The developmental basis of these congenital anomalies is poorly understood, but recent genome sequencing reveals that\n                  <jats:italic>de novo<\/jats:italic>\n                  variants in intracellular trafficking genes are enriched in EA\/TEF patients.

We show that the Rab11a recycling endosome pathway is required to localize Vangl-Celsr polarity complexes at the luminal cell surface where opposite sides of the foregut tube fuse. Partial loss of endosome trafficking or Vangl-Celsr complexes disrupts epithelial polarity and mutant cells accumulate at the fusion point, fail to downregulate Cadherin, and do not separate into distinct trachea and esophagus. These data provide insights into the mechanisms of congenital anomalies and general paradigms of tissue fusion during organogenesis.\n
