About this study

The aims of study on KCNQ2-related epilepsy: (1) establish phenotype database and sample database of KCNQ2-related epilepsy; (2) to establish genotype-phenotype association of KCNQ2-related epilepsy; (3) to study the brain network of KCNQ2-related epilepsy based on multi-modal brain image and EEG data; (4) to find prognostic biomarkers of KCNQ2-related epilepsy based on omics study.

Read the detailed description
  1. Participant recruitment: participants are recruited from Chinese KCNQ2-related epilepsy patients group (http://www.kcnq2.cn/). According to the clinical phenotype, the participants will be divided into benign familial neonatal seizures (BFNS) group and Developmental and epileptic encephalopathy (DEE) group.
  2. Genotype-phenotype association: electrophysiological detection of KCNQ2 mutation will be performed using patch clamp technique in an in vitro cell model. The association between phenotype (such as epileptic phenotype, developmental assessment and drug response) and genotype will be analyzed.
  3. Brain network analysis: participants who provide informed consent will be scaned by brain magnetic resonance imaging (MRI) or positron emission tomography-computed tomography (PET-CT) and monitored by the electroencephalogram (EEG). The Brain Network of KCNQ2-related epilepsy will be analyzed based on multi-modal brain image and EEG between BFNS and DEE group.
  4. Omics Study: after informed consent, blood, urine and feces samples of participants will be taken. The samples were tested for omics study including proteomics, metabolomics, transcriptomics, to analysis the difference of BFNS and DEE group.

Questions about this trial

What is this clinical trial studying?

An observational study of KCNQ2-related Epilepsy, run by Fudan University at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 15 Dec 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Yi Wang, Dr (13564766228, yiwang@shmu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Establish the phenotype database and genotype-phenotype association of KCNQ2-related Epilepsy (time frame: 0-18 years old). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Dec 2021.
