Understanding the genetics of Juvenile Myoclonic Epilepsy

Biology of Juvenile Myoclonic Epilepsy

Observational King's College London · NCT03400371

This study is trying to find the genetic causes of Juvenile Myoclonic Epilepsy by collecting blood samples and health information from people with the condition and comparing it to data from those without epilepsy.

What this trial studies

This observational study aims to collect genetic information and clinical data from over 1000 individuals diagnosed with Juvenile Myoclonic Epilepsy (JME) across the UK, Europe, and North America. Participants will provide blood samples and allow access to their clinical EEG data, which will be compared to anonymized data from 2000 control subjects without epilepsy. The primary goal is to identify the genetic causes of JME, which could lead to improved treatments and earlier detection of the condition.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 10-40 years with a diagnosis of Juvenile Myoclonic Epilepsy and specific EEG characteristics.

Not a fit: Patients with myoclonus only associated with certain medications or those with other forms of epilepsy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better treatments and improved outcomes for patients with Juvenile Myoclonic Epilepsy.

How similar studies have performed: Other studies have shown success in identifying genetic causes of epilepsy, suggesting that this approach may yield valuable insights.
