WebIf a parent carries a gene mutation in their egg or sperm, it can pass to their child. These hereditary (or inherited) mutations are in almost every cell of the person's body throughout their life. Hereditary mutations include cystic fibrosis, hemophilia, and sickle cell disease. Other mutations can happen on their own during a person's life. WebGenetic mutations usually take place after birth and aren't inherited. A number of factors can lead to gene mutations, including smoking, radiation, viruses, chemicals that cause cancer (carcinogens), hormones, obesity, lack of exercise and chronic inflammation. It is common for genes to mutate during normal cell growth.
