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]

Significance: Benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

Variant summary: MET c.607T>A (p.Ser203Thr) results in a conservative amino acid change located in the Sema domain (IPR001627) of the encoded protein sequence. Five of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.0006 in 248020 control chromosomes in the gnomAD database, including 1 homozygote. The observed variant frequency is approximately 400 fold of the estimated maximal expected allele frequency for a pathogenic variant in MET causing Papillary Renal Cell Carcinoma phenotype (1.5e-06), strongly suggesting that the variant is benign. To our knowledge, no occurrence of c.607T>A in individuals affected with Papillary Renal Cell Carcinoma and no experimental evidence demonstrating its impact on protein function have been reported. Four clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation and classified the variant predominantly as benign/likely benign (n=4). Based on the evidence outlined above, the variant was classified as benign. -
