Detailed explanation-1: -In the future, genetic therapies may be used to prevent, treat, or cure certain inherited disorders, such as cystic fibrosis, alpha-1 antitrypsin deficiency, hemophilia, beta thalassemia, and sickle cell disease. They also may be used to treat cancers or infections, including HIV.

Detailed explanation-2: -Gene Therapy is used to treat genetic diseases that are extremely harmful, rare, and life-threatening. The definition of a rare disease is dependent on the number of individuals affected by a disease per total number in a group. A rare disease is one that affects between one in 1000 and one in 200, 000 people.

Detailed explanation-3: -Developing a new therapy-including taking it through the clinical trials necessary for government approval-is very expensive. With a limited number of patients to recover those expenses from, developers may never earn money from treating such rare genetic disorders. And some patients may never be able to afford them.
