Doctors are investigating a treatment for an inherited disorder. A working gene is added to some of a patient’s body cells.
The treatment was tested on 80 patients. At the one-year assessment, 52 patients had cells producing the useful protein coded for by the working gene. The other 28 patients did not have cells producing the protein.
Evaluate the use of this genetic treatment for inherited disorders.
