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]

This variant is also known as 7297delCT in the literature according to the BIC nomenclature. This variant is expected to result in an absent or non-functional protein product. This variant has been reported in over ten individuals affected with breast and/or ovarian cancer (PMID: 9667259, 16234499, 18824701, 20104584, 21324516, 21913181, 24504028, 24549055, 24728189), as well as colorectal cancer (PMID: 27978560) and high grade prostate cancer (PMID: 34700141). This variant has been identified in 7/282332 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;provider interpretation	Geisinger Autism and Developmental Medicine Institute, Geisinger Health System	Jun 11, 2017	This 6 year old male with global developmental delays (at-risk for mild intellectual disability), ADHD, disruptive behavior, and mild overgrowth was found to carry a maternally inherited 2 bp deletion in the BRCA2 gene. The c.7069_7070delCT pathogenic variant in the BRCA2 gene, previously reported as 7297delCT using alternate nomenclature, has been published in association with early-onset breast cancer, ovarian cancer, and prostate cancer (Garvin et al., 1997; Zhang et al., 2011; Cunningham et al., 2014; Song et al., 2014; Ellingson et al., 2015; Decker et al., 2016). The deletion causes a frameshift and is predicted to cause loss of normal protein function through either protein truncation or nonsense-mediated mRNA decay. Given that this is an adult-onset condition, the patient is not expected to be affected at this time. The patient's mother has not been formally evaluated in the oncology setting, so her current status is unknown. -

It is listed as pathogenic in ClinVar (Variation ID: 38082) and is observed 7 times in the Genome Aggregation Database (7/276,822 alleles). This variant causes a frameshift by deleting two nucleotides, so it is predicted to result in a truncated protein or mRNA subject to nonsense-mediated decay. Based on available information, the variant is considered to be pathogenic. References: Caux-Moncoutier V et al.

Hereditary breast ovarian cancer syndrome Pathogenic:5

Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jan 11, 2024	This sequence change creates a premature translational stop signal (p.Leu2357Valfs*2) 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 (rs756538291, gnomAD 0.006%). This premature translational stop signal has been observed in individual(s) with breast and ovarian cancer (PMID: 9429140, 21324516, 24504028, 24728189). This variant is also known as 7297delCT. ClinVar contains an entry for this variant (Variation ID: 38082). 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	Apr 24, 2019	The p.Leu2357ValfsX2 variant in BRCA2 has been identified in >30 individuals with BRCA2-associated cancers (Garvin 1997, Spearman 2008, Borg 2010, Caux-Moncoutier 2011, Zhang 2011, Breast Cancer Information Core (BIC) database). This variant has also been identified in 7/12892 European chromosomes by the Genome Aggregation Database (GnomAD, http://gnomad.broadinstitute.org); however, 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 2357 and leads to a premature termination codon 2 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 individuals with HBOC. In addition, this variant was classified as Pathogenic on April 22, 2016 by the ClinGen-approved ENIGMA expert panel (ClinVar SCV000282439.1). In summary, this variant meets criteria to be classified as pathogenic for HBOC in an autosomal dominant manner based upon the predicted impact to the protein.

Pathogenic, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	Aug 07, 2017	Variant summary: The BRCA2 c.7069_7070delCT (p.Leu2357Valfs) 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.7133C>G [p.Ser2378X], c.7180A>T [p.Arg2394X], and c.7360delA [p.Ile2454fs). One in silico tool predicts a damaging outcome for this variant. This variant was found in the large control database ExAC at a frequency of 0.000033 (4/121100 control chromosomes), which does not exceed the estimated maximal expected allele frequency of a pathogenic BRCA2 variant (0.0007503). The variant has been identified in numerous patients in published reports (e.g., Thomassen_Acta Oncol_2008). In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as pathogenic. Taken together, this variant is classified as pathogenic. -

Hereditary cancer-predisposing syndrome Pathogenic:2

Pathogenic, criteria provided, single submitter	clinical testing	Ambry Genetics	Nov 27, 2024	The c.7069_7070delCT (p.L2357Vfs*2) alteration, located in exon 14 (coding exon 13) of the BRCA2 gene, consists of a deletion of 2 nucleotides from position 7069 to 7070, causing a translational frameshift with a predicted alternate stop codon after 2 amino acids. This alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. Based on data from gnomAD, this allele has an overall frequency of 0.003% (7/282332) total alleles studied. The highest observed frequency was 0.005% (7/128928) of European (non-Finnish) alleles. This mutation has been reported in multiple hereditary breast and ovarian cancer (HBOC) cohorts (Garvin, 1997; Thomassen, 2008; Borg, 2010; Zhang, 2011; Litton, 2012; Chong, 2014; Song, 2014; Labidi-Galy, 2018; Heramb, 2018; Bertelsen, 2019). This mutation has also been reported in prostate and pancreatic cancer cohorts (Schwartz, 2019; Boyle, 2020; Moses, 2020). Of note, this alteration is also designated as 7297delCT in published literature. Based on the available evidence, this alteration is classified as pathogenic. -

The BRCA2 c.7069_7070delCT variant is predicted to result in a frameshift and premature protein termination (p.Leu2357Valfs*2). This variant has been reported to be causative for hereditary cancer such as breast, ovarian, or colorectal cancers (reported as 7297delCT in Garvin et al. 1997. PubMed ID: 9429140; eTable 3, Pearlman et al. 2017. PubMed ID: 27978560; Table S3, Labidi-Galy et al. 2018. PubMed ID: 29084914; Heramb et al. 2018. PubMed ID: 29339979). This variant is reported in 0.0054% 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/38082/).

The BRCA2 p.Leu2357ValfsX2 variant was identified in 2 of 2856 proband chromosomes (frequency: 0.001) from individuals or families with Breast and/or Ovarian cancer (Garvin, 1997; Zhang, 2011). The variant was also identified in dbSNP (ID: rs80359636) “With pathogenic allele”, HGMD, LOVD, ClinVar database, the BIC database (31X with Important clinical importance), and UMD (34X as a class 5-causal variant). The variant was classified as a pathogenic variant by the Sharing Clinical Reports Project (SCRP) (submitted within the ClinVar database and derived from Myriad reports). The p.Leu2357ValfsX2 deletion variant is predicted to cause a frameshift, which alters the protein's amino acid sequence beginning at codon 2357 and leads to a premature stop codon 2 codons downstream. 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. -
