What is the Origin of GHR Gene Polymorphism?

The term combines the abbreviation for the Growth Hormone Receptor gene with polymorphism, a genetics term meaning a common variation in a gene sequence among a population. The clinical relevance of specific GHR polymorphisms was established through studies examining familial short stature and individual responses to exogenous Growth Hormone administration.

What is the Mechanism of GHR Gene Polymorphism?

A specific polymorphism, such as the GHR-d3 allele, involves the deletion of exon 3, which results in a shorter receptor that may exhibit altered signaling properties. This genetic difference can lead to varying degrees of Growth Hormone sensitivity in target tissues like the liver and muscle. The resulting differential production of IGF-1 and other downstream factors dictates the individual's anabolic capacity and overall longevity phenotype.

GHR Gene Polymorphism

Meaning

GHR Gene Polymorphism refers to a naturally occurring variation in the DNA sequence of the Growth Hormone Receptor (GHR) gene, resulting in structural differences in the receptor protein. These variations can alter the efficiency with which the body’s cells bind and respond to circulating Growth Hormone. Such polymorphisms contribute significantly to the individual variability observed in height, body composition, and metabolic response to Growth Hormone-based therapies.
