Non-acquired combined pituitary hormone deficiency

Definition

A group of rare disorders characterized by multiple pituitary hormone deficiencies, including somatotropin, thyrotropin, lactotropin, corticotropin and gonadotropin deficiencies, due to mutations of pituitary transcription factors involved in pituitary ontogenesis. Clinical presentation varies depending on the type and severity of the deficiencies as well as the age at diagnosis. If left untreated, the main symptoms include short stature, cognitive impairment and delayed puberty.
