RCV000464981 | SCV000549588 | uncertain significance | Hereditary breast ovarian cancer syndrome | 2016-05-03 | criteria provided, single submitter | clinical testing | This sequence change replaces lysine with glutamic acid at codon 1533 of the BRCA2 protein (p.Lys1533Glu). The lysine residue is weakly conserved and there is a small physicochemical difference between lysine and glutamic acid. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a BRCA2-related disease. Experimental studies have shown that this missense change does not significantly alter the interaction between BRCA2 and RAD51 in cell culture (PMID: 21601571). In summary, this variant is a rare missense change that is not predicted to affect protein function. There is no indication that it causes disease, but the available evidence is currently insufficient to prove that conclusively. Therefore, it has been classified as a Variant of Uncertain Significance. |

RCV004802005 | SCV005424443 | uncertain significance | BRCA2-related cancer predisposition | 2024-02-22 | criteria provided, single submitter | clinical testing | This missense variant replaces lysine with glutamic acid at codon 1533 of the BRCA2 protein. Computational prediction suggests that this variant may not impact protein structure and function. This variant did not impact BRCA2-RAD51 interaction in a mammalian two-hybrid assay (PMID: 21601571). This variant has not been reported in individuals affected with BRCA2-related disorders in the literature, but has been reported in an unaffected individual (PMID: 33471991; Leiden Open Variation Database DB-ID BRCA2_008244). This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. |
