The disease not treated by Ex-vivo gene therapy is:
Correct answer: C. Hypercholesterolemia
- A. SCID
- B. Diabetes
- C. Hypercholesterolemia
- D. All of the above
Explanation
Among the many gene therapy trials, one is for the treatment of familial hypercholesterolemia a condition that develops when liver cells lack a receptor for removing cholesterol from the blood. The high levels of blood cholesterol make the patient subject to fatal heart attacks at a young age. In a newly developed procedure, a small portion of the liver is surgically excised and infected with a retrovirus containing a normal gene for the receptor. Several patients have experienced a lowering of serum cholesterol levels following this procedure
