Hereditary breast ovarian cancer syndrome Pathogenic:8Other:1
Pathogenic, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Jan 25, 2024 | This sequence change creates a premature translational stop signal (p.Arg3128*) 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 (rs80359212, gnomAD 0.02%). This premature translational stop signal has been observed in individual(s) with breast cancer, ovarian cancer, and prostate cancer (PMID: 10978364, 11400546, 15168169, 16683254, 16905680, 20736950, 24156927, 24556621, 24728189, 24916970). This variant is also known as 9610C>T. ClinVar contains an entry for this variant (Variation ID: 52826). For these reasons, this variant has been classified as Pathogenic. - |

Pathogenic, criteria provided, single submitter | clinical testing | Pittsburgh Clinical Genomics Laboratory, University of Pittsburgh Medical Center | Oct 04, 2018 | This sequence variant is a single nucleotide substitution (C>T) in exon 25/28 of the BRCA2 gene that changes the arginine at position 3128 to an early termination codon. This is expected to result in nonsense-mediated decay of the resulting transcript and no functional protein from the variant allele. This is a rare variant, and is found at a frequency of 0.00002 in the gnomAD population database (5/277070 alleles, 0 homozygotes). This is a well-characterized, known pathogenic variant which has been reported in breast and ovarian cancer cohorts and families worldwide (PMIDs 29446198, 28294317, 27741520, 28477318, 24916970, 10978364, 15168169). This variant has been identified and classified by the ENIGMA BRCA1 and BRCA2 expert consortium as a pathogenic variant on April 22, 2016. Considering all of the available data, we consider this to be a pathogenic variant. - |

Pathogenic, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Jul 15, 2021 | The p.Arg3128X variant in BRCA2 has been previously reported in >15 individuals with BRCA2-associated cancers (Plaschke 2000 PMID:10978364, Edwards 2010 PMID: 20736950, Leongamornlert 2014 PMID:24556621, Song 2014 PMID: 24728189, Fernandes 2016 PMID:27741520, Gabaldo Barrios 2017 PMID: 28477318, Alvarez 2017 PMID:29088781, Breast Cancer Information Core (BIC) database: https://research.nhgri.nih.gov/bic/, ClinVar Variation ID:52826). It has also been identified in 0.014% (6/41436) African/African American chromosomes by gnomAD (http://gnomad.broadinstitute.org, v3.1). 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 3128, which is predicted to lead to a truncated or absent protein. Heterozygous loss of function of the BRCA2 gene is an established disease mechanism in individuals with HBOC. This variant was classified as pathogenic on Apr 22, 2016 by the ClinGen-approved ENIGMA expert panel (ClinVar SCV000282472.1). In summary, this variant meets criteria to be classified as pathogenic for autosomal dominant HBOC. ACMG/AMP Criteria applied: PS4, PM2_supporting, PVS1. - |

Pathogenic, criteria provided, single submitter | clinical testing | Women's Health and Genetics/Laboratory Corporation of America, LabCorp | Aug 14, 2017 | Variant summary: The BRCA2 c.9382C>T (p.Arg3128X) 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.9403delC [p.Leu3135fsX28], c.9435_9436delGT [p.Ser3147fsX2], and c.9672dupA [p.Tyr3225fsX30]). This variant was found in the large control database ExAC at a frequency of 0.0000165 (2/121360 control chromosomes), which does not exceed the estimated maximal expected allele frequency of a pathogenic BRCA2 variant (0.0007503). The variant has been reported in multiple affected individuals and was shown to segregate with the disease in multiple HBOC families. 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 submitter | clinical testing | Genetic Services Laboratory, University of Chicago | Apr 30, 2020 | DNA sequence analysis of the BRCA2 gene demonstrated a sequence change, c.9382C>T, which results in the creation of a premature stop codon at amino acid position 3128, p.Arg3128*. This pathogenic sequence change is predicted to result in an abnormal transcript, which may be degraded, or may lead to the production of a truncated BRCA2 protein with potentially abnormal function.

Pathogenic, no assertion criteria provided | clinical testing | PreventionGenetics, part of Exact Sciences | Mar 07, 2024 | The BRCA2 c.9382C>T variant is predicted to result in premature protein termination (p.Arg3128*). This variant has been reported in multiple individuals affected with breast, ovarian and prostate cancer (Edwards et al. 2010. PubMed ID: 20736950; Leongamornlert et al. 2014. PubMed ID: 24556621; Natarajan et al. 2016. PubMed ID: 27831900; Sun et al. 2017. PubMed ID: 28724667; Gabaldó Barrios. 2017. PubMed ID: 28477318). This variant is reported in 0.020% of alleles in individuals of African descent in gnomAD. Nonsense variants in BRCA2 are expected to be pathogenic, and this variant has been classified as pathogenic by an expert panel in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/52826). Given the evidence, we interpret c.9382C>T (p.Arg3128*) as pathogenic. - |

Pathogenic, criteria provided, single submitter | clinical testing | Color Diagnostics, LLC DBA Color Health | Dec 11, 2023 | This variant changes 1 nucleotide in exon 25 of the BRCA2 gene, creating a premature translation stop signal. This variant is expected to result in an absent or non-functional protein product. This variant has been reported in individuals affected with breast and/or ovarian cancer (PMID: 10978364, 11400546, 16905680, 17925560, 24728189, 25452441, 28294317, 28477318, 29088781, 29339979, 29907814). This variant has been identified in 6/282750 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. - |
Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Dec 16, 2021 | The p.R3128* pathogenic mutation (also known as c.9382C>T), located in coding exon 24 of the BRCA2 gene, results from a C to T substitution at nucleotide position 9382. This changes the amino acid from an arginine to a stop codon within coding exon 24. This mutation has been observed in both early-onset breast cancer and early-onset prostate cancer cohorts, as well as in multiple families of various ethnicities with Hereditary Breast and Ovarian Cancer syndrome (Plaschke J et al. J. Med. Genet. 2000 Sep;37:E17; Edwards SM et al. Br. J. Cancer. 2010 Sep;103:918-24; Pal T et al. Cancer. 2015 Dec;121:4173-80; Zhong X et al. PLoS ONE. 2016 Jun;11:e0156789; Donenberg T et al. Breast Cancer Res. Treat. 2016 Aug;159:131-8; Fernandes GC et al. Oncotarget. 2016 Dec;7:80465-80481; Alvarez C et al. Oncotarget. 2017 Sep;8:74233-74243). In addition to Portuguese and Brazilian populations, this mutation has been reported to be frequent in HBOC patients of Madeira ancestry (Silva FC et al. BMC Med Genet. 2014 May;15:55; Peixoto A et al. Clin Genet. 2015 Jul; 88(1):41-8; Miguel I. et al. Ecancermedicalscience. 2012 Jul;15:1261). While this mutation was reported in conjunction with another BRCA2 pathogenic mutation, authors do not comment on phase determination in this individual who was diagnosed with breast cancer at age 44 (Dominguez-Valentin M et al. Hered Cancer Clin Pract. 2018 Jan;16:4). Of note, this alteration is also designated as 9610C>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. - |
