A
disease is condition that impairs the human body from doing its function. Hundreds
of diseases exit today and each one has its own set of symptoms and signs that
can be diagnose by a physician. Because of theses diseases, many people are
affected and suffer due to no treatment being available. Some of the most
common diseases that are affecting humans today are heart disease, cancer,
Alzheimer’s, diabetes and more. New technologies are now being invented to not
only treat but to actually cure the disease. One in particular is gene therapy.
  This phenomenon has been around for many
years but in recent years it has been talked about more. Gene therapy has many
benefits for a person being treated with this method such as they could be
cured. However, they’re many controversies of this method too that I will be
talking about in this paper.

 

Gene
therapy is the process of inserting genes into an individual’s cells and
tissues to treat a disease/ heredity disease. This is done by, replacing a
defective mutant allele with a functional allele that inactivates the gene that
is not working properly. Although gene therapy is still a working progress, it
has been successful in most studies. A carrier or vector is used to deliver the
gene to the target cell (Thomas et al, 2003). The (Thomas et al, 2003). They
inject the altered virus and once they reach the target tissue or cell, they
infect it. All gene therapy on humans is administered on somatic cells. In
somatic cells there are two categories that gene therapy can be split into: ex
vivo (exterior of the cells) and vivo (inside the cell) (Thomas et al, 2003).

Gene
therapy can be the new medicine for disease. In study done by (Daya and Berns,
2008) they were able to treat haemophila B using rAAV. rAAV is virus that has
the ability to infect both nondividing and dividing cells. Their result showed
that with this virus they were able to cure haemophila B. Another study done by
(Garber, 2006), were able to treat certain cancers using conditionally replicating
oncolytic viruses. By changing the genetic makeup of a human being, there will
be a change in possibility their offspring will carry the disease too.

 

On
the other hand, there are some cons to gene therapy that need to be considered.
One is the ethical approach (Anderson, 1985). Many people who are religious might
not agree with changing ones genetic makeup to cure a disease (Anderson, 1985).
They believe that it’ “playing god” and that it shouldn’t be tampered with.
Another negative to gene therapy, is it may develop a new disease, when genes
are being changed something unexpected could happen that can create a whole new
disease because when one messes with genes a mutation can occur at any moment
(Anderson, 1985).

 

In
conclusion, gene therapy could be the new method on curing diseases.  By changing the genetic makeup of a person,
and removing or deleting the gene that is not working a person can be cured. On
the downside there are some cons that can make a person think twice before committing
themselves to the procedure, such as the ethical view and the chance if
creating a new whole new disease will the healthy genes are being inserted.
