Homeobox protein HESX1

The HESX1 gene encodes a transcription factor involved in the development of forebrain and pituitary gland. Mutations in this gene cause autosomal recessive and dominant with variable penetrance septooptic dysplasia also called growth hormone deficiency with pituitary abnormalities.
