Gene therapy has been touted as one of the most promising therapies for healthcare in the 21st century. At present, gene therapy is primarily limited by
A) the dynamic nature of the human genome.
B) objections to gene therapy that are posed by religious groups.
C) the difficulty in producing safe, consistent therapeutic results.
D) the fact that only around a dozen known human diseases have a genetic basis.
Ans: C
Although gene therapy is a promising treatment option for a number of diseases
(including inherited disorders, some types of cancer, and certain viral infections), the technique
remains risky and is still under study to ensure its safety and effectiveness. The human genome
is essentially consistent between individuals. Hundreds of diseases have a genetic basis and
opposition from organized groups has not been the primary brake on the development of gene
therapy.
