The replication and repair mechanisms of tumour cells are defective, causing an extremely chaotic and messy mutational landscape, where the contribution of most variants to tumour progression cannot be quantified easily. There are some key genes that are known to initiate many different types of cancer, and they have distinct mutational features that are well-known, such as mutational hotspots or highly conserved and delicate residues.
