Predictive genetic testing of children and the role of the best interest standard

Area of Science:

• Pediatric Healthcare Ethics
• Genetic Testing Law
• Comparative Bioethics

Background:

• The "best interest standard" is a cornerstone of pediatric healthcare in both the United States (US) and the United Kingdom (UK).
• Divergent legal and ethical frameworks exist for intervening in parental decision-making in pediatric care between the US and UK.
• The US typically requires a finding of abuse or neglect for intervention, while the UK may permit intervention for non-ideal parental decisions.

Purpose of the Study:

• To analyze the influence of differing applications of the "best interest standard" on the practice of predictive genetic testing in children.
• To compare how variations in the "best interest standard" in the US and UK affect genetic testing protocols for minors.
• To explore the ethical and legal implications of distinct intervention principles in pediatric healthcare on genetic testing decisions.

Main Methods:

• Comparative legal and ethical analysis of pediatric healthcare policies in the US and UK.
• Examination of case law and legislative frameworks related to parental rights and child welfare in genetic testing contexts.
• Review of ethical guidelines and professional recommendations for predictive genetic testing in minors.

Main Results:

• The US approach, requiring a higher threshold for intervention, may lead to different patterns in the uptake and oversight of predictive genetic testing for children compared to the UK.
• The UK's broader application of the "best interest standard" for parental decision-making could facilitate or alter the landscape of predictive genetic testing in pediatric settings.
• Discrepancies in intervention principles create distinct environments for the ethical and legal implementation of pediatric genetic testing.

Conclusions:

• The differing interpretations and applications of the "best interest standard" significantly shape the context for predictive genetic testing in children across the US and UK.
• Understanding these jurisdictional differences is crucial for developing globally consistent yet locally relevant ethical guidelines for pediatric genetic testing.
• Future research should investigate the real-world impact of these divergent standards on families undergoing predictive genetic testing for their children.
