4.4 Ethical considerations in genome editing

Genome editing raises complex ethical concerns and societal implications. From safety issues to equity challenges, this technology's potential impacts are far-reaching. Balancing benefits with risks requires careful consideration of diverse perspectives and ethical frameworks.

Regulations for genome editing vary globally, creating a complex landscape for researchers and policymakers. Personal views on ethical gene editing often involve weighing scientific evidence, societal impacts, and individual values to form policy recommendations and guide responsible use.

1 of 3

• Safety concerns
  • Off-target effects cause unintended mutations in non-target genes
  • Mosaicism results in some cells carrying edited genes while others remain unedited
  • Long-term consequences remain unknown due to limited longitudinal studies
• Informed consent
  • Future generations affected without ability to consent to genetic modifications
• Enhancement vs. therapy debate
  • Defining medical necessity challenges distinction between treatment and enhancement
  • Potential for creating "designer babies" raises concerns about genetic determinism
• Embryo research ethics
  • Moral status of embryos questioned regarding personhood and rights
  • Destruction of embryos during research sparks ethical debates
• Genetic diversity
  • Potential loss of genetic variation in populations reduces adaptability to environmental changes
• Eugenics concerns
  • Historical context of forced sterilization and racial discrimination (Nazi Germany)
  • Potential for misuse in selecting "desirable" traits leads to discrimination

Societal implications of genetic modification

• Equity and access issues
  • Socioeconomic disparities in technology availability widen health gaps
  • Global differences in regulatory frameworks create "genetic tourism"
• Unintended consequences
  • Ecological impacts of gene drive technologies disrupt ecosystems (mosquito population control)
  • Potential for dual-use research raises biosecurity concerns (engineered pathogens)
• Social pressures and discrimination
  • Genetic "haves" and "have-nots" create new forms of inequality
  • Employment and insurance discrimination based on genetic information
• Impact on disability communities
  • Changing perceptions of genetic conditions affect identity and support
• Reproductive decision-making
  • Increased pressure for genetic screening influences family planning choices
• Scientific and medical advancements
  • Potential for curing genetic diseases improves quality of life (sickle cell anemia)
  • Development of new therapies expands treatment options (CAR-T cell therapy)

Regulatory Landscape and Personal Perspectives

Regulations for genome editing research

• International guidelines
  • WHO guidelines on human genome editing promote responsible governance
  • UNESCO Universal Declaration on the Human Genome and Human Rights protects human rights
• National regulations
  • Variations in policies across countries create regulatory patchwork
  • FDA and NIH oversight in the United States ensure safety and ethical compliance
• Clinical trial regulations
  • Somatic vs. germline editing distinctions determine permissible research
• Research oversight
  • Institutional Review Boards (IRBs) evaluate ethical implications of proposed studies
  • Embryo research limitations vary by country and institution
• Moratorium discussions
  • Calls for temporary bans on certain applications (human germline editing)
• Gene therapy regulations
  • Approved therapies and ongoing clinical trials undergo rigorous safety assessments
• International scientific community statements
  • CRISPR pioneers' calls for responsible use shape ethical discourse

Personal perspectives on ethical gene editing
