Pathogenic, criteria provided, single submitter | clinical testing | Human Genome Sequencing Center Clinical Lab, Baylor College of Medicine | Aug 13, 2018 | The c.5682C>G (p.Tyr1894*) variant in the BRCA2 gene is located on the exon 11 and is predicted to introduce a premature translation termination codon (p.Tyr1894*), resulting in an absent or disrupted protein product. Loss-of-function variants of BRCA2 are known to be pathogenic (PMID: 8988179, 11897832). This variant has been reported in more than 10 unrelated individuals with breast or ovarian cancer (PMID: 35912179, 31528241, 26852015, 31837001, 33113089, 36119527). This variant is reported in ClinVar as pathogenic (ID: 37989) and reviewed by the expert panel. This variant is rare in the general population according to gnomAD (1/250362). Therefore, the c.5682C>G (p.Tyr1894*) variant of BRCA2 has been classified as pathogenic. - |
Pathogenic, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Oct 14, 2019 | The p.Tyr1894X (c.5682C>G) variant in BRCA2 has been reported in >20 individuals with BRCA2-related cancers (Risch 2001, Edwards 2010, Tea 2014, Alemar 2017, AlDubayan 2018, Dudley 2018, BIC database). Furthermore, another variant at this position resulting in the same amino acid change (c.5681dup, p.Tyr1894X) is classified as pathogenic for hereditary breast and ovarian cancer (HBOC) by our laboratory. The c.5682C>G variant has also been identified in 0.001% (1/113148) of European chromosomes by gnomAD (http://gnomad.broadinstitute.org); however, this frequency is low enough to be consistent with the frequency of HBOC in the general population. This nonsense variant is predicted to lead to a premature termination codon at position 1894, which is predicted to lead to a truncated or absent protein. Loss of function of the BRCA2 gene is an established disease mechanism in HBOC. Finally, the p.Tyr1894X (c.5682C>G) variant was classified as Pathogenic on Apr 22, 2016 by the ClinGen-approved ENIGMA expert panel (Variation ID: 37989). In summary, this variant meets criteria to be classified as pathogenic for autosomal dominant HBOC. ACMG/AMP Criteria applied: PVS1, PM2, PS4, PS1. - |
Pathogenic, criteria provided, single submitter | clinical testing | Women's Health and Genetics/Laboratory Corporation of America, LabCorp | Jun 14, 2016 | Variant summary: The BRCA2 c.5682C>G (p.Tyr1894X) variant results in a premature termination codon, predicted to cause a truncated or absent BRCA2 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 (e.g.c.6644_6647delACTC, c.6682dupG, c.6997_6998delGT, etc.). This variant is absent in 120576 control chromosomes from ExAC. This variant is a recurrent pathogenic mutation found in several HBOC patients/families and in individuals undergoing BRCA1/2 clinical testing. In compound heterozygous with another variant, it has also been reported to cause Fanconi Anemia. Several clinical diagnostic laboratories/reputable databases have classified this variant as pathogenic. Taken together, this variant is classified as a Disease Variant (or Pathogenic). - |

Pathogenic, no assertion criteria provided | clinical testing | Department of Pathology and Laboratory Medicine, Sinai Health System | - | The BRCA2 p.Tyr1894* variant was identified in 18 of 8970 proband chromosomes (frequency: 0.002) from Chinese, Italian, and Czech individuals or families with breast, ovarian and prostate cancers and was not identified in 182 control chromosomes from healthy individuals (Cini 2016, Cao WM, Risch 2001, Edwards 2010, Pohlreich 2005, Borg 2010, Caux-Moncoutier 2009). The variant was also identified in dbSNP (ID: rs41293497) as “With Likely benign, Pathogenic allele”, and in the NHLBI GO Exome Sequencing Project in 1 of 8596 European American alleles (frequency: 0.0001). The variant was identified in ClinVar (classified as pathogenic by ENIGMA, GeneDX, Invitae, Ambry Genetics, and five other submitters). In addition, the variant was identified as pathogenic in the COGR database by Women’s College Hospital, Children’s’ Hospital of Eastern Ontario, Kingston General Hospital – Queen’s University and North York General Hospital. The variant was also identified by our laboratory in three individuals with breast and basal cell carcinomas, in the BIC database (67x as Class 5 with clinical importance), and in the ARUP Laboratories BRCA Mutations Database (as definitely pathogenic). The variant was not identified in COSMIC, the Fanconi Anemia Mutation Database (LOVD), the 1000 Genomes Project, or the Exome Aggregation Consortium database (August 8, 2016). The p.Tyr1894* variant leads to a premature stop codon at position 1894, 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. - |

Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Jan 26, 2022 | The p.Y1894* pathogenic mutation (also known as c.5682C>G), located in coding exon 10 of the BRCA2 gene, results from a C to G substitution at nucleotide position 5682. This changes the amino acid from a tyrosine to a stop codon within coding exon 10. This mutation has been reported in multiple hereditary breast and ovarian cancer (HBOC) cohorts (Risch HA et al. Am. J. Hum. Genet. 2001 Mar;68:700-10; Marroni F et al. Eur J Hum Genet, 2004 Nov;12:899-906; Pohlreich P et al. Breast Cancer Res. 2005 Jul;7:R728-36; Borg A et al.

J Hematol Oncol, 2021 01;14:18; Lerner-Ellis J et al. J Cancer Res Clin Oncol, 2021 Mar;147:871-879), including patients with male breast cancer (Tai YC et al. J Natl Cancer Inst, 2007 Dec;99:1811-4). This mutation has also been reported in individuals with prostate, pancreatic, colorectal and gastric cancers (Edwards SM et al. Br. J. Cancer. 2010 Sep;103:918-24; AlDubayan SH et al. Am J Hum Genet, 2018 03;102:401-414; Dudley B et al. Cancer, 2018 04;124:1691-1700; Wei Y et al. Oncologist, 2020 07;25:e1042-e1050; Zhou J et al. Oncology, 2020 Jun;98:583-588), as well as in members of one Fanconi anemia family (Wagner JE et al. Blood, 2004 Apr;103:3226-9). 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. - |
