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]

The MET c.901A>G, p.Thr301Ala variant (rs201687037), to our knowledge, has not been reported in the medical literature; however, this variant is listed in the ClinVar database (Variation ID: 167292). This variant is found in the general population with an overall allele frequency of 0.03% (81/280,300 alleles) in the Genome Aggregation Database. The threonine at codon 301 is moderately conserved, and computational analyses are uncertain whether this variant is neutral or deleterious (REVEL: 0.243). Based on the available information, the clinical significance of this variant is uncertain. -

The MET p.T301A variant was identified in one individual with colon cancer (Rohlin_2017_PMID: 27696107). The variant was identified in dbSNP (ID: rs201687037), ClinVar (classified as uncertain significance by EGL Genetic Diagnostics and Invitae; and as likely benign by Ambry Genetics), and COSMIC (lung, prostate, endometrium). The variant was identified in control databases in 81 of 280300 chromosomes at a frequency of 0.0002890, and was observed at the highest frequency in the European (non-Finnish) population in 71 of 128168 chromosomes (freq: 0.0005540) (Genome Aggregation Database March 6, 2019, v2.1.1). The p.T301 residue is conserved in mammals and computational analyses (MUT Assesor, PolyPhen-2, SIFT, MutationTaster, Revel, FATHMM, MetaLR, DANN) provide inconsistent predictions regarding the impact to the protein; this information is not very predictive of pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (Splice AI exome) do not predict an impact on splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance. -

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
