Pathogenic, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Jan 28, 2024 | This sequence change creates a premature translational stop signal (p.Glu1953*) 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 present in population databases (rs80358814, gnomAD 0.003%). This premature translational stop signal has been observed in individual(s) with breast, ovarian, and prostate cancer (PMID: 9150172, 9792861, 15382066, 16683254, 23318356, 23621881, 28008555). It is commonly reported in individuals of French Canadian ancestry (PMID: 9150172, 9792861, 15382066, 16683254, 23318356, 23621881, 28008555). This variant is also known as 6085G>T. ClinVar contains an entry for this variant (Variation ID: 51952). For these reasons, this variant has been classified as Pathogenic. - |

Pathogenic, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Oct 30, 2020 | The p.Glu1953X variant in BRCA2 has been reported in numerous individuals with BRCA2-associated cancers and segregated with disease in 4 affected individuals from one family (Phelan 1996 PMID: 8673090; Serova-Sinilnikova 1997 PMID: 9150172; Ghadirian 2009 PMID: 19863560; Taherian 2013 PMID: 233108356; Ghadirian 2014 PMID: 23621881; Fernandes 2016 PMID: 27741520; Bannon 2018 PMID: 30274973; Pritzlaff 2017 PMID: 28008555; Breast Cancer Information Core (BIC) database; https://research.nhgri.nih.gov/bic/)). It has also been identified in 0.002% (2/113514) of European chromosomes by 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 nonsense variant leads to a premature termination codon at position 1953, which is predicted to lead to a truncated or absent protein. Loss of function of the BRCA2 gene is an established disease mechanism in autosomal dominant HBOC. Additionally, this variant was classified as pathogenic on Sept. 13, 2016, by the ClinGen-approved ENIGMA expert panel (SCV000300944.2). In summary, this variant meets criteria to be classified as pathogenic for autosomal dominant HBOC. ACMG/AMP Criteria applied: PVS1, PS4, PM2_Supporting, PP1. - |
Pathogenic, criteria provided, single submitter | clinical testing | Women's Health and Genetics/Laboratory Corporation of America, LabCorp | Aug 31, 2020 | Variant summary: BRCA2 c.5857G>T (p.Glu1953X) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. Truncations downstream of this position have been classified as pathogenic by our laboratory. The variant allele was found at a frequency of 8e-06 in 250950 control chromosomes. c.5857G>T has been reported in the literature in multiple individuals affected with Hereditary Breast And Ovarian Cancer Syndrome (example, Frank_1998, Ghadirian_2014, Oros_2004, Serova-Sinilnikova_1997). These data indicate that the variant is very likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Fifteen clinical diagnostic laboratories and one expert panel (ENIGMA) have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All submitters classified the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. - |

BRCA2-related disorder Pathogenic:2
Pathogenic, criteria provided, single submitter | clinical testing | Illumina Laboratory Services, Illumina | Apr 28, 2017 | The BRCA2 c.5857G>T (p.Glu1953Ter) variant is a stop-gained variant that is predicted to result in a premature termination of the protein. The p.Glu1953Ter variant has been reported in at least seven studies in individuals with breast, ovarian or prostate cancer in which it is found in a heterozygous state in at least 44 patients. The variant is a common cause of breast and ovarian cancer in the French Canadian population (Serova-Sinilnikova et al. 1997; Tonin et al. 1998; Oros et al. 2004; van der Hout et al. 2006; Cavallone et al. 2010; Taherian et al. 2014; Ghadirian et al. 2014). Control data are unavailable from these studies for this variant, which is reported at a frequency of 0.00001 in the European (non-Finnish) population of the Exome Aggregation Consortium. This frequency is based on one allele only in a region of good sequence coverage so the variant is presumed to be rare. Although the p.Glu1953Ter variant has not been reported in any cases of Fanconi anemia, it is generally accepted that pathogenic variants in the BRCA2 gene also confer carrier status for Fanconi anemia. Due to the potential impact of stop-gained variants and the supporting evidence, the p.Glu1953Ter variant is classified as pathogenic for BRCA2-related disorders. This variant was observed by ICSL as part of a predisposition screen in an ostensibly healthy population. - |
Pathogenic, no assertion criteria provided | clinical testing | PreventionGenetics, part of Exact Sciences | Jul 30, 2024 | The BRCA2 c.5857G>T variant is predicted to result in premature protein termination (p.Glu1953*). In the literature, this variant is also referred to as c.6085G>T. This variant has been reported in multiple individuals with hereditary breast and ovarian cancer (HBOC) and prostate cancer (Serova-Sinilnikova et al. 1997. PubMed ID: 9150172; Tonin et al. 1998. PubMed ID: 9792861; van der Hout et al. 2006. PubMed ID: 16683254; Taherian et al. 2013. PubMed ID: 23318356; Pritzlaff et al. 2017. PubMed ID: 28008555). Of note, the c.5857G>T (p.Glu1953*) variant is a common cause of HBOC in the French Canadian population (Tonin et al. 1998. PubMed ID: 9792861; Tonin et al. 2001. PubMed ID: 11307153; Oros et al. 2004. PubMed ID: 15382066). This variant is reported in 0.0018% of alleles in individuals of European (Non-Finnish) descent in gnomAD and is interpreted as pathogenic in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/51952/). Nonsense variants in BRCA2 are expected to be pathogenic. This variant is interpreted as pathogenic. - |

