Description	Long QT syndrome (LQTS) is a hereditary arrhythmic syndrome characterized by abnormal prolongation of QT interval, increased risk of malignant ventricular arrhythmias and sudden death. With the prevalence 1:2000 it is the most often diagnosed arrhythmogenic disorder. At least 15 LQTS-related genes have been identified so far, nevertheless 75% of mutations are found in 3 major genes (KCNQ1, KCNH2 and SCN5A). Here we report identification of likely pathogenic variants in patient previously investigated with negative results.
