Insights
Human growth assessment is crucial for health. Evaluating short stature (SS) involves auxological parameters and understanding genetic factors, with therapeutic options available.
Area of Science:
- Pediatrics
- Endocrinology
- Genetics
Background:
- Human growth is a dynamic health indicator, influenced by genetics, hormones, nutrition, and environment.
- Short stature (SS) evaluation lacks international consensus, complicating diagnosis and management.
- Auxological parameters are key for assessing SS, whether diagnosed or idiopathic.
Purpose of the Study:
- To outline the complexities in evaluating short stature (SS) in children.
- To discuss the genetic underpinnings and classification of SS.
- To present an algorithm for SS evaluation and available therapeutic options.
Main Methods:
- Review of auxological parameters for assessing growth in children.
- Analysis of monogenic diseases and genetic skeletal disorders associated with SS.
- Discussion of diagnostic algorithms and treatment strategies for SS.
Main Results:
- Numerous monogenic diseases causing proportionate SS have been identified, linked to growth hormone and IGF pathways.
- The Nosology and Classification of Genetic Skeletal Disorders encompasses 436 conditions.
- Diagnostic and therapeutic approaches for SS are evolving.
Conclusions:
- Accurate assessment of human growth is vital for identifying potential health issues like short stature.
- Understanding the genetic basis of SS is crucial for diagnosis and targeted therapies.
- A structured approach to evaluating SS, incorporating genetic insights, aids in management.
Abstract:
Human growth, from fetal life to adolescence, is dynamic and a good marker of health. Growth is a complex process influenced by genetic, hormonal, nutritional and environmental factors, both pre- and postnatally. To date, no international agreement regarding normal height has been established. Auxological parameters are fundamental to investigate potential short stature (SS), either with a known diagnosis, e.g. disproportionate or proportionate, prenatal and/or postnatal onset, or an unknown diagnosis, i.e. idiopathic SS. The incidence/prevalence of SS is difficult to establish. The measurement of choice in children aged <2 years is length, while in those >2 years of age it is height. A number of monogenic diseases that lead to proportionate SS due to either isolated growth hormone deficiency, multiple pituitary hormone deficiency, growth hormone insensitivity, primary acid-labile subunit deficiency, primary IGF-1 deficiency, IGF-1 resistance, primary IGF-2 deficiency or primary protease deficiency have been discovered in the last 30 years. In addition, the Nosology and Classification of Genetic Skeletal Disorders revised in 2015 includes 436 conditions, with a number of genes of 364. A practical algorithm for the evaluation of SS as well as therapeutic options are discussed.
