CRISPR/Cas9 in the treatment of sickle cell disease (SCD) and its comparison with traditional treatment approaches: a review.

Sickle cell disease (SCD) is a common hereditary blood disorder that profoundly impacts individuals' health, causing chronic pain, anemia, organ damage, increased susceptibility to infections, and social and psychological effects. Over the years, advances in treatment have improved the long-term outcomes of SCD patients. However, problems such as limited access to hematopoietic stem cell transplantation (HSCT) and potential complications associated with the available therapies underscore the importance of continued research and development. The recent FDA approval of Casgevy (Exagamglogene autotemcel), a genetic therapy based on CRISPR/Cas9 technology, demonstrates a comprehensive effort to address the complexity of SCD using new technologies. This review explores the potential of CRISPR/Cas9 for treating SCD and evaluates its efficacy, safety, and long-term outcomes compared to traditional treatment approaches. Long-term research is needed to comprehensively assess the safety, effectiveness, and inclusion of CRISPR/Cas9, ensuring its overall efficacy.
