Powerful Perceptions of Genetic Information

Area of Science:

• Genetics
• Bioethics
• Medical Decision-Making

Background:

• Ethical, Legal, and Social Implications (ELSI) research has focused on genetic testing risks.
• Previous work assumed accurate prediction of health problems from genomic results.
• This study introduces "genetic bias," where uncertain results are overvalued.

Purpose of the Study:

• To define and explore "genetic bias" in genetic testing.
• To examine the impact of genetic bias on clinical decisions, particularly in neonatology.
• To identify potential mitigation strategies for genetic bias.

Main Methods:

• Conceptual analysis of genetic bias.
• Exploration through the lens of neonatology.
• Consideration of preliminary evidence of bias in neonatologists and parents.

Main Results:

• Genetic bias leads to overestimation of genomic result accuracy.
• This overestimation can result in inappropriate clinical decisions and undue limitations in care.
• Preliminary evidence suggests both neonatologists and parents exhibit genetic bias.

Conclusions:

• Genetic bias poses a significant risk in clinical settings, especially neonatology.
• Overly definitive interpretations of uncertain genetic results can negatively impact patient care.
• Addressing genetic bias is crucial for improving the responsible use of genetic testing.
