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]

Variant summary: The MET c.144G>A (p.Ala48Ala) variant causes a synonymous change involving a non-conserved nucleotide. The variant of interest was observed in the large, broad control population, ExAC, with an allele frequency of 3980/120670 (1/30, 106 homozygotes), which significantly exceeds the estimated maximal expected allele frequency for a pathogenic MET variant of 1/666666, suggesting this variant is likely a benign polymorphism. Multiple reputable clinical laboratories cite the variant as "benign." Therefore, the variant has been classified as Benign. -

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -

Significance: Benign
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This alteration is classified as 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. -

BA1, BS2_Supporting, BP4, BP7 c.144G>A, located in exon 2 of the MET gene, is predicted to result in no amino acid change, p.(Ala48=) (BP7). The variant allele was found in 8553/266234, with a filtering allele frequency of 0,050% at 99% confidence within the non-Finnish European population and has been observed in homozygous state in 210 control chromosomes in the gnomAD v2.1.1 database (non-cancer data set) (BA1 and BS2_supp). The SpliceAI algorithm predicts no significant impact on splicing (BP4). To our knowledge, no well-established functional studies have been reported for this variant. This variant has an ambiguous association with the risk of recurrence of clear cell and papillary renal cell cancer (PMID: 28358873, 23219378, 26505625). It has been reported in the ClinVar database (15x benign) and in the LOVD database (3x benign and 1x likely benign). Based on currently available information, variant c.144G>A should be considered a benign variant. -
