Germline gene editing and the precautionary principle.

Area of Science:

• Bioethics
• Genetics
• Public Health

Background:

• The precautionary principle guides decisions facing uncertain, severe threats.
• Human germline gene editing presents such a dilemma, particularly concerning future generations.
• Ethical debates surrounding germline modification require careful risk-benefit analysis.

Purpose of the Study:

• To evaluate the applicability of the precautionary principle to human germline gene editing.
• To analyze existing forms of the precautionary principle and their ethical implications.
• To propose a novel 'sufficientarian precautionary principle' for germline interventions.

Main Methods:

• Distinguishing and assessing various forms of the precautionary principle.
• Examining the ethical considerations of human germline modification.
• Developing and presenting the sufficientarian precautionary principle.

Main Results:

• Plausible versions of the precautionary principle support prioritizing the avoidance of threats to future generations.
• No form of the precautionary principle mandates a complete rejection of germline gene editing.
• The sufficientarian precautionary principle may even support the use of germline editing.

Conclusions:

• The precautionary principle does not necessitate an outright ban on human germline gene editing.
• Ethical frameworks, including novel ones like the sufficientarian principle, can guide responsible decision-making.
• Balancing potential benefits against risks to future generations is crucial in germline intervention debates.
