Homeobox expressed in ES cells 1, also known as homeobox protein ANF, is a homeobox protein that in humans is encoded by the HESX1 gene.[1]

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

Mutations in the HESX1 gene are associated with some cases of septo-optic dysplasia[2] or Pickardt-Fahlbusch syndrome.[3]
