Variant summary
Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PVS1PM2PP5_Very_Strong
The NM_000059.4(BRCA2):c.3002C>G(p.Ser1001Ter) variant causes a stop gained change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. S1001S) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Submissions by phenotype
not provided Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | GeneDx | Jun 13, 2022 | Nonsense variant predicted to result in protein truncation or nonsense mediated decay in a gene for which loss of function is a known mechanism of disease; Truncating variants in this gene are considered pathogenic by a well-established clinical consortium and/or database; Not observed at significant frequency in large population cohorts (gnomAD); Observed in an individual with a personal history consistent with pathogenic variants in this gene (Couch 2015); Also known as 3230C>G; This variant is associated with the following publications: (PMID: 25452441) - |
Hereditary cancer-predisposing syndrome Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Aug 17, 2023 | The p.S1001* pathogenic mutation (also known as c.3002C>G), located in coding exon 10 of the BRCA2 gene, results from a C to G substitution at nucleotide position 3002. This changes the amino acid from a serine to a stop codon within coding exon 10. This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). This alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation. - |
Hereditary breast ovarian cancer syndrome Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Sep 11, 2023 | This sequence change creates a premature translational stop signal (p.Ser1001*) in the BRCA2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in BRCA2 are known to be pathogenic (PMID: 20104584). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with breast cancer (PMID: 25452441). ClinVar contains an entry for this variant (Variation ID: 531398). For these reasons, this variant has been classified as Pathogenic. - |
