What are the ethical considerations surrounding genetic testing in minors?

• A. Balancing potential benefits against future autonomy; testing for untreatable adult-onset conditions is generally deferred.
• B. Always test minors if possible.
• C. Never test minors under any circumstance.
• D. Test results are shared with everyone.

Answer: (A)

Ethical decisions about genetic testing in minors hinge on weighing potential immediate benefits against preserving the child’s future autonomy. If a test would reveal information about a condition that won’t affect the child during childhood and has no available treatment or preventive action now, testing can undermine the child’s future right to decide whether to know that information. In such cases, deferring testing respects the child’s evolving autonomy and helps prevent possible psychological harm, stigma, or discrimination from early knowledge of a risk that cannot be acted upon.

There are exceptions when testing can be justified for a child: if the results would directly inform medical management during childhood, enable preventive steps, or reduce risk through early intervention, then testing may be appropriate. Privacy and appropriate disclosure also matter—sharing results broadly or without careful consent isn’t justified, since genetic information is sensitive and personal.

So the best approach is to balance potential benefits with respect for future autonomy, generally deferring testing for untreatable adult-onset conditions while proceeding if there is clear, immediate clinical benefit during childhood.
