Description

This sequence change creates a premature translational stop signal (p.Glu2924*) in the BRCA2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in BRCA2 are known to be pathogenic (PMID: 20104584). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with high risk for breast and/or ovarian cancer (PMID: 29446198). ClinVar contains an entry for this variant (Variation ID: 52675). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. For these reasons, this variant has been classified as Pathogenic.
