Expectedly concentrations of some pituitary hormones or hormones released by their target peripheral glands were lower in patients with hypopituitarism (and also in patients with other pituitary diseases or in all patients with pituitary diseases) than in control individuals and these differences relate to ACTH, LH, FSH (of borderline significance), TSH and, regarding peripheral hormones, to cortisol and FT3. Here, PLOD1 is linked to hypopituitarism.
