This variant results in the deletion of exon 10 (c.671-215_901del) of the BRCA1 gene. RNA analysis indicates that this variant induces altered splicing and may result in an absent or disrupted protein product. This variant has been observed in individual(s) with breast and/or ovarian cancer (PMID: 29446198). ClinVar contains an entry for this variant (Variation ID: 267615). Studies have shown that this variant results in skipping of exon 10 or part of exon 10 and introduces a premature termination codon (Invitae). The resulting mRNA is expected to undergo nonsense-mediated decay. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic.

Record last updated Oct 08, 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.
