- ex. sudden allergy to tomatoes (flavr savr^tm)
What causes allegies in GMOs?

The presence of a Bt toxin. Although Bt toxin is approved by FDA it causes allergies in some consumers.
Gene Therapy

Technique in which a corrected version of the gene is delivered to cells containing the defective gene
