Gene therapy, which includes the correction of defective genes, is a significant part of the human genome project. which of these is an application of the technique?

Gene therapy is used in the treatment of Severe combined immuno deficiency.

Explanation:

Gene therapy is one of the the most significant tool of human genome project.Gene therapy is used to rectify the abnormal gene by the replacing the abnormal genes or defective genes or non functional gene with a normal gene that encode the desired cellular protein .

    For example gene therapy is used to to treat severe combined immunodeficiency that is caused by the deficiency or defect in an adenosine deaminase enzyme (that helps in the conversion of adenosine to inosine) which ultimately result in the accumulation of adenosine and the related metabolites inside the cell.
