GH receptor: Receptor for pituitary gland growth hormone involved in regulating postnatal body growth. On ligand binding, couples to the JAK2/STAT5 pathway. Defects in GHR are a cause of Laron syndrome (LARS). A severe form of growth hormone insensitivity characterized by growth impairment, short stature, dysfunctional growth hormone receptor, and failure to generate insulin-like growth factor I in response to growth hormone. Defects in GHR may be a cause of idiopathic short stature autosomal (ISSA). Short stature is defined by a subnormal rate of growth. Belongs to the type I cytokine receptor family. Type 1 subfamily. 4 isoforms of the human protein are produced by alternative splicing.
