Introduction: Homozygous loss-of-function mutations of the growth hormone receptor (GHR) gene result in GH insensitivity due to a dysfunctional receptor protein. Heterozygous mutations may result in a variable clinical spectrum ranging from normal height to severe short stature. Gain-of-function variants have been reported rarely.Case Report: We hereby report the case of a Russian boy who was referred to our endocrine o...
