Description

This sequence change creates a premature translational stop signal (p.Gln166*) in the BARD1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in BARD1 are known to be pathogenic (PMID: 20077502, 21344236). This variant is present in population databases (rs786202500, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with BARD1-related conditions. ClinVar contains an entry for this variant (Variation ID: 185846). For these reasons, this variant has been classified as Pathogenic.
