GHR Gene

Meaning

The GHR gene, or Growth Hormone Receptor gene, encodes the transmembrane protein that acts as the specific receptor for Growth Hormone (GH) on the surface of target cells throughout the body. This receptor is the critical molecular link that translates the circulating hormonal signal into an intracellular biological response, particularly the production of Insulin-like Growth Factor 1 (IGF-1) in the liver. Genetic variations or mutations within the GHR gene can significantly alter an individual’s sensitivity to growth hormone, leading to conditions like Laron syndrome or influencing overall longevity.
