What is one potential scientific benefit of the human genome project?

Hey. Let me help you on this one.

Human genome project is one of the most prospective medicine projects which are still in progress. It is currently considered as a breakthrough in science, and is quite expensive; however, Kevin Hrusovsky - chief executive of Caliper Life Sciences, says that the prices for genome mapping will drop ten to twenty times lower than they are right now in ten years.

Human genome mapping allows to pinpoint early signs of diseases such as cancer, and allow doctors to have enough time to cure it at it's earliest stage. This significantly increases the chances of survival up to 97%, some sources say. 

As you've just read, one of the benefits of HGP, or human genome project is the fact that it provides a whole new way of treating patients who have diseases that are often deadly. It works because human genome mapping allows doctors to compare genomes of a sick person with genomes of a patient, and pinpoint any early signs of the disease long before any symptoms show up.
