In addition, sequence variations in the splicing sites and coding regions of GATA6 have also been reported in other cardiovascular diseases such as dilated cardiomyopathy (DCM) (van Berlo et al., 2010; Xu et al., 2014) and cardiac conduction system (CCS) including atrial fibrillation (AF) (Li et al., 2012; Yang et al., 2012; Liu et al., 2015; Nemer and Gharibeh, 2015; Tucker et al., 2017). The gene discussed is GATA6; the disease is atrial fibrillation.
