When is genetic testing of children for adult-onset disorders a consideration?[Scroll to bottom for answer]
Performing predictive or predispositional genetic testing in children for a disease with adult-onset is generally discouraged. To preserve autonomy and minimize potential harm to the child, testing is often deferred unless there are medical implications in childhood. However, guidelines are not clear cut and recognize that psychological benefits are important to consider, particularly if the child can provide assent. Pre- and post-test genetic counseling is crucial.
