Mind the Gap: Acetazolamide Prolonged Periods without Paralysis in a Girl with Andersen-Tawil Syndrome

Abstract

We present a case report of a 13-year-old girl with Andersen-Tawil Syndrome (ATS), a rare genetic disorder which is characterized by dysmorphic features, ventricular arrhythmias, and frequent episodes of muscle paralysis that interfere with daily activities and social engagement. After the introduction of off-label treatment with acetazolamide periods without paralysis lengthened, our patient became more independent of the help of her parents and required a wheelchair less frequently, thus improving her social life. Based on our experience, we recommend a trial of acetazolamide in patients with ATS.
