Hypokalemic periodic paralysis: Case report

Abstract

Hypokalemic periodic paralysis is a disease included in the skeletal muscle channelopathies, characterized by attacks of muscle weakness secondary to dysfunction of Cav1.1 calcium or Nav1.4 sodium channels. We report a case of a patient with a diagnosis of episodic hypokalemic paralysis confirmed by genetic study, and a brief discussion regarding the importance of genetic analysis, its clinical and therapeutic implications.
