What is the Origin of GH Resistance?

The term describes a specific endocrine pathology, drawing a parallel to the more common condition of insulin resistance. The most severe, congenital form, Laron Syndrome, was pivotal in elucidating the underlying molecular defects of the GH signaling pathway. Understanding GH resistance is critical for the differential diagnosis of growth failure and for guiding appropriate therapeutic strategies.

What is the Mechanism of GH Resistance?

Resistance primarily occurs due to defects in the Growth Hormone Receptor (GHR) or subsequent post-receptor signaling pathways, often caused by genetic mutations. When GH fails to bind or activate the GHR on liver cells, the critical Janus kinase 2 (JAK2) and Signal Transducer and Activator of Transcription 5b (STAT5b) cascade is impaired. This failure prevents the liver from synthesizing and secreting IGF-1, leading to the clinical presentation of GH resistance, as the downstream effector molecule is absent.

GH Resistance

Meaning

GH Resistance, or Growth Hormone Resistance, is a state of clinical unresponsiveness of peripheral tissues to the biological actions of circulating Growth Hormone (GH), despite the presence of normal or elevated GH levels. This resistance typically results in a profound deficiency of Insulin-like Growth Factor-1 (IGF-1), which is the primary mediator of GH’s anabolic and growth-promoting effects. The condition impairs linear growth in children and contributes to various metabolic disturbances in adults.
