The BRCA2 c.6405_6409delCTTAA variant (rs80359584) is reported in the medical literature in individuals with breast cancer or hereditary breast and ovarian cancer (Alemar 2016, Momozawa 2018, Wen 2018, Whitworth 2018). The variant is described as pathogenic by several sources in the ClinVar database (Variation ID: 38043) and is described in the general population with an allele frequency of 0.0004% (1/240630 alleles) in the Genome Aggregation Database. This variant causes a frameshift by deleting 5 nucleotides, so it is predicted to result in a truncated protein or mRNA subject to nonsense-mediated decay. Considering available information, this variant is classified as pathogenic. References: Alemar B et al.

The BRCA2 c.6405_6409del (p.N2135KfsX3) variant has been reported in heterozygosity in numerous individuals with breast, ovarian, or prostate cancer (PMID: 8988179, 21952622, 21324516, among others). It is also known as c.6402_6406delTAACT, 6630del5, and 6633del5 in the literature. This variant causes a frameshift at amino acid 2135 that results in premature termination 3 amino acids downstream. At this location, this is predicted to cause nonsense-mediated decay and result in an absent protein (loss of function). Loss of function variants in BRCA1 or BRCA2 are known to be pathogenic (PMID: 29446198). This variant was observed in 1/240630 chromosomes in the large and broad cohorts of the Genome Aggregation Database (http://gnomad.broadinstitute.org, PMID: 32461654). This variant has been reported in ClinVar (Variation ID: 38043). Based on the current evidence available, this variant is interpreted as pathogenic. (less)

The BRCA2 c.6405_6409del (p.Asn2135Lysfs*3) variant alters the translational reading frame of the BRCA2 mRNA and causes the premature termination of BRCA2 protein synthesis. This variant has been reported in the published literature in multiple affected individuals and families with breast and/or ovarian cancer (PMIDs: 36169650 (2022), 33646313 (2021), 33151324 (2021), 32341426 (2020), 32318955 (2020), 31825140 (2019), 31742824 (2020), 31090900 (2019), 30720863 (2019), 30287823 (2018), 30262796 (2018), 30078507 (2018), 29625052 (2018), 29161300 (2017), 28993434 (2018), 28831036 (2017), 28724667 (2017), 28324225 (2017), 27741520 (2016), 27425403 (2016), 21324516 (2011), 18489799 (2008), 17063270 (2007), 11179017 (2001), and 8988179 (1997)). The variant has been reported in breast cancer cases as well as in a control individual in a large scale breast cancer association study (PMID: 33471991 (2021), see also LOVD (http://databases.lovd.nl/shared/genes/BRCA2)). It has also been seen in biliary tract cancer (PMID: 36243179 (2022)), prostate cancer (PMIDs: 21952622 (2011) and 32853339 (2021)), and pancreatic cancer (PMID: 34399810 (2021)). The frequency of this variant in the general population, 0.0000042 (1/240630 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is consistent with pathogenicity. Based on the available information, this variant is classified as pathogenic. (less)

The p.Asn2135LysfsX3 variant in BRCA2 has been reported in at least 12 individuals with BRCA2-associated cancers (Gayther 1997, Wagner 1999, Risch 2001, Gomes 2007, Machackova … (more)
The p.Asn2135LysfsX3 variant in BRCA2 has been reported in at least 12 individuals with BRCA2-associated cancers (Gayther 1997, Wagner 1999, Risch 2001, Gomes 2007, Machackova 2008, Kote-Jarai 2011, Zhang 2011, de Juan 2015, Hirotsu 2015, Breast Cancer Information Core database:www.research.nhgri.nih.gov/bic/). This variant has also been identified in 1/240630 of pan-ethnic chromosomes by gnomAD (http://gnomad.broadinstitute.org). 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 2135 and leads to a premature termination codon 3 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 autosomal dominant HBOC. In addition, this variant was classified as Pathogenic on April 22, 2016 by the ClinGen-approved ENIGMA expert panel (ClinVar SCV000282424.1). 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, presence in multiple affected individuals and very low frequency in the general population.

