Genes affected
BRCA2 (HGNC:1101): (BRCA2 DNA repair associated) Inherited mutations in BRCA1 and this gene, BRCA2, confer increased lifetime risk of developing breast or ovarian cancer. Both BRCA1 and BRCA2 are involved in maintenance of genome stability, specifically the homologous recombination pathway for double-strand DNA repair. The largest exon in both genes is exon 11, which harbors the most important and frequent mutations in breast cancer patients. The BRCA2 gene was found on chromosome 13q12.3 in human. The BRCA2 protein contains several copies of a 70 aa motif called the BRC motif, and these motifs mediate binding to the RAD51 recombinase which functions in DNA repair. BRCA2 is considered a tumor suppressor gene, as tumors with BRCA2 mutations generally exhibit loss of heterozygosity (LOH) of the wild-type allele. [provided by RefSeq, May 2020]

Pathogenic, no assertion criteria providedclinical testingDepartment of Pathology and Laboratory Medicine, Sinai Health System-The BRCA2 p.Trp1692MetfsX3 variant was identified in 10 of 5448 proband chromosomes (frequency: 0.002) from individuals or families with breast and ovarian cancer (Laarabi 2011, Lubinski 2004, Risch 2001, Suter 2004, Ottini 2009, de Juan 2015, Fernandes 2016, Hasmad 2016). It was also found as a de novo change in a patient who developed early onset breast cancer with no strong family history of the disease (Marshall 2009). The variant was identified in the following databases: dbSNP (ID: rs80359480) as "With Pathogenic allele", ClinVar (18x, pathogenic including review by expert panel ENIGMA), Clinvitae, COGR (3x, pathogenic), LOVD 3.0 (23x, affects function), BIC Database (29x, pathogenic), and ARUP Laboratories (pathogenic). The variant was also identified by our laboratory in 4 individuals with breast, ovarian, and pancreatic cancer. The variant was not found in Cosmic, MutDB, UMD-LSDB, or the Zhejiang University Database. The variant was not identified in the control databases: the 1000 Genomes Project, the NHLBI GO Exome Sequencing Project, the Exome Aggregation Consortium (August 8th 2016), or the Genome Aggregation Database (Feb 27, 2017). The c.5073dupA variant is predicted to cause a frameshift, which alters the protein's amino acid sequence beginning at codon 1692 and leads to a premature stop codon at position 1694. This alteration is then predicted to result in a truncated or absent protein and loss of function. Loss of function variants of the BRCA2 gene are an established mechanism of disease in hereditary breast and ovarian cancer and is the type of variant expected to cause the disorder. In summary, based on the above information this variant meets our laboratory’s criteria to be classified as pathogenic. -
Pathogenic, criteria provided, single submitterclinical testingHuman Genome Sequencing Center Clinical Lab, Baylor College of MedicineOct 12, 2018The c.5073dupA (p.Trp1692Metfs*3) variant in the BRCA2 gene is predicted to introduce a premature translation termination codon. This variant has been reported in multiple patients with breast cancer or ovarian cancer (PMID: 11179017, 14559878, 16683254, 26026974, 26641009). This variant has been seen 29 times in the Breast Cancer Information Core (BIC) dataset and is extremely rare in the general population according to the gnomAD. Therefore, this c.5073dupA (p.Trp1692Metfs*3) variant in the BRCA2 gene is classified as pathogenic. -

This variant has also been reported as a de novo variant in an individual with early onset breast cancer (Marshall 2009), and in an individual with Fanconi anemia who was compound heterozygous with a second pathogenic BRCA2 variant (Offit 2003). The c.5073dupA variant is classified as pathogenic by an expert panel in ClinVar (Variation ID: 37943). This variant causes a frameshift by duplicating a single nucleotide, so it is predicted to result in a truncated protein or mRNA subject to nonsense-mediated decay. Based on available information, this variant is considered to be pathogenic. References: Heramb C et al.

Hereditary breast ovarian cancer syndrome Pathogenic:6Other:1
Pathogenic, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineApr 24, 2019The p.Trp1692MetfsX3 variant in BRCA2 has been identified in >30 individuals of various ethnicities with Fanconi anemia or BRCA2-related cancers (Risch 2001, Offit 2003, Van Der Hout 2006, Laarabi 2011, Breast Cancer Information Core database). It has also been identified in 1/8884 Ashkenazi Jewish chromosomes by the Genome Aggregation Consortium (GnomAD, http://gnomad.broadinstitute.org). This frequency is low enough to be consistent with the frequency of hereditary breast and ovarian cancer (HBOC) in the general population. This variant is predicted to cause a frameshift, which alters the protein’s amino acid sequence beginning at position 1692 and leads to a premature termination codon 3 amino acids downstream. This alteration is then predicted to lead to a truncated or absent protein. Heterozygous loss of function of the BRCA2 gene is an established disease mechanism in HBOC. In addition, this variant was classified as Pathogenic on April 22, 2016 by the ClinGen-approved ENIGMA expert panel (ClinVar SCV000282397.1). In summary, this variant meets our criteria to be classified as pathogenic for HBOC in an autosomal dominant manner. ACMG/AMP criteria applied: PVS1, PS4, PM2. -

Truncations downstream of this position have been classified as pathogenic by our laboratory (e.g., c.5130_5133delTGTA [p.Tyr1710fs). MutationTaster predicts a damaging outcome for this variant. This variant is absent in 119116 control chromosomes (ExAC). The variant has been found in numerous patients/families with breast and/or ovarian cancer, including a confirmed de novo breast cancer case (Marshall_Clin Genet_2009). In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as pathogenic. Taken together, this variant is classified as pathogenic. -
Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJan 28, 2024This sequence change creates a premature translational stop signal (p.Trp1692Metfs*3) 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). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This premature translational stop signal has been observed in individual(s) with breast and/or ovarian cancer, pancreatic cancer, and Fanconi anemia (PMID: 10923033, 11179017, 14559878, 16683254, 22144684, 25479140, 26787237). This variant is also known as 5301insA, 5302insA, and c.5066_5067insA. ClinVar contains an entry for this variant (Variation ID: 37943). For these reasons, this variant has been classified as Pathogenic. -

This variant has been detected in over 20 individuals and families affected with breast, ovarian and fallopian tube cancer (PMID: 11179017, 11938448, 12181777, 14973102, 15131399, 16683254, 18819001, 19052777, 19796187, 21324516, 21465317, 23977390, 24333842, 24728189, 26026974, 26787237, 27741520, 28486781, 32022259, 33471991), an individual affected with pancreatic cancer (PMID: 25479140) and 2 unaffected carriers (PMID: 33471991; Leiden Open Variation Database DB-ID BRCA2_001899). This variant also has been observed with another pathogenic BRCA2 mutation in an individual affected with the recessive disease Fanconi anemia (PMID: 14559878). This variant has been identified in 4/230778 chromosomes in the general population by the Genome Aggregation Database (gnomAD). Loss of BRCA2 function is a known mechanism of disease (clinicalgenome.org). Based on the available evidence, this variant is classified as Pathogenic. -
