Which kind of therapy was given in 1990 to a four year girl with Adenosine Deaminase (ADA) enzyme deficiency?
Correct answer: A. Gene therapy
- A. Gene therapy
- B. Chemotherapy
- C. Immunotherapy
- D. Radiation therapy
Explanation
Gene therapy is a technique of genetic engineering which involves the replacement of a faulty/disease-causing gene by a normal healthy functional gene. The first clinical ex-vivo gene therapy was given in 1990 to a 4-year old girl with adenosine deaminase (ADA) enzyme deficiency. This enzyme is very important for the immune system to function and the deficiency of this enzyme can lead to severe combined immune deficiency (SCID).