Variant summary: BRCA2 c.6405_6409delCTTAA (p.Asn2135LysfsX3) 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 4.2e-06 in 240630 control chromosomes. c.6405_6409delCTTAA has been widely reported in the literature in multiple individuals affected with Hereditary Breast And Ovarian Cancer Syndrome (example, Rebbeck_2018). These data indicate that the variant is very likely to be associated with disease. Multiple clinical diagnostic laboratories and one expert panel (ENIGMA) have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All submitters classified the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. (less)

This variant deletes 5 nucleotides in exon 11 of the BRCA2 gene, creating a frameshift and premature translation stop signal. This variant is expected to result in an absent or non-functional protein product. This variant is also known as c.6402_6406del, 6630del5, and 6633del5 in the literature. This variant has been reported in individuals affected with breast and/or ovarian cancer (PMID: 8988179, 11179017, 17063270, 18489799, 21324516, 25802882, 27425403, 29161300, 30287823). This variant has been identified in 1/240630 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. (less)

The c.6405_6409del (p.Asn2135Lysfs*3) variant in the BRCA2 gene is located on the exon 11 and is predicted to cause shift of reading frame that introduces a premature translation termination codon (p.Asn2135Lysfs*3), resulting in an absent or disrupted protein product. The variant has been reported in multiple individuals with breast or ovarian cancer (PMID: 36171877, 31706072, 33606809, 30287823). Loss-of-function variants of BRCA2 are known to be pathogenic (PMID: 8988179, 11897832, 29446198). The variant is reported in ClinVar as pathogenic (ID: 38043) and reviewed by the expert panel. The variant is rare in the general population according to gnomAD (1/240630). Therefore, the c.6405_6409del (p.Asn2135Lysfs*3) variant of BRCA2 has been classified as pathogenic. (less)

The c.6405_6409delCTTAA pathogenic mutation, located in coding exon 10 of the BRCA2 gene, results from a deletion of 5 nucleotides at nucleotide positions 6405 to 6409, causing a translational frameshift with a predicted alternate stop codon (p.N2135Kfs*3). This mutation has been identified in multiple patients and families with hereditary breast and ovarian cancer syndrome (Gayther SA et al. Nat. Genet. 1997 Jan;15:103-5; Zhang S et al. Gynecol. Oncol. 2011 May;121:353-7; Kote-Jarai Z et al. Br. J. Cancer. 2011 Oct;105:1230-4; de Juan I et al. Fam. Cancer. 2015 Dec;14:505-13; Alemar B et al. Cancer Genet. 2016 Sep;209:417-422; Meisel C et al. Arch. Gynecol. Obstet. 2017 May;295(5):1227-1238; Li A et al. Gynecol. Oncol. 2018 10;151(1):145-152). Of note, this alteration is also designated as 6405delCTTAA, 6630del5, and 6633del5 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. (less)

The BRCA2 c.6405_6409del5 variant is predicted to result in a frameshift and premature protein termination (p.Asn2135Lysfs*3). In the literature, this variant may be referred to as N2135fs, 6630del5, 6633_6637delCTTAA, 6633del5, or rs80359584. This variant has been repeatedly reported in individuals with various cancers such as breast, ovarian, prostate, and acute leukemia (reported as 6630del5 in Table 1, Gayther et al. 1997. PubMed ID: 8988179; reported as 6633del5 in Table 1, Risch et al. 2001. PubMed ID: 11179017; Table 2, Lhotova et al. 2020. PubMed ID: 32295079; reported as rs80359584 in Table S3, Darst et al. 2021. PubMed ID: 32853339). This variant has been reported in 1 of over 240,000 individuals in gnomAD, indicating that it is rare. In ClinVar, this variant is interpreted as pathogenic (https://www.ncbi.nlm.nih.gov/clinvar/variation/38043/). Frameshift variants in BRCA2 are expected to be pathogenic. Taken together, this variant is interpreted as pathogenic. (less)

The BRCA2 p.Asn2135Lysfs*3 variant was identified in 12 of 11758 proband chromosomes (frequency: 0.001) from individuals or families with breast, ovarian, and prostate cancer (Borg 2010, de Juan 2015, Gayther 1997, Kote-Jarai 2011, Zhang 2011). The variant was also identified in dbSNP (ID: rs80359584) as “With Pathogenic allele”, in ClinVar (classified as pathogenic by Color Genomics, Invitae, GeneDx, Ambry Genetics, SCRP, BIC, and 11 clinical laboratories), COGR, LOVD 3.0, UMD-LSDB (67x causal), BIC Database (13x clinically important), and in ARUP Laboratories (definitely pathogenic). The variant was not identified in Cosmic, or the Zhejiang University Database, the 1000 Genomes Project, the NHLBI GO Exome Sequencing Project, the Exome Aggregation Consortium (August 8th 2016), or the Genome Aggregation Database (Feb 27, 2017). The c.6405_6409del variant is predicted to cause a frameshift, which alters the protein's amino acid sequence beginning at codon 2135 and leads to a premature stop codon at position 2137. 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 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. (less)

