Often genetic mutations need to be discussed in a dialectical way, they can be bad or good.
1. Genetic mutations can cause malformations or major diseases, for example, if a mutation occurs in the structure of a gene that controls hemoglobin synthesis, it can lead to sickle cell anemia. Mutations may also cause myelodysplasia, trisomy 21, and other disorders.
2. Mutations can also be a good thing, such as an increase in height and athletic ability in a child whose parents are short. Or the patient himself suffers from cancer, in the occurrence of genetic mutations have targeted drugs, can effectively control the disease, is a good thing.
Therefore, gene mutations can be both good and bad, and need to be judged on a case-by-case basis.
