CRISPR Gene Editing to Designer Babies- For Good or a Weapon of Mass Manipulation?

This short write-up explores the science behind gene editing technologies and their ethical implications. Discusses how these advancements are being regulated and received by society.

Introduction

CRISPR gene editing is changing biotechnology with futuristic tools like CRISPR-Cas9-which enables precise modifications of DNA. It holds promise for advancing medicine and genetics. At the same time, also raises significant questions regarding bioethics in genetics.

As we keep advancing the science with these ground-breaking innovations, we need to address the moral considerations accompanying them as well.

CRISPR-Cas9 (Clustered Regularly Interspaced Short Palindromic Repeats) technology allows to make targeted changes to DNA. CRISPR technology works with the Cas9 enzyme (occurs naturally as a defense system in bacteria where it helps defend against viruses by slashing their DNAs).

Cas9 enzyme is used to slit DNA at specific locations with remarkable precision. Thereby it helps to correct genetic mutations that cause genetic diseases or to study gene functions.

CRISPR Gene Editing Application Areas

o?? Animal models

o?? Genome editing in specific tissues

o?? Multiple gene mutations

o?? Epigenome studies

o?? Treatment of diseases

o?? Industrial uses

o?? RNA editing

o?? Military applications (for increasing the tolerance of soldiers against biological

o?? or chemical wars).

o?? DNA replacement in human embryos (the most controversial use)

Simply put, ?CRISPR technology is a powerful, cost effective & popular tool in both research and therapeutic applications. However, it raises difficult questions on *bioethics in genetics; the most alarming is perhaps the use of CRISPR-Cas9 to germline genome editing.

Germline genome editing brings the most complex gene editing ethics dilemmas; particularly when it comes to creating "Designer Babies" that is, selecting or modifying traits in embryos-such as physical appearance or intelligence.

Ethical Implications of Gene Editing

? Critics argue that it could lead to social inequalities as the expensive genetic enhancements would remain accessible mostly to the wealthy.

They also express concerns about the long-term consequences of such modifications on future generations and the human gene pool. While the proponents on the other hand emphasize its positive side- that it could eliminate genetic disorders and improve quality of life.

For a deeper understanding of the ethical considerations surrounding gene editing, we spoke with Dr. Emily Carter- director of the Center for Bioethics at Harvard Medical School (HMS) ?

Interviewer: "Dr. Carter, with CRISPR and similar technologies advancing rapidly, what are the primary ethical concerns you see?"

Dr. Carter: "The ethical concerns surrounding CRISPR technology are multifaceted. One major issue is the potential of worsening genetic inequality. If gene editing becomes accessible primarily to the wealthy, it could create a society where genetic enhancements are reserved for those with the means to afford them. Besides, it comes with the risk of unintended consequences. Editing the human genome, especially the embryonic genes, could have unknown effects on future generations. It is important therefore that we approach with caution and ensure that the benefits of this technology are equitably distributed."

Interviewer: "What about the concept of designer babies? How does this fit into the ethical debate?"

Dr. Carter: "The idea of designer babies, that is, selecting or altering traits in embryos raises many ethical questions. And serious ones. Agreed, the ability to prevent genetic diseases is a positive aspect, but the potential for creating genetically enriched humans introduces new ethical dilemmas. It could lead to a new form of genetic discrimination or accelerate social divides. We need to carefully consider the long-term implications and establish robust ethical guidelines to ensure that gene editing is used responsibly and does not lead to unintended harm."

While it is understood that gene editing needs regulations considering the probable outcomes, the regulation approach varies globally. ?

In the United States, for example, the Food and Drug Administration (FDA) regulates gene editing research, but does not have a comprehensive guideline for editing human embryos.

Whereas, the European Union has stricter regulations for germline modifications. China (post its gene-edited baby scandal) has regulations prohibiting human embryonic gene editing but its enforcement calls for monitoring.

India has strict guidelines to use gene editing only for researches and not for clinical or reproductive use.

To sum up, gene editing and technologies like CRISPR-Cas9 offer incredible opportunities but come with serious challenges and bioethical issues.

The scientist community and other interested and related stakeholders like social, legal, bioethical parties and government need to develop a comprehensive guideline for future use and advancement of this technology.

Long term policies and solutions need to be framed after discussion among all the concerned collaborating communities across the countries of the globe.
