What is the Origin of GHR Polymorphism?

This term originates from the field of molecular genetics and endocrinology, combining the specific target, "Growth Hormone Receptor," with the genetic concept of "Polymorphism," which means "many forms." The identification of these variations is a result of advanced genomic sequencing.

What is the Mechanism of GHR Polymorphism?

A notable example is the GHR exon 3 deletion polymorphism, which results in a shorter receptor isoform. This structural change can influence the efficiency of GH binding and the subsequent downstream intracellular signaling cascade, particularly the JAK-STAT pathway that leads to the production of IGF-1. The presence of a specific polymorphism can therefore determine the magnitude of the anabolic and metabolic effects elicited by a given concentration of Growth Hormone.

GHR Polymorphism

Meaning

GHR Polymorphism refers to the occurrence of common genetic variations, or alleles, within the gene that encodes the Growth Hormone Receptor (GHR). These specific sequence differences can subtly alter the structure or expression of the receptor protein, thereby affecting the body’s sensitivity and response to circulating Growth Hormone (GH). Clinically, these variations are studied to predict individual differences in growth, metabolism, and response to GH therapy.
