Congenital multiple pituitary hormone deficiency including somatotroph, thyrotroph, lactotroph, corticotroph or gonadotroph deficiencies, due to mutations of pituitary transcription factors involved in pituitary ontogenesis. Rare when compared with the high incidence of hypopituitarism induced by pituitary adenomas, transsphenoidal surgery or radiotherapy. Clinical presentation is variable, depending on the type and severity of deficiencies and on the age at diagnosis. If untreated, main symptoms include short stature, cognitive alterations or delayed puberty. Due to mutations of several genes encoding pituitary transcription factors. A diagnosis must be suspected when evident causes of hypopituitarism have been ruled out. Type of transmission varies with the factor and the mutation involved.
