Ambry Genetics | RCV000164853 | SCV000215536 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-03-08 | criteria provided, single submitter | clinical testing | The p.R1555K variant (also known as c.4664G>A), located in coding exon 13 of the BRCA1 gene, results from a G to A substitution at nucleotide position 4664. The arginine at codon 1555 is replaced by lysine, an amino acid with highly similar properties. This amino acid position is not well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |

RCV000799806 | SCV000939487 | uncertain significance | Hereditary breast ovarian cancer syndrome | 2022-04-29 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with lysine, which is basic and polar, at codon 1555 of the BRCA1 protein (p.Arg1555Lys). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with BRCA1-related conditions. ClinVar contains an entry for this variant (Variation ID: 185428). 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 BRCA1 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. |
