Biophysical and structural mechanisms of epilepsy-associated mutations in the S4-S5 Linker of KCNQ2 channels.

Abstract excerpt

Mutations in KCNQ2 are linked to various neurological disorders, including neonatal-onset epilepsy. The severity of these conditions often correlates with the mutation's location and the biochemical properties of the altered amino acid side chains. Two mutations affecting aspartate at position 212 (D212) in the S4-S5 linker of KCNQ2 have been identified. Interestingly, while the charge-conserved D212E mutation...
