Ventricular Septal Defect 1, also known as vsd1, is related to heart septal defect and ventricular septal defect. An important gene associated with Ventricular Septal Defect 1 is GATA4 (GATA Binding Protein 4), and among its related pathways/superpathways are Mesenchymal Stem Cells and Lineage-specific Markers and Endoderm differentiation. Affiliated tissues include fetal brain and heart, and related phenotypes are atrial septal defect and pulmonic stenosis
