Ambry Genetics | RCV001017368 | SCV001178442 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-01-07 | criteria provided, single submitter | clinical testing | The p.N372D variant (also known as c.1114A>G), located in coding exon 9 of the BRCA2 gene, results from an A to G substitution at nucleotide position 1114. The asparagine at codon 372 is replaced by aspartic acid, an amino acid with highly 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. |

RCV001319297 | SCV001510037 | uncertain significance | Hereditary breast ovarian cancer syndrome | 2020-05-21 | criteria provided, single submitter | clinical testing | This variant is not present in population databases (ExAC no frequency). This sequence change replaces asparagine with aspartic acid at codon 372 of the BRCA2 protein (p.Asn372Asp). The asparagine residue is weakly conserved and there is a small physicochemical difference between asparagine and aspartic acid. This variant has not been reported in the literature in individuals with BRCA2-related conditions. ClinVar contains an entry for this variant (Variation ID: 822206). 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. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The aspartic acid amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. |
