GENETIC DISEASES

Genetic or molecular diseases are inherited disorders. They cannot be cured by drugs nor prevented by the use of vaccines. They arise from mutations of the genetic code within the DNA of our chronomes. Ionizing radiation (x-rays, ultraviolet light, gamma rays), and chemicals as wellas natural selection can give arise to such mutations. Not all mutations are harmful. Some genetic diseases are the result of an attempt by a population to overcome environmental problems. Sickle cell carries are resistant to malaria, for example.

No cures currently exist for molecular diseases. Some can be alleviated by treating symptoms. Gene therapy is currently a promising technique that, however, is only in its infancy.
