Invitae | RCV000803204 | SCV000943066 | uncertain significance | Hereditary breast ovarian cancer syndrome | 2020-12-31 | 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: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with BRCA1-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces leucine with arginine at codon 998 of the BRCA1 protein (p.Leu998Arg). The leucine residue is moderately conserved and there is a moderate physicochemical difference between leucine and arginine. |

Ambry Genetics | RCV001175762 | SCV002750710 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-02-14 | criteria provided, single submitter | clinical testing | The p.L998R variant (also known as c.2993T>G), located in coding exon 9 of the BRCA1 gene, results from a T to G substitution at nucleotide position 2993. The leucine at codon 998 is replaced by arginine, an amino acid with dissimilar 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. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
