The advent of CRISPR-Cas9 gene editing technology has led to the possibility of creating "designer babies." This technology has the possibility of eliminating certain genetic diseases, or improving health by enhancing certain genetic traits.
Victoria Gray was the first patient ever to be treated with the gene-editing tool CRISPR for sickle-cell disease. [1]This marked the initial indication that a cure is attainable for individuals born with sickle-cell disease and another severe blood disorder, beta-thalassemia.
CRISPR gene editing is a revolutionary technology that allows for precise, targeted modifications to the DNA of living organisms. Developed from a natural defense mechanism found in bacteria, CRISPR-Cas9 is the most commonly used system, that allows "cutting" of DNA at specific locations and either delete, modify, or insert genetic material.
Until now, the only known cure for sickle cell disease was a bone marrow transplant from a donor, which carries the risk of rejection by the immune system, in addition to the difficult process of ...
CRISPR technology is a promising tool not only for genetic disease corrections but also for the prevention of viral and bacterial infections. Utilizing CRISPR–Cas therapies, researchers have targeted viral infections like HSV-1, EBV, HIV-1, HBV, HPV, and HCV, with ongoing clinical trials for an HIV-clearing strategy named EBT-101 ...
Modifying human embryos to give the CCR5 Δ32 allele protects them from the disease. An other use would be to cure genetic disorders. In the first study published regarding human germline engineering, the researchers attempted to edit the HBB gene which codes for the human β-globin protein. HBB mutations produce β-thalassaemia, which can be ...
Engineered gene drives using CRISPR-cas9 are currently being tested and have been proposed as strategies to eliminate invasive species and disease vectors. By genetically modifying an organism to express an endogenous sequence-specific endonuclease, a target (such as a fertility gene) can be cleaved on the opposite chromosome. [64]
Unlike traditional CRISPR-Cas9, which introduces double-strand breaks to edit genes, CRISPRa employs a modified, catalytically inactive Cas9 (dCas9) fused with transcriptional activators to target promoter or enhancer regions, thereby boosting gene transcription. This method allows for precise control of gene expression, making it a valuable ...
