Ethical Considerations in Preimplantation Genetic Testing and Genetic Diagnosis of Neurological Disorders

Preimplantation genetic testing for monogenic disorders (PGT-M) has been implemented in Japan with a revised definition of severity to reduce the risk of having a child with an inherited genetic disorder. However, further discussion is required on its indication within society. The rapid advancements in treatment options for inherited neuromuscular diseases, potentially suitable for PGT-M, underscore the importance of deepening our understanding of available therapies and genetic literacy, along with addressing ethical issues, together with patients and their families without hindering their autonomous decision-making.
