Because GHD (growth hormone deficiency) and Alström Syndrome share some clinical and metabolic features, we studied the GH-IGF1 axis, using MRI techniques, dynamic tests (insulin tolerance test, ITT), MPHD (multiple pituitary hormone deficiency), and the metabolic disturbances related to GHD in this adolescent girl with Alström Syndrome. Here, IGF1 is linked to Alstrom syndrome.
