Nutrigenomics and ethics interface: direct-to-consumer services and commercial aspects

Area of Science:

• Genetics
• Consumer Health
• Bioethics

Background:

• Direct-to-consumer (DTC) genetic tests, including nutrigenomic services, are increasingly accessible online.
• Consumers gain access to personal genetic data, but understanding its health implications remains challenging.
• Potential health benefits and harms are associated with DTC genetic testing.

Purpose of the Study:

• To review the ethical and regulatory landscape of DTC genetic testing.
• To focus on nutrigenomic tests and their specific challenges.
• To identify and evaluate policy options for regulating DTC genetic tests.

Main Methods:

• Literature review of ethical and regulatory aspects of DTC genetic testing.
• Analysis of current policy responses and their limitations.
• Identification of potential regulatory strategies.

Main Results:

• Existing regulatory approaches for DTC genetic tests are evolving, moving away from a "one-size-fits-all" model.
• Policy options range from prohibitions to enhanced information disclosure.
• Nutrigenomic tests present unique ethical and regulatory considerations.

Conclusions:

• A comprehensive approach focusing on improved transparency is recommended for DTC genetic tests.
• Informed consumer purchasing decisions require clear information on the strengths and limitations of gene-disease associations.
• Enhanced information disclosure can mitigate risks and empower consumers in the DTC genetic testing market.
