000 genes, scientists know the function of very few. Once the human genome sequence is complete, scientists will focus on researching the functions of genes. The third hurdle are the multigene disorders. Most genetic disorders involve more than one gene. Most diseases also involve the interaction of the environment. Many people who develop cancer not only inherit the gene for the disorder, but also may smoke to contribute to the disease.With technology advancing, it is not out of the question to understand and fully develop successful gene therapy techniques. Currently, scientists are working on a cure for Cystic Fibrosis. It may sound ridiculous, but scientists in Philadelphia have combined pieces from two of the worlds deadliest microbes, the Ebola virus and the virus that causes AIDS, to make a hybrid virus they hope will someday cure Cystic Fibrosis. The goal is to make a virus with Ebolas unusual talent for attaching to lung cells and the AIDS viruss exceptional ability to persist in the body, then use the new virus to deliver curative genes to patients with lung disease. The approach is safe because scientists only use pieces of the two viruss and eliminate the genes that would kill someone.As technology improves it is safe to say that scientists will figure out all the complications that interfere in successful gene therapy treatments. In the future their may be a cure for all known diseases using the application of somatic gene therapy....
