It has multiple BRC repeats, an alpha helix domain, oligonucleotide binding folds, and a tower-like domain. It has a nuclear localization signal and a phosphorylation site for cyclin-dependent kinase. The C-terminus of the protein can bind single-stranded and double-stranded DNA. The product of this gene interacts with multiple proteins, including RAD51. It is involved in recruiting RAD51 filaments to DNA double-strand break sites and also in cytoplasmic division. It also acts as a tumor suppressor. Mutations in this gene or decreased expression have been implicated in multiple tumor types, including breast, ovarian, pancreatic, prostate and other cancers.

Classification according to ACGS-UK Somatic Oncogenicity v2025

Specifications for BRCA2 are available in the ClinGen Criteria Specification Registry and recommended for reference when assigning criteria.

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		Very rare in gnomAD (popmax AF <0.01%) — O3 supporting; GnomAD effective popmax AF = 0.000090 — very rare (O3 supporting [+1])
	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
