Ambry Genetics | RCV000165818 | SCV000216565 | uncertain significance | Hereditary cancer-predisposing syndrome | 2018-07-20 | criteria provided, single submitter | clinical testing | The p.D1864G variant (also known as c.5591A>G), located in coding exon 10 of the BRCA2 gene, results from an A to G substitution at nucleotide position 5591. The aspartic acid at codon 1864 is replaced by glycine, an amino acid with similar properties. This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |

RCV000820675 | SCV000961397 | uncertain significance | Hereditary breast ovarian cancer syndrome | 2020-10-20 | criteria provided, single submitter | clinical testing | This sequence change replaces aspartic acid with glycine at codon 1864 of the BRCA2 protein (p.Asp1864Gly). The aspartic acid residue is weakly conserved and there is a moderate physicochemical difference between aspartic acid and glycine. This variant is not present in population databases (ExAC no frequency). This variant has been reported in individuals in the Leiden Open-source Variation Database (PMID: 21520333). ClinVar contains an entry for this variant (Variation ID: 186254). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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. |
