Genes affected
MET (HGNC:7029): (MET proto-oncogene, receptor tyrosine kinase) This gene encodes a member of the receptor tyrosine kinase family of proteins and the product of the proto-oncogene MET. The encoded preproprotein is proteolytically processed to generate alpha and beta subunits that are linked via disulfide bonds to form the mature receptor. Further processing of the beta subunit results in the formation of the M10 peptide, which has been shown to reduce lung fibrosis. Binding of its ligand, hepatocyte growth factor, induces dimerization and activation of the receptor, which plays a role in cellular survival, embryogenesis, and cellular migration and invasion. Mutations in this gene are associated with papillary renal cell carcinoma, hepatocellular carcinoma, and various head and neck cancers. Amplification and overexpression of this gene are also associated with multiple human cancers. [provided by RefSeq, May 2016]

Uncertain significance, criteria provided, single submitter | curation | Sema4, Sema4 | Apr 22, 2021 | - - |
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Feb 12, 2022 | The p.D981G variant (also known as c.2942A>G) is located in coding exon 13 of the MET gene. The aspartic acid at codon 981 is replaced by glycine, an amino acid with similar properties. This change occurs in the first base pair of coding exon 13. This amino acid position is conserved. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. - |
Renal cell carcinoma Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Apr 28, 2023 | An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 454227). This variant has not been reported in the literature in individuals affected with MET-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces aspartic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 981 of the MET protein (p.Asp981Gly). 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. - |
