This study focuses on the characterization of mutations in the voltage-gated potassium channel KV2.1, identified in two children with an epileptic phenotype who did not respond to conventional treatments. Epilepsy, defined by the WHO as a chronic brain disorder characterized by recurrent seizures, affects around 50 million people worldwide, significantly impacting quality of life and creating socioeconomic burdens. The specific mutations discovered (W369C and V413I) in these patients underscore the need to better understand their effect on KV2.1 function. This research examines these mutations by expressing and analyzing the mutant proteins in transfected HEK293 cells, comparing their electrophysiological properties to those of the wild-type variant using the patch-clamp technique and immunocytochemistry assays. The findings reveal a significant reduction in the generated currents and a notably lower expression of the mutant channels. This progress lays the groundwork for the development of targeted therapies that could enhance the quality of life for patients with epileptic encephalopathies.
