Investigating genetic causes of drug-resistant epilepsy in brain tissue

Dissecting mTOR Pathway Mosaicism in FCDII-Harbouring Epileptic Brain and Peripheral Tissue.

Not applicable Interventional King's College Hospital NHS Trust · NCT06053671

This study is testing if certain genetic changes in brain tissue from epilepsy surgery can help us understand and diagnose drug-resistant epilepsy in patients with focal cortical dysplasia.

What this trial studies

This study focuses on patients with focal cortical dysplasia (FCD), a leading cause of drug-resistant epilepsy. It aims to analyze brain tissue removed during epilepsy surgery to identify mutations in the mTOR pathway genes. Additionally, the study will explore whether these mutations can be detected in circulating free DNA from blood samples and nasal swabs. By employing single cell expression profiling, the researchers hope to uncover new genetic targets associated with FCD, ultimately leading to improved diagnostic and screening tools for epilepsy.

Who should consider this trial

Good fit: Ideal candidates include adults and children with a confirmed or suspected diagnosis of Focal Cortical Dysplasia Type IIA/B who are awaiting epilepsy surgery.

Not a fit: Patients with acute or chronic conditions that limit their ability to participate or those who refuse informed consent may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to the identification of new genetic causes of epilepsy, enhancing diagnostic capabilities and treatment options for patients.

How similar studies have performed: While the approach of investigating genetic mutations in epilepsy is gaining traction, this specific study's focus on mTOR pathway mutations in FCD is relatively novel.
