| Ambry Genetics | RCV000566717 | SCV000673762 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-06-07 | criteria provided, single submitter | clinical testing | The p.T263M variant (also known as c.788C>T), located in coding exon 1 of the MET gene, results from a C to T substitution at nucleotide position 788. The threonine at codon 263 is replaced by methionine, an amino acid with similar properties. This amino acid position is highly 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. |

RCV001312222 | SCV000749642 | uncertain significance | Renal cell carcinoma | 2025-01-23 | criteria provided, single submitter | clinical testing | This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 263 of the MET protein (p.Thr263Met). This variant is present in population databases (rs764052874, gnomAD 0.005%). 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: 485747). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed for this missense variant. However, the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on MET 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. |

RCV000628736 | SCV001324823 | uncertain significance | Papillary renal cell carcinoma type 1 | 2018-01-13 | criteria provided, single submitter | clinical testing | This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. |
