Genetically engineered cells are introduced into bone marrow cells in the treatment of:
Correct answer: B. Severe Combined Immunodeficiency Syndrome (SCID)
- A. Hypercholesterolemia
- B. Severe Combined Immunodeficiency Syndrome (SCID)
- C. Cystic Fibrosis
- D. Coronary Artery Angioplasty
Explanation
Gene therapy for SCID involves the removal of bone marrow stem cells from the patient. These cells are injected with the with a retrovirus which carries the normal gene into the cells. The stem cells are returned to the patient, and they start producing the needed enzyme.
