Description

Common founder variant in the Ashkenazi Jewish population (Oddoux 1996); Frameshift variant predicted to result in protein truncation or nonsense mediated decay in a gene for which loss-of-function is a known mechanism of disease; Published functional studies demonstrate a damaging effect: increased sensitivity to MMC, decreased HDR, and increased centrosome amplification compared to wild-type (Wu 2005); Observed in approximately 1% of the Ashkenazi Jewish population (Oddoux 1996); Truncating variants in this gene are considered pathogenic by a well-established clinical consortium and/or database; Also known as 6174delT; This variant is associated with the following publications: (PMID: 20736950, 20887823, 28049106, 28291774, 30620386, 27836010, 23633455, 15695382, 19188187, 22703879, 22009639, 22430266, 23658460, 23341105, 22006311, 21324516, 8673091, 25980754, 26440929, 27425403, 14559878, 26681312, 29321669, 29339979, 29433453, 29368341, 29084914, 27989354, 29907814, 26556299, 10464624, 28767289, 8841192, 29161300, 29439820, 30274973, 30152102, 29506128, 30122538, 30716324, 30186769, 30720243, 29961768, 30702160, 29978187, 30322717, 29937315, 30113427, 30489631, 31263054, 31444830, 32438681, 31512090, 29625052, 26689913, 31447099, 31948886, 34308366, 10739756, 10733239, 34399810, 33077847, 31589614, 32853339, 32341426, 32719484, 32885271, 32338768, 30787465, 30613976, 33087929)

Description

This frameshift variant alters the translational reading frame of the BRCA2 mRNA and causes the premature termination of BRCA2 protein synthesis. The frequency of this variant in the general population, 0.00011 (14/128890 chromosomes, http://gnomad.broadinstitute.org), is uninformative in assessment of its pathogenicity. In the published literature, the variant has been reported as a BRCA2 founder variant in the Ashkenazi Jewish population with a carrier frequency of approximately 1.52% (PMID: 17591843 (2007) and 8841191 (1996)). Based on the available information, this variant is classified as pathogenic.

Description

The BRCA2 c.5946delT; p.Ser1982ArgfsTer22 variant (rs80359550), also published as 6174delT, is reported as a pathogenic founder variant in the Ashkenazi Jewish population (Abeliovich 1997, Couch 1996, Finkelman 2012), and has been associated with hereditary breast and ovarian cancer syndrome. The variant is reported as pathogenic by several sources in the ClinVar database (Variation ID: 9325) and is found in the Ashkenazi Jewish population with an allele frequency of 0.6% (61/10,364 alleles) in the Genome Aggregation Database. This variant causes a frameshift by deleting a single nucleotide, so it is predicted to result in a truncated protein or mRNA subject to nonsense-mediated decay. Based on available information, this variant is considered to be pathogenic. References: Abeliovich D et al. The founder mutations 185delAG and 5382insC in BRCA1 and 6174delT in BRCA2 appear in 60% of ovarian cancer and 30% of early-onset breast cancer patients among Ashkenazi women.

Description

This variant is a deletion of one nucleotide, resulting in a frameshift and the creation of a novel translational stop codon after 22 amino acid residues. The protein product thus produced is truncated and non-functional. Truncating variants in BRCA2 are known to be pathogenic. In the literature, this variant is also known as 6174delT and is a common cause of breast and ovarian cancer in the Ashkenazi Jewish population (PMID: 9042909, 22430266). Moreover, it has been reported in individuals of other ethnicities (PMID: 8758903, 10417300). This variant has been associated with a 43% to 55% risk of breast cancer by age 70, and a 20% to 37% risk of ovarian cancer by age 70 (PMID: 15994883). The mutation database ClinVar contains entries for this variant (Variation ID: 9325).
