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]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PM1

In a region_of_interest Interaction with RANBP9 (size 178) in uniprot entity MET_HUMAN there are 8 pathogenic changes around while only 1 benign (89%) in NM_000245.4

BP4

Computational evidence support a benign effect (MetaRNN=0.08791885).

BS1

Variant frequency is greater than expected in population mid. gnomad4_exome allele frequency = 0.0000123 (18/1461820) while in subpopulation MID AF= 0.000173 (1/5768). AF 95% confidence interval is 0.0000298. There are 0 homozygotes in gnomad4_exome. There are 9 alleles in male gnomad4_exome subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 1400 of the MET protein (p.Arg1400Gln). This variant is present in population databases (rs752694306, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with MET-related conditions. ClinVar contains an entry for this variant (Variation ID: 220057). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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. -
