Hereditary cancer-predisposing syndrome Pathogenic:3
Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Jan 10, 2024 | The c.5828delC pathogenic mutation, located in coding exon 10 of the BRCA2 gene, results from a deletion of one nucleotide at position 5828, causing a translational frameshift with a predicted alternate stop codon (p.S1943Lfs*20). This alteration has been reported in multiple cohorts of breast and/or ovarian cancer patients (Palma MD et al. Cancer Res. 2008 Sep;68:7006-14; Finkelman BS et al. J. Clin. Oncol. 2012 Apr;30:1321-8; Carter NJ et al. Gynecol Oncol. 2018 12;151:481-488). This alteration was also identified in a patient with prostate cancer and colon polyps (Susswein LR et al. Genet. Med. 2016 08;18:823-32). Of note, this alteration is also designated as 6056delC 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. - |

This variant has also been observed in 9 families among the CIMBA participants (PMID: 29446198). This variant has been identified in 2/250822 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 | Invitae | Jan 21, 2024 | This sequence change creates a premature translational stop signal (p.Ser1943Leufs*20) 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 (rs80359541, gnomAD 0.0009%). This premature translational stop signal has been observed in individual(s) with breast and/or ovarian cancer (PMID: 18703817, 22430266, 26681312). This variant is also known as 6056delC. ClinVar contains an entry for this variant (Variation ID: 37999). For these reasons, this variant has been classified as Pathogenic. - |
Pathogenic, criteria provided, single submitter | clinical testing | Women's Health and Genetics/Laboratory Corporation of America, LabCorp | Jun 27, 2022 | Variant summary: BRCA2 c.5828delC (p.Ser1943LeufsX20) 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 7.9e-06 in 252170 control chromosomes (gnomAD and Malone_2006). c.5828delC has been reported in the literature in multiple individuals affected with breast, ovarian, and other cancers, many of whom also have a family history of cancer (e.g. Palma_2008, Finkelman_2012, Malone_2006, Wang_2014, Susswein_2015, Carter_2018, Rebbeck_2018, Singhal_2021, BIC database). 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. Nine assessments for this variant have been submitted to ClinVar after 2014 and all classified the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. - |
