Mutation can result in many different types of change in sequences. Mutations in genes can either have no effect, alter the product of a gene, or prevent the gene from functioning properly or completely. Mutations can also occur in nongenic regions.
DNA Repair Genes. When it comes to cancer and how things can go wrong in the cell cycle, three different genes are very important: 1  An oncogene is a proto-oncogene that has been mutated.2  Proto-oncogenes stimulate the cell to grow, divide and move through each cell cycle checkpoint to be inspected.his is like pushing down on the gas pedal-you now have a gene that is telling the cell, go, go, go; don't pay attention to the checkpoint and stop. Not all genes can mutate and form oncogenes. Only proto-oncogenes can mutate to form an oncogene. There are about 70 proto-oncogenes in our DNA.
