For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 417831). This premature translational stop signal has been observed in individual(s) with a personal and/or family history of breast and/or ovarian cancer (PMID: 29339979, 29566657). This variant is present in population databases (no rsID available, gnomAD 0.003%). This sequence change creates a premature translational stop signal (p.Asn1215Ilefs*2) 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). (less)

Record last updated Nov 25, 2024
This date represents the last time this VCV record was updated. The update may be due to an update to one of the included submitted records (SCVs), or due to an update that ClinVar made to the variant such as adding HGVS expressions or a rs number. So this date may be different from the date of the “most recent submission” reported at the top of this page.
