Use of preimplantation genetic testing for monogenic defects (PGT-M) for adult-onset conditions: an Ethics Committee opinion.

Preimplantation genetic testing for monogenic diseases for adult-onset conditions is ethically permissible for a range of conditions including when the condition is serious and no safe, effective interventions are available. The Committee strongly recommends that a genetic counselor experienced with PGT-M counsel patients considering such procedures.
