Expression of HEX1 and HESX1 marks the anterior visceral endoderm of the embryo. The AVE is an extra-embryonic tissue, key to the establishment of the anterior-posterior body axis.

Clinical significance

edit

Mutations in the HESX1 gene are associated with some cases of septo-optic dysplasia[6] or Pickardt-Fahlbusch syndrome.[7]