Hereditary cancer-predisposing syndrome Pathogenic:2
Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | May 08, 2024 | The p.E1953* pathogenic mutation (also known as c.5857G>T), located in coding exon 10 of the BRCA2 gene, results from a G to T substitution at nucleotide position 5857. This changes the amino acid from a glutamic acid to a stop codon within coding exon 10. This pathogenic mutation is considered a founder mutation in the French Canadian population and has been detected in numerous hereditary breast and/or ovarian cancer families to date (Phelan CM et al. Nat. Genet. 1996 May;13(1):120-2; Serova-Sinilnikova OM et al. Am. J. Hum. Genet. 1997 May;60(5):1236-9; Frank TS et al. J. Clin. Oncol. 1998 Jul;16(7):2417-25; Oros KK et al. Int. J. Cancer. 2004 Nov;112(3):411-9; Cavallone L et al. Fam. Cancer. 2010 Dec;9(4):507-17; Taherian N et al. Nat Rev Urol. 2013 Feb;10(2):116-22; Ghadirian P et al. Clin. Genet. 2014 Jan;85(1):31-5; Fernandes GC et al. Oncotarget. 2016 Dec;7(49):80465-80481). Of note, this alteration is also designated as 6085G>T in published literature. In addition to the clinical data presented in the literature, 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. - |

Pathogenic, no assertion criteria provided | clinical testing | Department of Pathology and Laboratory Medicine, Sinai Health System | - | The BRCA2 p.Glu1953X variant was identified in 28 of 10010 proband chromosomes (frequency: 0.003) from individuals or families with breast, ovarian, and prostate cancer, and it was present in 1 of 3994 control chromosomes (frequency: 0.0002) from healthy individuals (Belanger 2015, Cavallone 2010, Ghadirian 2009, Janavicius 2010, Lubinski 2004, Serova-Sinilnikova 1997, Taherian 2013, Thompson 2016, Tonin 2001, Zhang 2011). The variant was also identified in dbSNP (ID: rs80358814) as “With Pathogenic allele”, ARUP Laboratories BRCA Mutations Database (classified as definitely pathogenic), the ClinVar database (classified as pathogenic 16x including by ENIGMA, Invitae, Ambry Genetics, and GeneDx), the BIC database (32x with clinical importance), UMD (6x with a “causal” classification). The variant was also identified in control databases including the Genome Aggregation Consortium database in 3 of 246032 chromosomes (freq. 0.00001) in the following populations: European in 3 of 111544 chromosomes (freq. 0.00003). The variant was also identified by our laboratory in 5 individuals with breast and pancreatic cancer. The variant described in the literature as a French-Canadian founder mutation (Belanger 2015, Cavallone 2010, Ghadirian 2009, Janavicius 2010, Lubinski 2004, Tonin 2001). The variant has also been described in a Brazilian population (Fernandes 2016). In addition, one case study suggests the variant lead to early-onset and aggressive prostate cancer (Taherian 2013). The p.Glu1953X variant leads to a premature stop codon at position 1953, which is predicted to lead to 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. - |
