Invitae	RCV000044827	SCV000072840	pathogenic	Hereditary breast ovarian cancer syndrome	2024-01-24	criteria provided, single submitter	clinical testing	This sequence change creates a premature translational stop signal (p.Lys2013*) 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 not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with breast cancer, ovarian cancer, fallopian tube cancer, and prostate cancer (PMID: 11802209, 11897832, 17513806, 22006311, 24504028, 24728189, 25111659). This variant is also known as 6265A>T. ClinVar contains an entry for this variant (Variation ID: 38016). For these reasons, this variant has been classified as Pathogenic.
Ambry Genetics	RCV000131111	SCV000186041	pathogenic	Hereditary cancer-predisposing syndrome	2022-03-08	criteria provided, single submitter	clinical testing	The p.K2013* pathogenic mutation (also known as c.6037A>T), located in coding exon 10 of the BRCA2 gene, results from an A to T substitution at nucleotide position 6037. This changes the amino acid from a lysine to a stop codon within coding exon 10. This mutation has been described in multiple breast, ovarian, pancreatic, and prostate cancer patients and families (Meindl A et al. Int. J. Cancer. 2002 Feb;97:472-80; Walsh T et al. Proc. Natl. Acad. Sci. U.S.A. 2011 Nov;108:18032-7; Cunningham JM et al. Sci Rep. 2014 Feb;4:4026; Maier C et al. Prostate. 2014 Oct;74:1444-51; Labidi-Galy SI et al. Clin. Cancer Res. 2018 Jan;24:326-333; Dudley B et al. Cancer. 2018 Apr;124:1691-1700). Of note, this alteration is also designated as 6265A>T in published literature. This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). 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 not been reported in large, multi-ethnic general populations (http://gnomad.broadinstitute.org). In the published literature, the variant has been reported in cases of breast, ovarian, prostate, and fallopian tube cancer, and described as deleterious in the published literature (PMID: 24728189 (2014), 25111659 (2014), 21913181 (2012), 22006311 (2011), 11897832 (2002), 11802209 (2002)). Based on the available information, this variant is classified as pathogenic.

It was absent from large control studies. This nonsens e variant leads to a premature termination codon at position 2013, which is pred icted to lead to a truncated or absent protein. Heterozygous loss of BRCA2 funct ion is an established disease mechanism in hereditary breast and ovarian cancer (HBOC). In summary, this variant meets criteria to be classified as pathogenic f or HBOC in an autosomal dominant manner based upon the predicted impact to the p rotein and presence in affected individuals.

GeneKor MSA	RCV000044827	SCV000693575	pathogenic	Hereditary breast ovarian cancer syndrome	2020-01-01	criteria provided, single submitter	clinical testing	This variant is a single amino acid change from Lysine to a Termination codon at amino acid residue 2013 of the BRCA2 gene. It is expected to result in a truncated, non-functional protein. Truncating variants in the BRCA2 gene are known to be pathogenic. This variant is also known as 6265A>T in the literature and has been reported in patients with breast, ovarian, fallopian tube and prostate cancer (PMID: 11802209, 11897832, 22006311, 25111659). The mutation database ClinVar contains entries for this variant (Variation ID: 38016).

Women's Health and Genetics/Laboratory Corporation of America, LabCorp	RCV000044827	SCV000918981	pathogenic	Hereditary breast ovarian cancer syndrome	2023-07-13	criteria provided, single submitter	clinical testing	Variant summary: BRCA2 c.6037A>T (p.Lys2013X) results in a premature termination codon, predicted to cause an absence of the protein due to nonsense mediated decay, which is a commonly known mechanism for disease. The variant was absent in 253864 control chromosomes. c.6037A>T has been reported in the literature in multiple individuals affected with Hereditary Breast And Ovarian Cancer Syndrome (examples: Meindl_2002, Machado_2007, Song_2014, Litton_2011, Tarabeux_2014, Solano_2016). 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. The following publications have been ascertained in the context of this evaluation (PMID: 11802209, 23961350, 21913181, 23942203, 17513806, 24728189, Solano et al.,(2016) Oncotarget). Multiple submitters have cited clinical-significance assessments for this variant to ClinVar after 2014. All submitters classified the variant as pathogenic, including 1 expert panel (ENIGMA). Based on the evidence outlined above, the variant was classified as pathogenic.
