Defining the Critical Components of Informed Consent for Genetic Testing

Area of Science:

• Genetics
• Bioethics
• Medical Counseling

Background:

• Informed consent for genetic testing lacks standardized core concepts.
• Current practices often occur during pretest genetic counseling without specific guidance.

Purpose of the Study:

• To identify essential core concepts for informed consent in clinical genetic testing.
• Establish a foundation for quality patient care in genetic testing.

Main Methods:

• Expert consensus process by the ClinGen Consent and Disclosure Recommendations Workgroup (CADRe).
• Literature review of 77 concepts related to genetic testing informed consent.
• Two-round survey of 25 experts (medical geneticists, genetic counselors, bioethicists) ranking concept importance.

Main Results:

• Key concepts include test voluntariness, purpose, scope, result types, and implications.
• Prognosis, management impact, family impact, test limitations, and next steps are crucial.
• Potential for genetic discrimination and available legal protections must be addressed.

Conclusions:

• Defining core concepts for genetic testing informed consent is vital.
• Standardized concepts enhance patient understanding and quality of care.
• Provides a framework for diverse healthcare providers and clinical settings.
