can genetic diseases be cured
In a family with sickle-cell anemia and PKU, each child has a 25 percent risk of inheriting. No genetic illness can be cured. Hemophiliacs can inject clotting factors, and people with PKU can adjust their diet, but they can never get rid of their genes. The best way to deal with genetic disorders is to prevent them through screening. Simple blood tests can detect the gene for sickle-cell anemia.
