UK’s Approval of Gene-Editing License Research
Science & Technology › Biotechnology – Applications · Topic 11.27
In February 2016 the Human Fertilisation and Embryology Authority of the United Kingdom gave the first licence in the world to a scientist, Kathy Niakan of the Francis Crick Institute, to use the CRISPR-Cas9 gene editing tool on human embryos for research. The licence allows study of the genes that control early development, to understand infertility and miscarriage, but forbids implanting the edited embryos in a woman, and the embryos may be kept only up to 14 days. The decision followed the Human Fertilisation and Embryology Act, 1990. The United Kingdom also passed the Genetic Technology Precision Breeding Act, 2023, which eases rules for gene edited plants and animals.

Where Does It Fit?
This topic follows the ragi genome. It shifts from crop genomes to the most sensitive use of gene editing, research on human embryos, and the way the United Kingdom regulates it. Previous topic: Genome Sequencing of Ragi (First in the World). Next topic: Genetically Modified Mosquito for Vector Control.
What Did the United Kingdom Permit and Prohibit?
| Aspect | Details |
|---|---|
| Regulator | The Human Fertilisation and Embryology Authority, a statutory body that licences fertility clinics and embryo research |
| Licence holder | Kathy Niakan, Francis Crick Institute, London |
| Date | Approved on 1 February 2016 |
| Permitted use | Basic research using CRISPR-Cas9 on surplus human embryos donated from fertility treatment, to study early development |
| Prohibited use | Placing an edited embryo in a woman, which is illegal in the United Kingdom |
| Time limit | Embryos must be destroyed by day 14, when the primitive streak appears |
| Consent | Embryos come from donors who gave informed consent |
Why Is the Decision Important and Debated?
- Scientific aim: to learn which genes are needed for a healthy embryo and why many pregnancies fail
- Infertility and miscarriage: knowledge from such work could improve fertility treatment
- Slippery slope concern: critics fear that research will lead to designer babies
- Safety: off target effects and mosaicism, where only some cells are edited, mean that clinical use is not safe now
- Germline edits are heritable: changes pass to future generations, who cannot consent
- International views: the Oviedo Convention of the Council of Europe bans heritable human genome modification, while some countries have no clear law
- Scientific bodies: international summits, including in 2015, 2018 and 2023, said clinical germline editing is not yet acceptable
- After 2018: the birth of gene edited babies in China caused a strong reaction and tighter control, as in Gene Editing (CRISPR) and Gene Therapy
What Else Should You Remember?
- Human Fertilisation and Embryology Act, 1990: the law that created the Authority and allows regulated embryo research up to 14 days
- Primitive streak: the first sign of the body axis in an embryo, around day 14, used as the limit in many countries
- Revisiting the limit: some scientists have asked to extend the 14-day rule, and the debate continues
- Mitochondrial donation: the United Kingdom also legalised mitochondrial replacement in 2015, as in Designer Babies/Three-Parent Babies
- Precision Breeding Act: the Genetic Technology (Precision Breeding) Act of 2023 allows gene edited plants and animals that could have arisen naturally to be treated differently from GM organisms in England
- Plants first: rules for gene edited food plants in England started in 2025, with animals to follow later, so check the latest status
- India: Indian rules prohibit germline editing of embryos in clinical use, as in the guidelines of the Indian Council of Medical Research
- Contrast with the United States: the United States bars its regulator from reviewing applications for clinical use of edited embryos, and has limits on federal funding for embryo research
- China: introduced rules after 2018 that require ethics approval for gene editing in humans
- Responsible innovation: licensing, ethics review and public consultation are used to balance research and risk
- Public dialogue: surveys in the United Kingdom found support for editing to prevent serious disease but not for enhancement
- Exam angle: a common question asks the difference between research on embryos, which can be licensed, and implantation, which is banned
- Embryo sources: research embryos come from IVF cycles where couples donate those they do not need, with consent and approval from the Authority
- Public interest: the Authority consults the public before major decisions on embryo research
Why Does It Matter for the Exam?
- Facts: HFEA, 2016, 14 days
- Distinction: research versus implantation
- Related laws: UK Act 1990, Precision Breeding Act 2023
- Current affairs link: heritable editing debates
- Common errors: saying that the UK allowed edited babies to be born
As an analytical point, licensed research is a way to gain knowledge under supervision. Clear lines against implantation and enhancement, with international coordination, keep research useful and safe.
Why Is This Topic Important?
- Law HFEA licence
- Limits 14 days, no implantation
- Ethics Germline debate

Frequently Asked Questions
What did the United Kingdom approve in 2016?
In February 2016 the Human Fertilisation and Embryology Authority licensed Kathy Niakan at the Francis Crick Institute to use CRISPR-Cas9 gene editing on human embryos for research. It was the first such approval in the world, and it allows the study of early development but does not allow the embryos to be implanted.
What is the 14-day rule?
The 14-day rule limits research on human embryos made outside the body to the first 14 days of development, or until the primitive streak appears, whichever comes first. It is part of the United Kingdom law of 1990 and has been followed in many countries, though some scientists have asked for it to be reviewed.
Is it legal to create gene edited babies in the United Kingdom?
No. In the United Kingdom, gene editing of embryos is allowed only for licensed research, and an edited embryo cannot be implanted into a woman. Implantation of such embryos would be a criminal offence under the Human Fertilisation and Embryology Act, as heritable editing is considered unsafe and ethically unresolved.
What is germline gene editing?
Germline gene editing changes the DNA of eggs, sperm or embryos, so that the change is inherited by all later generations. Because the effects are permanent, the risks of off target edits are unknown and future generations cannot give consent, most countries ban or tightly restrict its use in humans.
What is the Precision Breeding Act, 2023?
The Genetic Technology Precision Breeding Act, 2023 is a United Kingdom law that creates a lighter regulatory path for plants and animals produced by gene editing, if the changes could have been obtained by traditional breeding or natural processes. It applies in England and does not cover organisms with foreign DNA.
PYQ Practice — Statement Analysis
1 The UK licence of 2016 allowed gene edited embryos to be implanted in women.
Only research use was allowed.
2 The 14-day rule limits the time human embryos may be kept for research.
Until the primitive streak appears.
3 The regulator that gave the 2016 licence is the HFEA.
A UK statutory authority.
4 Germline editing changes are inherited by future generations.
Which is why it is restricted.
