A novel SNAP25 gene variant causes developmental and epileptic encephalopathy (DEE) in a child, presenting with seizures and episodic ataxia. This finding expands the known genetic causes of DEE.
Area of Science:
- Neurogenetics
- Developmental Neuroscience
- Epileptology
Background:
- Developmental and epileptic encephalopathies (DEEs) are severe early-onset neurological disorders.
- Synaptosomal-associated protein 25 (SNAP25) gene variants are known causes of DEEs.
- SNAP25 is crucial for the presynaptic SNARE complex, essential for neurotransmitter release.

Seizures: Classification
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
