Variant summary
Our verdict is Pathogenic. Variant got 12 ACMG points: 12P and 0B. PVS1PM2PP5_Moderate
The NM_000059.4(BRCA2):c.5427C>A(p.Cys1809Ter) variant causes a stop gained change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★). Synonymous variant affecting the same amino acid position (i.e. C1809C) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Apr 08, 2022 | ClinVar contains an entry for this variant (Variation ID: 660602). For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals affected with BRCA2-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Cys1809*) 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). - |
