| description | any anomaly in the migratory path of cardiac neural crest cells (NCCs), a subpopulation of cranial NCCs which originate from the lower hindbrain between the otic placode and third somite and migrate to the circumpharyngeal ridge (an arc-shape ridge located dorsal to the forming caudal pharyngeal arches) and then into the 3rd, 4th and 6th pharyngeal arches and the cardiac outflow tract (OFT); cardiac NCCs undergo migration away from the neural tube by following a dorsolateral path under the ectoderm, leading them to the pharyngeal arches; after pausing, they resume migration under the pharyngeal endoderm and, along the aortic arch arteries, populate the cardiac OFT where they contribute the aorticopulmonary septum, and ultimately colonize the heart to form the ventricular septum and cardiac ganglia |
