The MET gene encodes a member of the receptor tyrosine kinase (RTK) family of proteins, and, since the early 1980s, different authors have studied the effect of MET on cancer development, starting by Cooper et al., who were the pioneers in recognizing MET gene as a “driver gene” when this concept did not exist yet, describing it as a transforming gene detected in chemically transformed cells [2]. The gene discussed is MET; the disease is cancer.
