Gene Therapy for Monogenic Inherited Disorders

Area of Science:

• Biotechnology
• Genetics
• Medical Science

Background:

• Gene therapy presents novel treatment avenues for rare congenital disorders and specific cancers.
• Addresses conditions with previously limited therapeutic options.

Purpose of the Study:

• To review the principles, current clinical status, and methodologies of gene therapy.
• To discuss the outcomes of various gene therapy approaches.

Main Methods:

• Literature review on gene therapy principles, applications, and outcomes.
• Discussion of in vivo and ex vivo gene therapy techniques.

Main Results:

• In vivo gene therapy utilizes adeno-associated viral vectors for genetic correction.
• Ex vivo gene therapy employs lentiviral vectors for cell modification.
• Approved therapies exist for ADA-SCID, RPE65 retinal dystrophy, beta-thalassemia, and spinal muscular atrophy.
• Early-administered gene therapy for spinal muscular atrophy shows remarkable motor development gains.

Conclusions:

• First gene therapies are approved, offering potential long-term benefits from single administration.
• Challenges include generating evidence, defining indications, treatment delivery, and pricing for rare disease therapies.
