Proto-oncogenes are those genes that are involved in cell growth and proliferation, with potential examples including the ATM, FGFR2, FN1, IGF1, MAP3K, MMP7, and RHOC genes, while the CASP8 and LSP1 genes have been reported to possess tumor-suppressive properties in certain types of cancer. This evidence concerns the gene FGFR2 and neoplasm.
