Sciences Dr. Clay Marsh says that although “a lot of good promise” could come
from gene editing, it is mostly practiced in lab models, not in people. A
professor in China announced that he has successfully altered twin girls’ DNA
to prevent them from contracting HIV; however, ethicists and scientists alike
have condemned gene editing in humans. Marsh notes the human body is
complicated and everything is so interconnected that changing one thing can
lead to a cascade of changing everything.

“If a person is born with a particular gene
that makes them at risk for breast cancer or ovarian cancer or other diseases,
scientists may be able to identify that susceptibility and get rid of it. The
big concern, though, is the butterfly effect – little changes can lead to big
outcome differences – and this is editing the basic blueprint of our DNA. This
might lead to other editing effects such as deleting certain genes that protect
you from cancer or cut out a gene set that might reduce your resistance to
infection.”
