Genetic Testing to Inform Epilepsy Treatment Management From an International Study of Clinical Practice

Area of Science:

• Genetics
• Neurology

Background:

• Epilepsy diagnosis and management can be complex.
• The impact of genetic diagnoses on epilepsy patient care is not well understood.

Purpose of the Study:

• To evaluate the association between genetic diagnoses in epilepsy patients and subsequent clinical management and outcomes.

Main Methods:

• Retrospective cross-sectional study of 418 epilepsy patients undergoing multigene panel testing.
• Analysis of clinical management changes and patient outcomes reported by healthcare professionals.

Main Results:

• Nearly half of patients (49.8%) with a genetic diagnosis experienced clinical management changes, often within 3 months.
• Positive outcomes were reported in 74.9% of patients with available follow-up, including seizure reduction (64.7%).
• Medication adjustments and specialist referrals were common management changes.

Conclusions:

• Genetic testing in epilepsy patients is associated with significant clinical decision-making.
• Genetic diagnoses can lead to improved patient outcomes and tailored management strategies.
