Renal cell carcinoma Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Nov 13, 2023 | This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 339 of the MET protein (p.Asp339Asn). This variant is present in population databases (no rsID available, gnomAD 0.0009%). 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: 454173). 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) has been performed at Invitae 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. - |
Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Feb 12, 2022 | The p.D339N variant (also known as c.1015G>A), located in coding exon 1 of the MET gene, results from a G to A substitution at nucleotide position 1015. The aspartic acid at codon 339 is replaced by asparagine, an amino acid with highly similar properties. This amino acid position is conserved. 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. - |
