This type of mutation is known as a miscense mutation. So this is shown in the diagram above. And one very common example of a point mutation known as a Nissan Mutation is sickle cell anemia, in which the hemoglobin that is formed is basically not as active as it should be. So a Nissan Mutation may or may not lead to problems. And an example where it does lead to problems is in sickle cell anemia. So sickle cell anemia is an example of a miscensed mutation that alters the structure of our hemoglobin.
