Description

In 2 families from Montreal with breast-ovarian cancer (BROVCA2; 612555), Wooster et al. (1995) found a T deletion and an AAAC deletion (600185.0006), respectively, in the BRCA2 gene. Both of these families included a male breast cancer case; previous analyses had indicated that the large majority of such families have BRCA2 mutations (Stratton et al., 1994).

Description

The BRCA2 p.Ser1982Argfs*22 variant was identified in 33 of 11966 proband chromosomes (frequency: 0.003) from individuals or families with breast, ovarian and pancreatic cancer (Agalliu 2009, Borg 2010, Couch 2014, Edwards 2010, Zhang 2011). The variant was also identified in dbSNP (ID: rs80359550) as â€šÃ„ÃºWith Pathogenic alleleâ€šÃ„Ã¹, ClinVar (classified as pathogenic by 34 submitters including Invitae, GeneDx, Counsyl, ARUP and Ambry Genetics), COGR (3 entries classified as pathogenic), COSMIC (1x confirmed somatic in adenocarcinoma of the pancreas), LOVD 3.0 (110 entries classified as affects function), UMD-LSDB (75 entries classified as causal), BIC Database (1090 entries classified as pathogenic), ARUP Laboratories (classified as definitely pathogenic), and the Zhejiang Colon Cancer Database (classified as pathogenic). The variant was not identified in the MutDB database. The variant was also identified by our laboratory in multiple individuals with breast, ovarian or pancreatic cancer. The variant was identified in control databases in 72 of 276978 chromosomes at a frequency of 0.0003 (Genome Aggregation Database Feb 27, 2017). It was observed in the following populations: Ashkenazi Jewish in 59 of 10150 chromosomes (freq: 0.006), Other in 3 of 6460 chromosomes (freq: 0.0005), European (Non-Finnish) in 10 of 126512 chromosomes (freq: 0.00008); it was not observed in the African, East Asian, European (Finnish), Latino, or South Asian populations. The c.5946delT variant is predicted to cause a frameshift, which alters the protein's amino acid sequence beginning at codon 1982 and leads to a premature stop codon 22 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. The truncating BRCA2 6174delT Ashkenazi Jewish founder mutation is associated with a breast cancer risk of 70% by age 70 and identified in the vast majority of Ashkenazi Jewish families with a history of breast and ovarian cancer (Pohlreich 2005, Wu 2005). In addition, a functional study using bacterial artificial chromosomes concluded that this mutation could not rescue lethality in BRCA2-deficient mouse embryonic stem cells, supporting its classification as deleterious (Kuznetsov 2008). In summary, based on the above information, this variant meets our laboratoryâ€šÃ„Ã´s criteria to be classified as pathogenic. Assessment Date: 2018/03/07.

Description

The c.5946del (p.Ser1982Argfs*22) variant has been detected in a multiple patients with breast and ovarian cancer [reported as c.6174del in PMID 8673091, 23633455, 22006311, 21324516, 22430266]. The variant was also detected in patients with prostate cancer [PMID 19188187, 20736950] and pancreatic ductal adenocarcinoma [PMID 23658460]. This variant is associated with a cancer risk of 50-43% and 18-20% risk for breast and ovarian cancer respectively by age 70 [PMID 9145676,15994883]. In vitro assays showed that this variant leads to a loss of function of the protein [PMID 15695382]. This variant has been reported in 32 non-Finnish Europeans from the ExAC database (http://exac.broadinstitute.org/variant/13-32914437-GT-G). This c.5946del (p.Ser1982Argfs*22) variant occurs at high frequency in the Ashkenazi Jewish population and is considered a founder mutation in this population. This variant is thus classified as pathogenic.[leduc, 2017-03-07]

Description

This variant (rs28897738) has been reported in the literature in association with a variety of BRCA2-related cancer conditions that are inherited in a dominant or recessive manner. It is known as a founder mutation in the Ashkenazi Jewish population and has also been observed in individuals of non-Ashkenazi Jewish descent. It is rare (<0.1%) in a large population dataset (gnomAD: 78/282088 total alleles; 0.0277%; no homozygotes) and has been reported in ClinVar(Variation ID 9325). This frameshift variant results in a premature stop codon in exon 11, likely leading to nonsense-mediated decay and lack of protein production and has supporting functional evidence. We consider this variant to be pathogenic.

Description

The c.5946del, p.Ser1982ArgfsTer22 missense variant identified in BRCA2, also known as c.6174delT, results in a frameshift and premature termination of the protein. The p.Ser1982ArgfsTer22 variant is a founder variant in the BRCA2 gene that is prevalent in the Ashkenazi Jewish and Icelandic populations, and has been previously reported as a heterozygous change in multiple individuals with a personal or family history of breast and/or ovarian cancer, among other types of cancer (PMID: 20301425, 29084914, 29433453, 29321669, 28767289). Based on the available evidence, the c.5946delT, p.Ser1982ArgfsTer22 variant is classified as pathogenic.

Description

The c.5946del variant in BRCA2 is a deletion of a single nucleotide, predicted to encode a frameshift with consequent premature termination of the protein at codon 22 of the frameshift, or amino acid 2003 (p.Ser1982ArgfsTer22). This deletion variant was not observed in gnomAD v2.1 (exomes only, non-cancer subset) or gnomAD v3.1 (non-cancer subset), but PM2_Supporting was not applied since recall is suboptimal for this type of variant (PM2_Supporting not met). Frameshift variant predicted to cause a premature stop codon in biologically-relevant-exon 11 leading to nonsense mediated decay (PVS1 met). The ENIGMA BRCA1/2 VCEP considered multiple lines of functional and clinical evidence to define exon-specific weights for PTC in BRCA2, and results indicate that strong evidence towards pathogenicity may be applied for a PTC variant in BRCA2 exon 11 (PM5_Strong (PTC)). This variant has been detected in 6 individuals with phenotype consistent with BRCA2-Fanconi Anemia (FA). At least two clinical features of FA (physical features, pathology findings and cancer diagnosis <=5yr) and confirmed chromosome breakage, are seen in these individuals. 6 were compound heterozygous for the variant and a pathogenic or likely pathogenic variant, and confirmed to be in trans. Total points equated to 8 (PM3_Strong met; PMIDs: 14559878, 15516848, 16825431, 19530235). In summary, this variant meets the criteria to be classified as a Pathogenic variant for BRCA2-related cancer predisposition based on the ACMG/AMP criteria applied as specified by the ENIGMA BRCA1/2 VCEP (PVS1, PM5_Strong (PTC), PM3_Strong).
