Why the study?
Electrophysiological evaluation of KCNQ2 mutations is clinically useful for outcome prediction and selecting anti-seizure medications in developmental and epileptic encephalopathy.
Population
Seven patients diagnosed with KCNQ2-DEE and CHO cells transfected with five KCNQ2 pore mutations
Comparison
KCNQ openers vs baseline and wild-type channels
Design
In vitro electrophysiological and clinical characterization study

Supports individualized ASM selection in KCNQ2-DEE; leaves open whether in vitro responses predict clinical outcomes.
KCNQ openers can rescue the loss-of-function electrophysiological phenotypes of KCNQ2 pore mutations in vitro, providing a basis for personalized therapy in DEE patients.
