Polygenic risk scores and embryonic screening: considerations for regulation

Area of Science:

• Reproductive genetics
• Bioethics
• Genetic screening

Background:

• Polygenic risk scores (PRSs) are increasingly discussed for use in reproductive decision-making.
• Their application in embryonic screening presents novel ethical and regulatory challenges.
• Current use is limited but growing, necessitating careful consideration.

Purpose of the Study:

• To provide an overview of the ethical considerations associated with using PRSs in embryo screening.
• To propose regulatory considerations for jurisdictions considering the use of PRSs in reproductive contexts.
• To address the need for ongoing technological and research refinement.

Main Methods:

• Ethical analysis of PRS application in reproductive genetics.
• Review of potential regulatory frameworks for genetic screening technologies.
• Identification of key components for future regulation.

Main Results:

• Significant ethical considerations arise from using PRSs for embryo screening.
• A comprehensive regulatory framework is necessary for responsible implementation.
• Key regulatory elements include clear eligibility, education, and oversight.

Conclusions:

• The use of PRSs in embryo screening requires careful ethical deliberation and robust regulatory oversight.
• Future regulations must address technological advancements, public education, and ongoing consultation.
• Proactive regulatory planning is essential for navigating the complexities of PRS in reproductive decision-making.
