Genetic epilepsy syndromes without structural brain abnormalities: clinical features and experimental models

Area of Science:

• Neuroscience
• Genetics
• Molecular Biology

Background:

• Epilepsy genetics is crucial for clinical applications and understanding basic mechanisms.
• Ion channel gene mutations are common in epilepsy without structural brain abnormalities.
• Whole exome/genome sequencing reveals genes beyond ion channels involved in epilepsy.
