The First CRISPR Gene Therapy Is Here

The video discusses the use of CRISPR, a gene-editing tool, in treating sickle cell disease. It highlights the approval of Casgevi, a CRISPR-based therapy, and Lyfgenia, a viral vector-based therapy, both aimed at curing sickle cell disease. The video explains the challenges of living with sickle cell, the treatment process, and the impact of these therapies. It also addresses the high costs and limited accessibility of these treatments, emphasizing the potential of CRISPR in future medical applications.

What is the primary application of CRISPR technology as discussed in the video?

• Creating new species

• Editing plant genes for better yield

• Modifying animal behavior

• Treating blood disorders

Which of the following is NOT a symptom of sickle cell disease?

• High blood pressure

• Anemia

• Fever

• Vaso-occlusive crises

What is the main advantage of Casgevi in treating sickle cell disease?

• It uses traditional bone marrow transplant methods

• It requires no medical supervision

• It reactivates fetal hemoglobin

• It is a dietary supplement

Which gene editing tool is used in Casgevi?

• RNA interference

• TALENs

• Zinc finger nucleases

• CRISPR-Cas9

What is the role of fetal hemoglobin in Casgevi treatment?

• It is replaced by adult hemoglobin

• It is silenced permanently

• It is removed from the DNA

• It is reactivated to carry oxygen

How does Lyfgenia differ from Casgevi in its approach to gene editing?

• It involves dietary changes

• It uses CRISPR technology

• It is a surgical procedure

• It uses lentiviral vectors

What was a significant risk identified during the clinical trials of Lyfgenia?

• Increased risk of diabetes

• Development of acute myeloid leukemia

• Severe allergic reactions

• Loss of vision

What is a major barrier to accessing treatments like Casgevi and Lyfgenia?

• Lack of trained doctors

• Complex dietary requirements

• High cost of treatment

• Unavailability of hospitals

What is the estimated cost of Casgevi treatment?

• $4 million

• $1 million

• $3.1 million

• $2.2 million

What is a common requirement for both Casgevi and Lyfgenia treatments?

• Dietary supplements

• Daily medication

• Chemotherapy

• Surgical intervention
