Beyond the genome: Ethical, social and legal implications of epilepsy genetics

Epilepsy genetics is a rapidly evolving field focused on identifying new epilepsy-related genes, enhancing our understanding of the mechanisms underlying epilepsy, and developing precision medicine approaches for targeted treatments. However, genetic testing raises ethical, legal, and social issues for people with epilepsy and their families. This review summarizes the implications of genetic testing in epilepsy, focusing on the ethical dilemmas, societal impacts, and legal considerations in clinical practice. This manuscript is structured as a narrative review that integrates real-world clinical case vignettes to illustrate how ethical, social, and legal challenges arise in everyday epilepsy genetics practice. Our aim is to synthesize practical ethical considerations for clinicians working in diverse healthcare settings.

We conducted a narrative review of the current literature and integrated illustrative cases to examine the ethical, social, and legal dimensions of epilepsy genetics.

Ethical issues in epilepsy genetic testing include ensuring informed consent, respecting autonomy, protecting confidentiality and privacy, and balancing the interests of individuals, parents, and society, particularly in the case of genetic testing for minors. Informed consent requires that patients fully understand the risks, benefits, and limitations of testing, including its potential health, emotional, and family impacts. Healthcare professionals must inform patients about the implications of genetic test results and potential risks to family members. Clear communication helps patients understand the information, encourages family discussions, and supports informed consent for disclosure. Disclosure of genetic information to family members without patient consent may be justified under certain conditions. Genetic testing for epilepsy can lead to significant social impacts, such as anxiety, stress, and depression. It may also worsen stigma, discrimination, and social isolation already associated with epilepsy. The concept of "courtesy stigma" may arise when epilepsy is perceived as a hereditary condition, leading to stigma extending beyond the affected individual to their family members. Genetic test results could be used to discriminate against individuals in employment or insurance settings. Genetic testing for epilepsy raises ethical concerns grounded in the principle of justice, particularly equitable access to testing, which may subsequently require legal and policy interventions.

While genetic testing for epilepsy offers substantial benefits for improving treatment and enabling early intervention, it also raises significant ethical, legal, and social challenges for individuals with epilepsy and their families. Robust legal and ethical frameworks are essential to protect patient rights and to maximize the benefits of genetic testing while minimizing potential harms. Addressing these emerging issues requires collaboration among policymakers, healthcare professionals, and genetic counsellors. A coordinated policy response-led by professional bodies such as the International League Against Epilepsy (ILAE) and the International Bureau for Epilepsy (IBE), in partnership with national governments and epilepsy associations-is crucial for promoting ethical standards, equitable access, and culturally appropriate practices.
