Summary

Hypokalemia is a frequently encountered electrolyte disturbance, particularly among hospitalized patients. It often arises from increased potassium excretion (via the kidney or gastrointestinal tract) or intracellular shifts [1]. Hypokalemic periodic paralysis (HPP) is an uncommon cause of hypokalemia, with the most common reported mutation found in the dihydropyridine-sensitive calcium channel in skeletal muscles (CACNA1S gene) [2]. We present a case of a young woman with HPP associated with a novel mutation in the chloride voltage-gated channel 1 (CLCN1) gene.
