Originally part of microbial immune systems, it has been adapted for genetic manipulation. The DNA is cut at specific locations, allowing genes to be added or replaced. Unlike previous techniques, CRISPR is faster, cheaper and more accurate with applications in disease treatment, immunity enhancement and even human enhancement. However, clinical applications remain in early stages, focused on animal models and isolated human cells.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/www.yourgenome.org\/theme\/what-is-crispr-cas9\/\"><img loading=\"lazy\" decoding=\"async\" width=\"3000\" height=\"449\" src=\"https:\/\/generic.wordpress.soton.ac.uk\/uosm2031-2025\/wp-content\/uploads\/sites\/529\/2025\/03\/Picture-1-3000x449.png\" alt=\"\" class=\"wp-image-13030\" srcset=\"https:\/\/generic.wordpress.soton.ac.uk\/uosm2031-2025\/wp-content\/uploads\/sites\/529\/2025\/03\/Picture-1-3000x449.png 3000w, https:\/\/generic.wordpress.soton.ac.uk\/uosm2031-2025\/wp-content\/uploads\/sites\/529\/2025\/03\/Picture-1-300x45.png 300w, https:\/\/generic.wordpress.soton.ac.uk\/uosm2031-2025\/wp-content\/uploads\/sites\/529\/2025\/03\/Picture-1-768x115.png 768w, https:\/\/generic.wordpress.soton.ac.uk\/uosm2031-2025\/wp-content\/uploads\/sites\/529\/2025\/03\/Picture-1-1536x230.png 1536w, https:\/\/generic.wordpress.soton.ac.uk\/uosm2031-2025\/wp-content\/uploads\/sites\/529\/2025\/03\/Picture-1-2048x306.png 2048w\" sizes=\"auto, (max-width: 3000px) 100vw, 3000px\" \/><\/a><\/figure>\n\n\n\n<p><\/p>\n\n\n\n<p>As some with a family history of genetic conditions, I find hope in CRISPR&#8217;s early success in treating diseases like Sickle Cell Anaemia.

His experiment targeted the CCR5 gene, which also plays a role in immunity against West Nile virus and severe flu.

Critics warn of unknown long-term effects, unintended consequences and regulatory challenges. Most diseases are multigenic, but CRISPR-Cas9 targets single genes, limiting its effectiveness. Ethical concerns revolve around the potential of human enhancement, inequality and whether parents can truly consent to risks. Even He Jiankui admitted <a href=\"https:\/\/www.theguardian.com\/science\/2017\/jan\/08\/designer-babies-ethical-horror-waiting-to-happen\">designer babies<\/a> would be difficult to control.<\/p>\n\n\n\n<p>Despite concerns, I support scientific progress. Why allow suffering if we have technology to prevent it? Eliminating genetic diseases would ease demand on healthcare and benefit society. Regulation, not rejection, is the key &#8211; gene editing is here and we must adapt to its evolving role in medicine. Balancing innovation with ethics will determine its future.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Looking ahead<\/h2>\n\n\n\n<p>Somatic gene editing is legal in many countries and holds promise for treating disease. However, germline editing remains controversial. As some nations ease restrictions, we may see a global divide in human genetics.<\/p>\n\n\n\n<p>While I believe gene editing has a guaranteed future and remarkable benefits, I worry that without proper regulation, we will face a societal divide. One group will be enhanced, tailored for specific roles with predetermined superhuman qualities, from intelligence to athletic prowess. The other group will be us, free to make our own choices but facing a constant struggle to survive, and subject to natural selection.<\/p>\n\n\n\n<p>Gene editing could revolutionise medicine, but how we choose to use it will determine whether it leads to progress or division.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">References<\/h3>\n\n\n<p>[<a href=\"https:\/\/www.nature.com\/articles\/nprot.2013.143#rightslink\">1<\/a>] Ran FA, Hsu PD, Wright J, Agarwala V, Scott DA, Zhang F.
