Description

For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals with BRCA2-related conditions. ClinVar contains an entry for this variant (Variation ID: 51321). This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Leu88Argfs*8) 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).
