"Heritable human genome editing should not be used unless, at a minimum, it meets reasonable standards for safety and efficacy, is legally sanctioned, and has been developed and tested under a system of rigorous oversight that is subject to responsible governance. At this time, these conditions have not been met.".
How ethical is gene editing in humans?

What are the bioethical concerns of Crispr?
Germline gene therapy raises difficult ethical questions related to tampering with human nature, enhancing human traits, parental control over children, discrimination, social justice and eugenics..
What are the bioethical concerns of Crispr?
Here we review fundamental ethical issues including the following: 1) the extent to which CRISPR use should be permitted; 2) access to CRISPR applications; 3) whether a regulatory framework(s) for clinical research involving human subjects might accommodate all types of human genome editing, including editing of the .
What are the bioethical issues of gene therapy?
In addition to the issues of direct intentional editing of the germ line, other ethical considerations concerning germ line editing include the goal of the intervention: disease curative or “genetic enhancement” and whether the change will re-create what is naturally found in human genetics or whether it will create a .
What are the bioethical issues of gene therapy?
It is a common fear that genetic modification may result in unintended consequences, such as the creation of new allergens or toxins, the spread of modified genes to wild relatives, or the development of antibiotic-resistant bacteria..
What are the ethical issues of gene editing?
The ethical questions surrounding gene therapy and genome editing include:
How can “good” and “bad” uses of these technologies be distinguished?Who decides which traits are normal and which constitute a disability or disorder?Will the high costs of gene therapy make it available only to the wealthy?.

What are the ethical issues with Crispr?
With the rapid application of CRISPR/Cas in clinical research, it is important to consider the ethical implications of such advances. Pertinent issues include accessibility and cost, the need for controlled clinical trials with adequate review, and policies for compassionate use..
When did the idea of gene editing start?
The idea of using gene editing to treat disease or alter traits dates to at least the 1950s and the discovery of the double-helix structure of DNA..
Why is CRISPR a bioethical issue?
CRISPR might also increase the likelihood that genetic mutations will occur. There is potential for new diseases to be released, and whole species, or ecosystems, may be placed in jeopardy. The ecological effects of genetic modification could be catastrophic..

Ethical Concerns Beauchamp and Childress describe the four core ethical principles of bioethics as autonomy, beneficence, non-maleficence and justice. These are key principles that should be considered when thinking about the ethical issues associated with germline editing.
Gene editing allows us to modify our genes. This can cure diseases. But it could also be used in the future to select for traits that give social or competitive advantages. Professor Nicol asked a citizens' jury to decide under what circumstances we should allow human gene editing.

Bioethicists and researchers generally believe that human genome editing for reproductive purposes should not be attempted at this time, but that studies that would make gene therapy safe and effective should continue.
From a philosophical and theological standpoint, therapeutic human genome editing was generally ethically acceptable. Worldwide public perspectives were also in agreement except for the Oceanic region, which disagreed mainly due to the possible effects on future generations.
Some of the ethical dilemmas of genome editing in the germline arise from the fact that changes in the genome can be transferred to the next generations. Therapeutic genome editing in somatic cells generally does not cause significant concerns when assessing the risk/benefit balance and the use of informed consent.
Therefore, therapeutic somatic gene editing is ethically acceptable. However, although gene editing for enhancement purposes brings up ethical questions, it does not threaten human nature, and therefore requires further discussion.
Can germline genome editing be bioethical?
The first of the bioethical issues of successful germline genome editing is the use for nontherapeutic changes (Lanphier et al., 2015; Greely, 2019). Such uses will lead to new questions about breeding (eugenics) of the human species and its position in the universe (Yang, 2015).
Does genetic engineering have a role in bioethics?
For this purpose, reference is made to discussions on genetic engineering that have taken place in the field of bioethics since the 1980s. Our analysis shows that the dominance of categorical arguments has been reversed in favour of pragmatic arguments such as:
safety concerns.
How does gene editing work?
The three main techniques for gene editing involve molecules that recognize and bind to specific DNA sequences; researchers can use custom molecules to affect genetic and epigenetic changes on essentially any gene.
Is human genome editing ethical?
Professors at the University’s schools of medicine, law, business, and government saw He’s announcement as a turning point in the discussion about heritable gene therapies and shared their perspectives on the future of this technology with the Gazette. Aside from the safety risks, human genome editing poses some hefty ethical questions.
Bioethics of gene editing
Way to propagate genes throughout a population
A gene drive is a natural process and technology of genetic engineering that propagates a particular suite of genes throughout a population by altering the probability that a specific allele will be transmitted to offspring. Gene drives can arise through a variety of mechanisms. They have been proposed to provide an effective means of genetically modifying specific populations and entire species.
Gene targeting is a biotechnological tool used to change the
Genetic technique that uses homologous recombination to change an endogenous gene
Gene targeting is a biotechnological tool used to change the DNA sequence of an organism. It is based on the natural DNA-repair mechanism of Homology Directed Repair (HDR), including Homologous Recombination. Gene targeting can be used to make a range of sizes of DNA edits, from larger DNA edits such as inserting entire new genes into an organism, through to much smaller changes to the existing DNA such as a single base-pair change. Gene targeting relies on the presence of a repair template to introduce the user-defined edits to the DNA. The user will design the repair template to contain the desired edit, flanked by DNA sequence corresponding (homologous) to the region of DNA that the user wants to edit; hence the edit is targeted to a particular genomic region. In this way Gene Targeting is distinct from natural homology-directed repair, during which the ‘natural’ DNA repair template of the sister chromatid is used to repair broken DNA. The alteration of DNA sequence in an organism can be useful in both a research context – for example to understand the biological role of a gene – and in biotechnology, for example to alter the traits of an organism.
