What is the Origin of Idiopathic Short Stature?

The term is derived from the Greek idios (one's own) and pathos (suffering), literally meaning a condition of unknown origin, combined with the descriptive term short stature. Its use reflects the diagnostic limitation when growth failure is present but all known causes have been excluded.

What is the Mechanism of Idiopathic Short Stature?

While the precise mechanism remains elusive, ISS is often hypothesized to involve subtle, complex, and potentially polygenic defects in the growth plate's sensitivity to growth factors, including Growth Hormone (GH) and Insulin-like Growth Factor 1 (IGF-1). These subtle defects may cumulatively dampen the effectiveness of the somatotropic axis, leading to a reduced growth velocity and ultimately a shorter adult height without a clear deficiency in the circulating hormone levels themselves.

Idiopathic Short Stature

Meaning

Idiopathic Short Stature (ISS) is a clinical diagnosis applied to individuals whose height falls significantly below the normal range, typically below the third percentile for age and sex, where a thorough diagnostic workup has failed to identify a specific underlying pathological cause. This means common endocrine disorders, systemic diseases, or definitive genetic syndromes have been ruled out. It represents a significant challenge in pediatric endocrinology due to the lack of a clear, single etiology.
