Note=Rare variants in GATA6 may be a cause of susceptibility to atrial fibrillation, a common sustained cardiac rhythm disturbance. Atrial fibrillation is characterized by disorganized atrial electrical activity and ineffective atrial contraction promoting blood stasis in the atria and reduces ventricular filling. It can result in palpitations, syncope, thromboembolic stroke, and congestive heart failure.
Conotruncal heart malformations (CTHM) [MIM:217095]: A group of congenital heart defects involving the outflow tracts. Examples include truncus arteriosus communis, double-outlet right ventricle and transposition of great arteries. Truncus arteriosus communis is characterized by a single outflow tract instead of a separate aorta and pulmonary artery. In transposition of the great arteries, the aorta arises from the right ventricle and the pulmonary artery from the left ventricle. In double outlet of the right ventricle, both the pulmonary artery and aorta arise from the right ventricle. Note=The disease is caused by mutations affecting the gene represented in this entry. GATA6 mutations have been found in patients with non-syndromic persistent truncus arteriosus (PubMed:19666519).
Atrial septal defect 9 (ASD9) [MIM:614475]: A congenital heart malformation characterized by incomplete closure of the wall between the atria resulting in blood flow from the left to the right atria. Some patients manifest tricuspid valve disease, pulmonary valve disease, and pulmonary artery hypertension. Note=The disease is caused by mutations affecting the gene represented in this entry.
Tetralogy of Fallot (TOF) [MIM:187500]: A congenital heart anomaly which consists of pulmonary stenosis, ventricular septal defect, dextroposition of the aorta (aorta is on the right side instead of the left) and hypertrophy of the right ventricle. In this condition, blood from both ventricles (oxygen-rich and oxygen-poor) is pumped into the body often causing cyanosis. Note=The disease is caused by mutations affecting the gene represented in this entry.
Atrioventricular septal defect 5 (AVSD5) [MIM:614474]: A congenital heart malformation characterized by a common atrioventricular junction coexisting with deficient atrioventricular septation. The complete form involves underdevelopment of the lower part of the atrial septum and the upper part of the ventricular septum; the valve itself is also shared. A less severe form, known as ostium primum atrial septal defect, is characterized by separate atrioventricular valvar orifices despite a common junction. Note=The disease is caused by mutations affecting the gene represented in this entry.
Pancreatic agenesis and congenital heart defects (PACHD) [MIM:600001]: An autosomal dominant disease characterized by pancreatic severe hypoplasia or agenesis, diabetes mellitus, and congenital heart abnormalities including ventricular septal defect, patent ductus arteriosus, pulmonary artery stenosis, truncus arteriosus and tetralogy of Fallot. Note=The disease is caused by mutations affecting the gene represented in this entry.
Transcriptional activator (PubMed:19666519, PubMed:27756709, PubMed:22750565, PubMed:22824924). Regulates SEMA3C and PLXNA2 (PubMed:19666519). Involved in gene regulation specifically in the gastric epithelium (PubMed:9315713). May regulate genes that protect epithelial cells from bacterial infection (PubMed:16968778). Involved in bone morphogenetic protein (BMP)-mediated cardiac-specific gene expression (By similarity). Binds to BMP response element (BMPRE) DNA sequences within cardiac activating regions (By similarity).
