HESX1

{{Short description|Protein-coding gene in the species Homo sapiens}}

{{Infobox_gene}}

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.{{cite web | title = Entrez Gene: HESX homeobox 1| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=8820}}

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{{cite journal |vauthors=Dattani MT, Martinez-Barbera JP, Thomas PQ, etal |title=Mutations in the homeobox gene HESX1/Hesx1 associated with septo-optic dysplasia in human and mouse |journal=Nat.
