Ambry Genetics | RCV000166334 | SCV000217120 | uncertain significance | Hereditary cancer-predisposing syndrome | 2024-03-29 | criteria provided, single submitter | clinical testing | The p.G578D variant (also known as c.1733G>A), located in coding exon 9 of the BRCA2 gene, results from a G to A substitution at nucleotide position 1733. The glycine at codon 578 is replaced by aspartic acid, an amino acid with similar properties. This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on the available evidence, the clinical significance of this alteration remains unclear. |

RCV000166334 | SCV000688720 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-04-05 | criteria provided, single submitter | clinical testing | This missense variant replaces glycine with aspartic acid at codon 578 of the BRCA2 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been reported in 1 individual affected with breast cancer (PMID: 33471991; Leiden Open Variation Database DB-ID BRCA2_007879). This variant has been identified in 1/250840 chromosomes 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. |

RCV001854359 | SCV002113050 | uncertain significance | Hereditary breast ovarian cancer syndrome | 2023-10-09 | criteria provided, single submitter | clinical testing | This sequence change replaces glycine, which is neutral and non-polar, with aspartic acid, which is acidic and polar, at codon 578 of the BRCA2 protein (p.Gly578Asp). This variant is present in population databases (rs398122730, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with BRCA2-related conditions. ClinVar contains an entry for this variant (Variation ID: 91756). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt BRCA2 protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. |
