Variants in the gene SCN1B, encoding the splice variants NaV-β1 and NaV-β1B, are implicated in a variety of inherited pathologies including epileptic encephalopathy (O'Malley and Isom, 2015), Brugada syndrome (BrS) (Watanabe et al., 2008; Hu et al., 2012), long-QT syndrome (LQTS) (Riuró et al., 2014), atrial arrhythmias (Watanabe et al., 2009), and sudden infant death syndrome (SIDS) (Hu et al., 2012) (Figure 1, Table 1). The gene discussed is SCN1B; the disease is sudden infant death syndrome.
