Register of patients with neonatal-onset epileptic encephalopathy

Creation of a Register of Patients With Neonatal-onset Epileptic Encephalopathy

Assistance Publique Hopitaux De Marseille · NCT04802135

This study is trying to gather information about babies with neonatal-onset epileptic encephalopathy to see how genetic factors, especially changes in the KCNQ2 gene, affect their condition and help improve treatment options.

What this trial studies

This observational study aims to create a register for patients diagnosed with neonatal-onset epileptic encephalopathy (EOEE), a severe condition characterized by early-onset epilepsy and rapid deterioration of cognitive and motor skills. The study focuses on identifying genetic factors, particularly pathogenic variants in the KCNQ2 gene, which are known to play a significant role in this condition. By collecting data through surveys and questionnaires completed by parents, the study seeks to better understand the clinical features and genetic underpinnings of KCNQ2-related epileptic encephalopathy. The findings may help in developing targeted therapies and improving patient management.

Who should consider this trial

Good fit: Ideal candidates include infants diagnosed with epilepsy that begins before one month of age and requires anti-epileptic treatment without identifiable causes.

Not a fit: Patients with neonatal epilepsy due to identifiable causes such as infections or brain malformations may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and management of neonatal-onset epileptic encephalopathy, potentially guiding future treatments.

How similar studies have performed: While the genetic basis of EOEE is being explored, this specific approach to creating a patient register is relatively novel and has not been extensively tested in similar studies.
