Hypopituitarism is a deficiency in one or more trophic hormones, including adrenocorticotropic hormone (ACTH), thyroid-stimulating hormone (TSH), prolactin, growth hormone (GH), and gonadotropins, such as luteinizing hormone (LH) and follicle-stimulating hormone (FSH) [1]. The gene discussed is GH1; the disease is hypopituitarism.
