How De Novo Mutations in HCN1 Cause Early Infantile Epileptic Encephalopathy
De novo mutations in the HCN1 gene change how neurons work. These changes mess with the way ions flow, which is key for stable brain activity. This makes the brain more likely to have too much activity, leading to seizures.
HCN1 De Novo Mutations Link to Infant Epilepsy Early infantile epileptic encephalopathy starts with severe seizures soon after birth. The HCN1 mutations mess with how ions move in and out of neurons. This makes neurons more likely to fire off too much, causing seizures and slow growth.
Studies show that HCN1 mutations change how neurons work. They make neurons stay too active for too long. This can lead to epilepsy, where a normal brain starts having seizures.
| Aspect | HCN1 Mutation Impact | Clinical Manifestations |
|---|---|---|
| Molecular Mechanisms | Altered ion channel permeability | Frequent seizures |
| Electrophysiological Alterations | Prolonged neuronal depolarization | Epileptogenesis |
| Neurological Condition | Hyperexcitability of neural network | Developmental delays |
Understanding how HCN1 mutations affect the brain is key to treating early infantile epileptic encephalopathy. More research is needed to find new ways to help those affected.