Comment:
The BRCA2 c.6405_6409delCTTAA variant (rs80359584) is reported in the medical literature in individuals with breast cancer or hereditary breast and ovarian cancer (Alemar 2016, Momozawa 2018, Wen 2018, Whitworth 2018). The variant is described as pathogenic by several sources in the ClinVar database (Variation ID: 38043) and is described in the general population with an allele frequency of 0.0004% (1/240630 alleles) in the Genome Aggregation Database. This variant causes a frameshift by deleting 5 nucleotides, so it is predicted to result in a truncated protein or mRNA subject to nonsense-mediated decay. Considering available information, this variant is classified as pathogenic. References: Alemar B et al.

Comment:
The BRCA2 c.6405_6409del (p.Asn2135Lysfs*3) variant alters the translational reading frame of the BRCA2 mRNA and causes the premature termination of BRCA2 protein synthesis. This variant has been reported in the published literature in multiple affected individuals and families with breast and/or ovarian cancer (PMIDs: 36169650 (2022), 33646313 (2021), 33151324 (2021), 32341426 (2020), 32318955 (2020), 31825140 (2019), 31742824 (2020), 31090900 (2019), 30720863 (2019), 30287823 (2018), 30262796 (2018), 30078507 (2018), 29625052 (2018), 29161300 (2017), 28993434 (2018), 28831036 (2017), 28724667 (2017), 28324225 (2017), 27741520 (2016), 27425403 (2016), 21324516 (2011), 18489799 (2008), 17063270 (2007), 11179017 (2001), and 8988179 (1997)). The variant has been reported in breast cancer cases as well as in a control individual in a large scale breast cancer association study (PMID: 33471991 (2021), see also LOVD (http://databases.lovd.nl/shared/genes/BRCA2)). It has also been seen in biliary tract cancer (PMID: 36243179 (2022)), prostate cancer (PMIDs: 21952622 (2011) and 32853339 (2021)), and pancreatic cancer (PMID: 34399810 (2021)). The frequency of this variant in the general population, 0.0000042 (1/240630 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is consistent with pathogenicity. Based on the available information, this variant is classified as pathogenic.
Comment:
Application of AMCG guidelines 2015. Used other ClinVar submission evidence where relevant. Loss of heterozygosity in tumours or immunohistochemistry abnormalities considered functional evidence of pathogenicity.
Comment:
The p.Asn2135LysfsX3 variant in BRCA2 has been reported in at least 12 individuals with BRCA2-associated cancers (Gayther 1997, Wagner 1999, Risch 2001, Gomes 2007, Machackova 2008, Kote-Jarai 2011, Zhang 2011, de Juan 2015, Hirotsu 2015, Breast Cancer Information Core database:www.research.nhgri.nih.gov/bic/). This variant has also been identified in 1/240630 of pan-ethnic chromosomes by gnomAD (http://gnomad.broadinstitute.org). 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 2135 and leads to a premature termination codon 3 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 autosomal dominant HBOC. In addition, this variant was classified as Pathogenic on April 22, 2016 by the ClinGen-approved ENIGMA expert panel (ClinVar SCV000282424.1). 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, presence in multiple affected individuals and very low frequency in the general population. ACMG/AMP Criteria applied: PVS1, PS4_Moderate, PM2.
Comment:
Variant summary: BRCA2 c.6405_6409delCTTAA (p.Asn2135LysfsX3) 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 4.2e-06 in 240630 control chromosomes. c.6405_6409delCTTAA has been widely reported in the literature in multiple individuals affected with Hereditary Breast And Ovarian Cancer Syndrome (example, Rebbeck_2018). These data indicate that the variant is very likely to be associated with disease. Multiple clinical diagnostic laboratories and one expert panel (ENIGMA) have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All submitters classified the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic.

