Evidence-based Network for the Interpretation of Germline Mutant Alleles (ENIGMA) RCV000257548 SCV000323448 pathogenic Breast-ovarian cancer, familial, susceptibility to, 1 2016-10-18 reviewed by expert panel curation Variant allele predicted to encode a truncated non-functional protein.
Ambry Genetics RCV000221355 SCV000277622 pathogenic Hereditary cancer-predisposing syndrome 2015-07-30 criteria provided, single submitter clinical testing The c.2386_2387delACinsT pathogenic mutation (also known as c.2386delACinsT or 2505delACinsT), located in coding exon 9 of the BRCA1 gene, results from the deletion of two nucleotides and insertion of one nucleotide causing a translational frameshift with a predicted alternate stop codon. Since frameshifts are typically deleterious in nature, this alteration is interpreted as a disease-causing mutation (ACMG Recommendations for Standards for Interpretation and Reporting of Sequence Variations. Revision 2007. Genet Med. 2008;10:294).

Invitae RCV000696458 SCV000825021 pathogenic Hereditary breast ovarian cancer syndrome 2023-12-21 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Thr796*) in the BRCA1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in BRCA1 are known to be pathogenic (PMID: 20104584). Information on the frequency of this variant in the gnomAD database is not available, as this variant may be reported differently in the database. This premature translational stop signal has been observed in individual(s) with ovarian cancer (PMID: 28888541). For these reasons, this variant has been classified as Pathogenic.
Quest Diagnostics Nichols Institute San Juan Capistrano RCV000985386 SCV001133527 pathogenic not provided 2019-01-04 criteria provided, single submitter clinical testing The variant creates a premature nonsense codon, and is therefore predicted to result in the loss of a functional protein. Found in at least one symptomatic patient, and not found in general population data.
