Invitae RCV000044773 SCV000072786 pathogenic Hereditary breast and ovarian cancer syndrome 2018-11-16 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Ser1951Trpfs*11) 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 several individuals affected with breast and/or ovarian cancer (PMID: 22752604, 22970155, 18821011, 26183948, 19805903, 29335924, 29487695, 27882536). This variant is also known as 6079delAGTT in the literature. ClinVar contains an entry for this variant (Variation ID: 38001). Loss-of-function variants in BRCA2 are known to be pathogenic (PMID: 20104584). For these reasons, this variant has been classified as Pathogenic.

GeneDx RCV000254645 SCV000210772 pathogenic not provided 2016-11-09 criteria provided, single submitter clinical testing This pathogenic variant is denoted BRCA2 c.5851_5854delAGTT at the cDNA level and p.Ser1951TrpfsX11 (S1951WfsX11) at the protein level. The normal sequence, with the bases that are deleted in brackets, is TGTT[delAGTT]TGGA. The deletion causes a frameshift, changing a Serine to a Tryptophan at codon 1951, and creates a premature stop codon at position 11 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.5851_5854delAGTT, also reported as 6079del4 or 6079_6082delAGTT using alternate nomenclature, has been seen in association with breast and/or ovarian cancer (Díez 2003, Kwong 2009, Papi 2009, Vaidyanathan 2009, Juwle 2012, Dodova 2015). We consider this variant to be pathogenic.

ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories RCV000254645 SCV000883482 pathogenic not provided 2017-05-17 criteria provided, single submitter clinical testing The BRCA2 c.5851_5854delAGTT; p.Ser1951fs variant (also known as 6079delAGTT) has been reported in several individuals with hereditary breast and ovarian cancer syndrome (Dodova 2015, Juwle 2012, Kwong 2012, Papi 2009, Vaidyanathan 2009). This variant is reported in ClinVar (Variation ID: 38001), and is absent from the general population databases (1000 Genomes Project, Exome Variant Server, Genome Aggregation Database). This variant creates a frameshift and is predicted to result in a truncated protein or absent transcript, and is considered pathogenic.