Comment:
This sequence change creates a premature translational stop signal (p.Asn2135Lysfs*3) 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 (rs80359584, gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with breast, ovarian, and prostate cancer (PMID: 8988179, 11179017, 17063270, 21324516, 21952622, 25802882, 26026974). This variant is also known as c.6402_6406delTAACT, 6630del5, and 6633del5. ClinVar contains an entry for this variant (Variation ID: 38043). For these reasons, this variant has been classified as Pathogenic.
Comment:
This variant deletes 5 nucleotides in exon 11 of the BRCA2 gene, creating a frameshift and premature translation stop signal. This variant is expected to result in an absent or non-functional protein product. This variant is also known as c.6402_6406del, 6630del5, and 6633del5 in the literature. This variant has been reported in individuals affected with breast and/or ovarian cancer (PMID: 8988179, 11179017, 17063270, 18489799, 21324516, 25802882, 27425403, 29161300, 30287823). This variant has been identified in 1/240630 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.
Comment:
The c.6405_6409del (p.Asn2135Lysfs*3) variant in the BRCA2 gene is located on the exon 11 and is predicted to cause shift of reading frame that introduces a premature translation termination codon (p.Asn2135Lysfs*3), resulting in an absent or disrupted protein product. The variant has been reported in multiple individuals with breast or ovarian cancer (PMID: 36171877, 31706072, 33606809, 30287823). Loss-of-function variants of BRCA2 are known to be pathogenic (PMID: 8988179, 11897832, 29446198). The variant is reported in ClinVar as pathogenic (ID: 38043) and reviewed by the expert panel. The variant is rare in the general population according to gnomAD (1/240630). Therefore, the c.6405_6409del (p.Asn2135Lysfs*3) variant of BRCA2 has been classified as pathogenic.
Comment:
The c.6405_6409delCTTAA pathogenic mutation, located in coding exon 10 of the BRCA2 gene, results from a deletion of 5 nucleotides at nucleotide positions 6405 to 6409, causing a translational frameshift with a predicted alternate stop codon (p.N2135Kfs*3). This mutation has been identified in multiple patients and families with hereditary breast and ovarian cancer syndrome (Gayther SA et al. Nat. Genet. 1997 Jan;15:103-5; Zhang S et al. Gynecol. Oncol. 2011 May;121:353-7; Kote-Jarai Z et al. Br. J. Cancer. 2011 Oct;105:1230-4; de Juan I et al. Fam. Cancer. 2015 Dec;14:505-13; Alemar B et al. Cancer Genet. 2016 Sep;209:417-422; Meisel C et al. Arch. Gynecol. Obstet. 2017 May;295(5):1227-1238; Li A et al. Gynecol. Oncol. 2018 10;151(1):145-152). Of note, this alteration is also designated as 6405delCTTAA, 6630del5, and 6633del5 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.
Comment:
The BRCA2 c.6405_6409del5 variant is predicted to result in a frameshift and premature protein termination (p.Asn2135Lysfs*3). In the literature, this variant may be referred to as N2135fs, 6630del5, 6633_6637delCTTAA, 6633del5, or rs80359584. This variant has been repeatedly reported in individuals with various cancers such as breast, ovarian, prostate, and acute leukemia (reported as 6630del5 in Table 1, Gayther et al. 1997. PubMed ID: 8988179; reported as 6633del5 in Table 1, Risch et al. 2001. PubMed ID: 11179017; Table 2, Lhotova et al. 2020. PubMed ID: 32295079; reported as rs80359584 in Table S3, Darst et al. 2021. PubMed ID: 32853339). This variant has been reported in 1 of over 240,000 individuals in gnomAD, indicating that it is rare. In ClinVar, this variant is interpreted as pathogenic (https://www.ncbi.nlm.nih.gov/clinvar/variation/38043/). Frameshift variants in BRCA2 are expected to be pathogenic. Taken together, this variant is interpreted as pathogenic.
Comment:
The BRCA2 p.Asn2135Lysfs*3 variant was identified in 12 of 11758 proband chromosomes (frequency: 0.001) from individuals or families with breast, ovarian, and prostate cancer (Borg 2010, de Juan 2015, Gayther 1997, Kote-Jarai 2011, Zhang 2011). The variant was also identified in dbSNP (ID: rs80359584) as “With Pathogenic allele”, in ClinVar (classified as pathogenic by Color Genomics, Invitae, GeneDx, Ambry Genetics, SCRP, BIC, and 11 clinical laboratories), COGR, LOVD 3.0, UMD-LSDB (67x causal), BIC Database (13x clinically important), and in ARUP Laboratories (definitely pathogenic). The variant was not identified in Cosmic, or the Zhejiang University Database, the 1000 Genomes Project, the NHLBI GO Exome Sequencing Project, the Exome Aggregation Consortium (August 8th 2016), or the Genome Aggregation Database (Feb 27, 2017). The c.6405_6409del variant is predicted to cause a frameshift, which alters the protein's amino acid sequence beginning at codon 2135 and leads to a premature stop codon at position 2137. 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 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.

