Andersen-Tawil syndrome.
Advances in the understanding of genetic aspects of cardiovascular diseases, together with an increase in the availability of genetic analysis, have resulted in not only increased diagnosis of known inherited conditions, but also the identification of novel syndromes. The combination of potassium-sensitive periodic paralysis, ventricular arrhythmias and dysmorphism, initially described by Andersen and Tawil, represents such a novel condition. We report a case in which genetic analysis led to the diagnosis of Andersen-Tawil syndrome after 15 years of protracted non-invasive and invasive investigations from initial presentation to ultimate diagnosis in a young female. In conclusion, we describe the clinical and genetic features of Andersen-Tawil syndrome and demonstrate the utility of genetic testing in the diagnosis of cardiovascular disease.
