Evidence-based Network for the Interpretation of Germline Mutant Alleles (ENIGMA) RCV000031188 SCV000282332 pathogenic Breast-ovarian cancer, familial 1 2016-04-22 reviewed by expert panel curation Variant allele predicted to encode a truncated non-functional protein.
Invitae RCV000048631 SCV000076644 pathogenic Hereditary breast and ovarian cancer syndrome 2019-01-02 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Tyr1563*) 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 particular variant has been reported in the literature in individuals affected with hereditary breast and ovarian cancer (PMID: 8554067, 23110154, 25066507, 20727672, 27167707). This variant is also known as 4808C>G in the literature. ClinVar contains an entry for this variant (Variation ID: 37607). Loss-of-function variants in BRCA1 are known to be pathogenic (PMID: 20104584). For these reasons, this variant has been classified as Pathogenic.

GeneDx RCV000159994 SCV000210185 pathogenic not provided 2018-05-29 criteria provided, single submitter clinical testing This pathogenic variant is denoted BRCA1 c.4689C>G at the cDNA level and Tyr1563Ter (Y1563X) at the protein level. The substitution creates a nonsense variant, which changes a Tyrosine to a premature stop codon (TAC>TAG), and is predicted to cause loss of normal protein function through either protein truncation or nonsense-mediated mRNA decay. This variant, also denoted 4808C>G using alternate nomenclature, has been reported in association with familial breast cancer and/or ovarian cancer and is considered pathogenic (Serova 1996, Shih 2002, Turkovic 2010, Schneegans 2012, Wong-Brown 2015).

Mutation taster predicts a damaging outcome for this variant. The variant is not found in 120204 control chromosomes and it was reported in several HBOC spectrum patients via publications and databases suggesting a disease causing impact. Furthermore, truncations downstream of this position have been classified as pathogenic by our laboratory (e.g.: p.Glu1725X, p.Arg1751X, p.Ser1796X, p.Trp1815X, p.Arg1835X) indicating pathogenicity. In addition, several clinical laboratories and reputable databases classified this variant as Pathogenic. Taken together, this variant was classified as Pathogenic.

Human Genome Sequencing Center Clinical Lab,Baylor College of Medicine RCV000031188 SCV000839898 pathogenic Breast-ovarian cancer, familial 1 2017-06-06 criteria provided, single submitter clinical testing The c.4689C>G (p.Tyr1563*) variant in the BRCA1 gene has been detected multiple patients with breast cancer and/or ovarian cancer [PMID 8554067, 23110154]. This variant creates a premature stop codon at amino acid position 1563 of the BRCA1 protein. This variant is thus predicted to result in a loss of function of the protein. This variant has not been observed in the ExAC population database. This variant is thus classified as pathogenic.
