Transposition of the Great Arteries, Dextro-Looped, also known as ventriculoarterial discordance with atrioventricular concordance, is related to transposition of the great arteries and isolated congenitally uncorrected transposition of the great arteries. An important gene associated with Transposition of the Great Arteries, Dextro-Looped is MED13L (Mediator Complex Subunit 13L), and among its related pathways/superpathways are Nervous system development and Human Embryonic Stem Cell Pluripotency. Affiliated tissues include heart and brain, and related phenotypes are tachycardia and hypoxemia
