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]

Submissions by phenotype

Renal cell carcinoma Uncertain:1
Oct 04, 2023
Labcorp Genetics (formerly Invitae), Labcorp
Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This sequence change replaces threonine, which is neutral and polar, with alanine, which is neutral and non-polar, at codon 1010 of the MET protein (p.Thr1010Ala). This variant is present in population databases (rs774433287, gnomAD 0.009%). This missense change has been observed in individual(s) with lung cancer (PMID: 15592501). This variant is also known as p.Thr992Ala (T992A). ClinVar contains an entry for this variant (Variation ID: 411908). 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. 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. -

Papillary renal cell carcinoma type 1 Uncertain:1
Oct 06, 2022
St. Jude Molecular Pathology, St. Jude Children's Research Hospital
Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The MET c.3028A>G (p.Thr1010Ala) missense change has a maximum frequency of 0.0093% in gnomAD v2.1.1 (https://gnomad.broadinstitute.org). The in silico tool REVEL is inconclusive about a pathogenic or benign effect of this variant on protein function, and to our knowledge functional studies have not been performed. To our knowledge, this variant has not been reported in individuals with hereditary papillary renal cell carcinoma. In summary, the evidence currently available is insufficient to determine the clinical significance of this variant. It has therefore been classified as of uncertain significance. -

Hereditary cancer-predisposing syndrome Uncertain:1
Nov 01, 2023
Ambry Genetics
Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The p.T1010A variant (also known as c.3028A>G), located in coding exon 13 of the MET gene, results from an A to G substitution at nucleotide position 3028. The threonine at codon 1010 is replaced by alanine, an amino acid with similar properties. This alteration has been reported in an individual diagnosed with lung adenocarcinoma at age 58 (Zaffaroni D et al. Oncogene, 2005 Feb;24:1084-90). 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. -
