What type of diseases was gene therapy first used for?

Following 18 years of further research, the first gene therapy trial launched in 1990. A four-year-old girl named Ashanthi DeSilva underwent a 12-day treatment for a rare genetic disease known as severe combined immunodeficiency.

What are the side effects of gene therapy?

After initially receiving a type of gene therapy, the patient’s immune system may react to the foreign vector. Symptoms of a reaction may include fever, severe chills (called rigors), drop in blood pressure, nausea, vomiting, and headache. These symptoms typically resolve within 24-48 hours of the infusion.

Is gene therapy a permanent cure?

Gene therapy offers the possibility of a permanent cure for any of the more than 10,000 human diseases caused by a defect in a single gene. Among these diseases, the hemophilias represent an ideal target, and studies in both animals and humans have provided evidence that a permanent cure for hemophilia is within reach.

What are the 2 types of gene therapy?

There are two types of gene therapy treatment: Somatic cell gene therapy and germline therapy. Somatic cell gene therapy involves obtaining blood cells from a person with a genetic disease and then introducing a normal gene into the defective cell (Coutts, 1998).

What are the disadvantages of gene therapy?

Potential Disadvantages of Gene Therapy Gene therapy poses a number of risks. The way the genes are delivered and the different vectors may present the following risks. DNA mutations The new gene might be inserted in the wrong location in the DNA, which might cause harmful mutations to the DNA or even cancer.
