Channelopathies are a group of diseases caused by the dysfunction of ion channel subunits or their interacting proteins. These diseases can be inherited or acquired by other disorders, drugs, or toxins. Mutations in genes encoding ion channels, which impair channel function, are the most common cause of … See more Genetic type Mutations in genes encoding ion channels, which cause defects in channel function, are the most common cause of channelopathies.

WebOct 28, 2024 · Identifying the etiology of seizures is a primary clinical objective in the management of neonatal seizures. Accurate determination of the cause can lead to etiology-specific therapy. Most neonatal seizures are due to acute provoked causes. However, there is increasing recognition of neonatal-onset epilepsy syndromes. WebVoltage-gated sodium channels (NaV) play an essential role in the generation and propagation of action potential, and malfunction caused by mutations can induce irregular neuronal activity.