Variant allele predicted to encode a truncated non-functional protein.
Comment:
The BRCA2 c.6405_6409delCTTAA variant (rs80359584) is reported in the medical literature in individuals with breast cancer or hereditary breast and ovarian cancer (Alemar 2016, Momozawa 2018, Wen 2018, Whitworth 2018). The variant is described as pathogenic by several sources in the ClinVar database (Variation ID: 38043) and is described in the general population with an allele frequency of 0.0004% (1/240630 alleles) in the Genome Aggregation Database. This variant causes a frameshift by deleting 5 nucleotides, so it is predicted to result in a truncated protein or mRNA subject to nonsense-mediated decay. Considering available information, this variant is classified as pathogenic. References: Alemar B et al.

Comment:
The BRCA2 c.6405_6409del (p.Asn2135Lysfs*3) variant alters the translational reading frame of the BRCA2 mRNA and causes the premature termination of BRCA2 protein synthesis. This variant has been reported in the published literature in multiple affected individuals and families with breast and/or ovarian cancer (PMIDs: 36169650 (2022), 33646313 (2021), 33151324 (2021), 32341426 (2020), 32318955 (2020), 31825140 (2019), 31742824 (2020), 31090900 (2019), 30720863 (2019), 30287823 (2018), 30262796 (2018), 30078507 (2018), 29625052 (2018), 29161300 (2017), 28993434 (2018), 28831036 (2017), 28724667 (2017), 28324225 (2017), 27741520 (2016), 27425403 (2016), 21324516 (2011), 18489799 (2008), 17063270 (2007), 11179017 (2001), and 8988179 (1997)). The variant has been reported in breast cancer cases as well as in a control individual in a large scale breast cancer association study (PMID: 33471991 (2021), see also LOVD (http://databases.lovd.nl/shared/genes/BRCA2)). It has also been seen in biliary tract cancer (PMID: 36243179 (2022)), prostate cancer (PMIDs: 21952622 (2011) and 32853339 (2021)), and pancreatic cancer (PMID: 34399810 (2021)). The frequency of this variant in the general population, 0.0000042 (1/240630 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is consistent with pathogenicity. Based on the available information, this variant is classified as pathogenic.
Comment:
Application of AMCG guidelines 2015. Used other ClinVar submission evidence where relevant. Loss of heterozygosity in tumours or immunohistochemistry abnormalities considered functional evidence of pathogenicity.
Comment:
The p.Asn2135LysfsX3 variant in BRCA2 has been reported in at least 12 individuals with BRCA2-associated cancers (Gayther 1997, Wagner 1999, Risch 2001, Gomes 2007, Machackova 2008, Kote-Jarai 2011, Zhang 2011, de Juan 2015, Hirotsu 2015, Breast Cancer Information Core database:www.research.nhgri.nih.gov/bic/). This variant has also been identified in 1/240630 of pan-ethnic chromosomes by gnomAD (http://gnomad.broadinstitute.org). 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 2135 and leads to a premature termination codon 3 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 autosomal dominant HBOC. In addition, this variant was classified as Pathogenic on April 22, 2016 by the ClinGen-approved ENIGMA expert panel (ClinVar SCV000282424.1). 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, presence in multiple affected individuals and very low frequency in the general population. ACMG/AMP Criteria applied: PVS1, PS4_Moderate, PM2.

