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]

MET links:

COMETT (HGNC:51196): (cytosolic oncogenic antisense to MET transcript) This gene encodes a natural antisense transcript highly expressed in papillary thyroid carcinomas harboring BRAF V600E mutation or RET gene rearrangements. This lncRNA induces the downstream MAPK pathway and is part of a co-expression network including different oncogenes belonging to the MAPK and PI3H/AKT pathways. In thyroid carcinomas, this gene has oncogenic properties associated with increased proliferation and drug resistance. [provided by RefSeq, Jan 2020]

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.
