GeneDx RCV000159906 SCV000210023 pathogenic not provided 2017-10-25 criteria provided, single submitter clinical testing This deletion of 2 nucleotides in BRCA1 is denoted c.2411_2412delAG at the cDNA level and p.Gln804LeufsX5 (Q804LfsX5) at the protein level. The normal sequence, with the bases that are deleted in brackets, is AGTC[delAG]TGTG. The deletion causes a frameshift, which changes a Glutamine to a Leucine at codon 804, and creates a premature stop codon at position 5 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. BRCA1 c.2411_2412delAG, also published as 2411delAG and 2530delAG, has been reported in several women with a history of breast and/or ovarian cancer (Rothfuss 2000, Pal 2005, Pohlreich 2005, Chisholm 2008, Machackova 2008, Spearman 2008, Couch 2015, Meisel 2017). We consider this variant to be pathogenic.

Integrated Genetics/Laboratory Corporation of America RCV000047829 SCV000698948 pathogenic Hereditary breast and ovarian cancer syndrome 2016-02-22 criteria provided, single submitter clinical testing Variant summary: The variant of interest causes a frameshift/truncating mutation and is predicted to have a "disease-causing" outcome by mutation taster. It is absent from the large and broad cohorts of the NHLBI-ES and ExAC projects while it was reported in several HBOC spectrum patients indicating pathogenicity. Furthermore, several reputable databases and clinical diagnostic laboratories via ClinVar classify variant as Pathogenic (without evidence to independently evaluate). Considering all, the variant shows strong evidence for pathogenicity; it as a truncating mutation, absent from the general population and databases classify it as pathogenic. Therefore, the variant was classified as Pathogenic.
Invitae RCV000047829 SCV000075842 pathogenic Hereditary breast and ovarian cancer syndrome 2018-11-29 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Gln804Leufs*5) in the BRCA1 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: 10667595, 16168118, 18489799, 26681312, 25777348). This variant is also known as 2530delAG in the literature. ClinVar contains an entry for this variant (Variation ID: 37466). An experimental study has shown that lymphocytes of individuals who carry this variant generate higher numbers of micronuclei after radiation exposure and are deficient in repair of radiation-induced DNA damage (PMID: 10667595). Loss-of-function variants in BRCA1 are known to be pathogenic (PMID: 20104584). For these reasons, this variant has been classified as Pathogenic.
