MET is frequently overexpressed in glioblastomas (GBM), and some gliomas show hepatocyte growth factor (HGF) autocrine activation of the MET signaling pathway. Several studies have found that HGF and MET are expressed at higher levels in human gliomas than in control brain tissue, and that expression levels correlate with tumor grade. Some studies have shown that the HGF expression in high-grade (WHO Grade III--IV) tumors was significantly higher than in low-grade (WHO I--II) tumors. Similarly, coexpression of HGF and MET is observed more frequently in Grade IV GBM than in low-grade glioma, consistent with the contribution of an HGF/MET autocrine loop to malignant progression in these tumors. However, MET sequence alterations have been rare. The MET M362T variant is classified as a benign/likely benign germline variant in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/93565/). These results should be interpreted in the clinical context.
