Ambry Genetics | RCV000570605 | SCV000673137 | uncertain significance | Hereditary cancer-predisposing syndrome | 2017-09-15 | criteria provided, single submitter | clinical testing | The p.I1851F variant (also known as c.5551A>T), located in coding exon 10 of the BRCA2 gene, results from an A to T substitution at nucleotide position 5551. The isoleucine at codon 1851 is replaced by phenylalanine, an amino acid with highly similar properties. This amino acid position is poorly 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. |

RCV001213951 | SCV001385612 | uncertain significance | Hereditary breast ovarian cancer syndrome | 2021-03-13 | criteria provided, single submitter | clinical testing | 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 are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with BRCA2-related conditions. ClinVar contains an entry for this variant (Variation ID: 485446). This variant is not present in population databases (ExAC no frequency). This sequence change replaces isoleucine with phenylalanine at codon 1851 of the BRCA2 protein (p.Ile1851Phe). The isoleucine residue is weakly conserved and there is a small physicochemical difference between isoleucine and phenylalanine. |
