Graphic illustration of the difference between QTc among mutation carriers (KCNQ1, KCNH2 and SCN5A ) compared with index cases in which no mutation was identified. The figure shows a significant QTc difference between LQTS mutation carriers and index cases without an identified mutation (KCNQ1 (n= 41) versus genotype-negative (n=61) p= 0.0001, KCNH2 (n=20) versus genotype-negative p=0.01, SCN5A (n=10) versus genotype-negative p=0.005). The scatter dot plot show QTc mean and SD.
