GeneDx RCV000219562 SCV000278871 pathogenic not provided 2017-07-26 criteria provided, single submitter clinical testing This deletion of 4 nucleotides in BRCA2 is denoted c.6644_6647delACTC at the cDNA level and p.Tyr2215SerfsX13 (Y2215SfsX13) at the protein level. The normal sequence, with the bases that are deleted in brackets, is ACTT[delACTC]CAAA. The deletion causes a frameshift, which changes a Tyrosine to a Serine at codon 2215, and creates a premature stop codon at position 13 of the new reading frame. This variant is predicted to cause loss of normal protein function through either protein truncation or nonsense-mediated mRNA decay. BRCA2 c.6644_6647delACTC, previously reported as 6872_6875delACTC and 6872del4, has been reported in association with breast and ovarian cancer and is considered to be pathogenic (Serova-Sinilnikova 1997, Verhoog 2001, Lewis 2006, Zhang 2011, Caputo 2012, Tung 2015).
Integrated Genetics/Laboratory Corporation of America RCV000416517 SCV000494433 pathogenic Hereditary breast and ovarian cancer syndrome 2015-06-05 criteria provided, single submitter clinical testing Variant Summary: This deletion of 4 nucleotides results in a frameshift which leads to a premature termination codon 13 amino acids downstream. This alteration is then predicted to lead to a truncated or absent protein. The variant has been reported in numerous families and individuals with HBOC, clearly confirming segregation with disease; the has been reported as a French founder mutation (Caputo_2012). The variant is absent in a large control population with diverse ethnicities (ExAC). Several clinical labs and reputable databases have classified the variant as "pathogenic", inlcuding ARUP, SCRP, BIC, Ambry Genetics, and UMD. Taken together, this variant is classified as pathogenic.
Invitae RCV000416517 SCV000073019 pathogenic Hereditary breast and ovarian cancer syndrome 2019-01-05 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Tyr2215Serfs*13) in the BRCA2 gene. It is expected to result in an absent or disrupted protein product. This variant is not present in population databases (ExAC no frequency). This variant has been observed in individuals affected with breast and/or ovarian cancer (PMID: 9150172, 22144684, 21324516, 16683254, 21120943). This variant is also known as 6872del4 or 6872delACTC in the literature. ClinVar contains an entry for this variant (Variation ID: 38060). Loss-of-function variants in BRCA2 are known to be pathogenic (PMID: 20104584). For these reasons, this variant has been classified as Pathogenic.
Laboratory for Molecular Medicine,Partners HealthCare Personalized Medicine RCV000416517 SCV000605813 pathogenic Hereditary breast and ovarian cancer syndrome 2017-01-27 criteria provided, single submitter clinical testing The p.Tyr2215fs variant in BRCA2 has been reported in >25 individuals with BRCA2 -associated cancers and segregated with disease in 5 relatives from 2 families ( Serova-Sinilnikova 1997, Caputo 2012, Zhang 2011, Risch 2001, Verhoog 2001, and Breast Cancer Information Core (BIC) database). It was also absent from large po pulation studies. This variant is predicted to cause a frameshift, which alters the protein?s amino acid sequence beginning at position 2215 and leads to a prem ature termination codon 13 amino acids downstream. This alteration is then predi cted to lead to a truncated or absent protein. Heterozygous loss of function of the BRCA2 gene is an established disease mechanism in hereditary breast and ovar ian cancer (HBOC). In addition, this variant was classified as Pathogenic on Sep tember 8, 2016 by the ClinGen-approved ENIGMA expert panel (ClinVar SCV000301085 .2). In summary, this variant meets criteria to be classified as pathogenic for HBOC in an autosomal dominant manner.