This sequence change creates a premature translational stop signal (p.Asn2135Lysfs*3) 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 (rs80359584, gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with breast, ovarian, and prostate cancer (PMID: 8988179, 11179017, 17063270, 21324516, 21952622, 25802882, 26026974). This variant is also known as c.6402_6406delTAACT, 6630del5, and 6633del5. ClinVar contains an entry for this variant (Variation ID: 38043). For these reasons, this variant has been classified as Pathogenic.
Comment:
This variant deletes 5 nucleotides in exon 11 of the BRCA2 gene, creating a frameshift and premature translation stop signal. This variant is expected to result in an absent or non-functional protein product. This variant is also known as c.6402_6406del, 6630del5, and 6633del5 in the literature. This variant has been reported in individuals affected with breast and/or ovarian cancer (PMID: 8988179, 11179017, 17063270, 18489799, 21324516, 25802882, 27425403, 29161300, 30287823). This variant has been identified in 1/240630 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.
Comment:
The c.6405_6409del (p.Asn2135Lysfs*3) variant in the BRCA2 gene is located on the exon 11 and is predicted to cause shift of reading frame that introduces a premature translation termination codon (p.Asn2135Lysfs*3), resulting in an absent or disrupted protein product. The variant has been reported in multiple individuals with breast or ovarian cancer (PMID: 36171877, 31706072, 33606809, 30287823). Loss-of-function variants of BRCA2 are known to be pathogenic (PMID: 8988179, 11897832, 29446198). The variant is reported in ClinVar as pathogenic (ID: 38043) and reviewed by the expert panel. The variant is rare in the general population according to gnomAD (1/240630). Therefore, the c.6405_6409del (p.Asn2135Lysfs*3) variant of BRCA2 has been classified as pathogenic.
Comment:
The c.6405_6409delCTTAA pathogenic mutation, located in coding exon 10 of the BRCA2 gene, results from a deletion of 5 nucleotides at nucleotide positions 6405 to 6409, causing a translational frameshift with a predicted alternate stop codon (p.N2135Kfs*3). This mutation has been identified in multiple patients and families with hereditary breast and ovarian cancer syndrome (Gayther SA et al. Nat. Genet. 1997 Jan;15:103-5; Zhang S et al. Gynecol. Oncol. 2011 May;121:353-7; Kote-Jarai Z et al. Br. J. Cancer. 2011 Oct;105:1230-4; de Juan I et al. Fam. Cancer. 2015 Dec;14:505-13; Alemar B et al.

Of note, this alteration is also designated as 6405delCTTAA, 6630del5, and 6633del5 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.
Comment:
The BRCA2 c.6405_6409del5 variant is predicted to result in a frameshift and premature protein termination (p.Asn2135Lysfs*3). In the literature, this variant may be referred to as N2135fs, 6630del5, 6633_6637delCTTAA, 6633del5, or rs80359584. This variant has been repeatedly reported in individuals with various cancers such as breast, ovarian, prostate, and acute leukemia (reported as 6630del5 in Table 1, Gayther et al. 1997. PubMed ID: 8988179; reported as 6633del5 in Table 1, Risch et al. 2001. PubMed ID: 11179017; Table 2, Lhotova et al. 2020. PubMed ID: 32295079; reported as rs80359584 in Table S3, Darst et al. 2021. PubMed ID: 32853339). This variant has been reported in 1 of over 240,000 individuals in gnomAD, indicating that it is rare. In ClinVar, this variant is interpreted as pathogenic (https://www.ncbi.nlm.nih.gov/clinvar/variation/38043/). Frameshift variants in BRCA2 are expected to be pathogenic. Taken together, this variant is interpreted as pathogenic.

The BRCA2 p.Asn2135Lysfs*3 variant was identified in 12 of 11758 proband chromosomes (frequency: 0.001) from individuals or families with breast, ovarian, and prostate cancer (Borg 2010, de Juan 2015, Gayther 1997, Kote-Jarai 2011, Zhang 2011). The variant was also identified in dbSNP (ID: rs80359584) as “With Pathogenic allele”, in ClinVar (classified as pathogenic by Color Genomics, Invitae, GeneDx, Ambry Genetics, SCRP, BIC, and 11 clinical laboratories), COGR, LOVD 3.0, UMD-LSDB (67x causal), BIC Database (13x clinically important), and in ARUP Laboratories (definitely pathogenic). The variant was not identified in Cosmic, or the Zhejiang University Database, the 1000 Genomes Project, the NHLBI GO Exome Sequencing Project, the Exome Aggregation Consortium (August 8th 2016), or the Genome Aggregation Database (Feb 27, 2017). The c.6405_6409del variant is predicted to cause a frameshift, which alters the protein's amino acid sequence beginning at codon 2135 and leads to a premature stop codon at position 2137. 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 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.
