GATA6 mutations have been associated with pancreatic atresia as well as congenital heart malformations, including atrial septal defect, ventricular septal defect, tetralogy of Fallot, pulmonic stenosis, transposition of the great vessels, tricuspid atresia, and double outlet right ventricle (Digilio & Marino, 2016; de Souza, Mergener, Huber, Campos Pellanda, & Riegel, 2015). Here, GATA6 is linked to atrial septal defect.
