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]

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]

ACMG classification

Our verdict: Benign. The variant received -17 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.75).
• BP6: Variant 7-116699096-C-T is Benign according to our data. Variant chr7-116699096-C-T is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 358682.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP7: Synonymous conserved (PhyloP=-0.611 with no splicing effect.
• BS1: Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.0000525 (8/152248) while in subpopulation EAS AF = 0.000386 (2/5180). AF 95% confidence interval is 0.0000683. There are 0 homozygotes in GnomAd4. There are 5 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
