The American Society of Human Genetics had declared in 2017 that the basic research on in vitro human genome editing on embryos and gametes should be promoted but that "At this time, given the nature and number of unanswered scientific, ethical, and policy questions, it is inappropriate to perform germline gene editing that culminates in human ...
The study showed that CRISPR/Cas9 is could effectively be used as a gene-editing tool in human 2PN zygotes, which could potentially lead to a viable pregnancy. The researchers used injection of Cas9 protein complexed with the relevant sgRNAs and homology donors into human embryos.
Concerns have been raised that off-target effects (editing of genes besides the ones intended) may confound the results of a CRISPR gene editing experiment (i.e. the observed phenotypic change may not be due to modifying the target gene, but some other gene). Modifications to CRISPR have been made to minimize the possibility of off-target effects.
These gene drives were originally engineered in January 2015 by Ethan Bier and Valentino Gantz; this editing was spurred by the discovery of CRISPR-Cas9. In late 2015, DARPA started to study approaches that could halt gene drives if they went out of control and threatened biological species.
Ethical considerations regarding gene editing are largely controversial within the scientific community due to its open ended implications for the rest of society. [19] Although no consensus has been reached, there are plans in place to utilize the available resources to continue education, scientific research as well as research on ethical ...

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.
Here's the story behind the biotech stock that could be the best way to profit from the discovery of the century: CRISPR-Cas9 gene editing.
