RCV001341459 | SCV001535336 | uncertain significance | Renal cell carcinoma | 2023-09-14 | 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. This sequence change replaces leucine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 455 of the MET protein (p.Leu455Ile). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with MET-related conditions. ClinVar contains an entry for this variant (Variation ID: 1038186). 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 MET protein function. |

Ambry Genetics | RCV002384462 | SCV002697594 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-07-17 | criteria provided, single submitter | clinical testing | The p.L455I variant (also known as c.1363C>A), located in coding exon 2 of the MET gene, results from a C to A substitution at nucleotide position 1363. The leucine at codon 455 is replaced by isoleucine, an amino acid with highly similar properties. This amino acid position is highly 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. |
