Insights
Idiopathic short stature (ISS) and growth hormone deficiency (GHD) are common causes of short stature in children. Genetic testing is recommended for severe cases after ruling out GHD for accurate diagnosis.
Area of Science:
- Pediatrics
- Genetics
- Endocrinology
Background:
- Short stature in children is a significant clinical concern.
- Understanding the underlying causes is crucial for effective management.
Purpose of the Study:
- To investigate the etiological factors and genetic diagnosis in children presenting with short stature.
- To analyze the clinical features associated with different causes of short stature.
Main Methods:
- Retrospective analysis of 86 children with short stature.
- Evaluation of etiological distribution and clinical characteristics.
- Comparison of clinical and biochemical parameters between groups.
Main Results:
- Idiopathic short stature (41%) and growth hormone deficiency (29%) were the most frequent causes.
- Genetic diseases accounted for 14% of cases.
- Genetic disease group showed more severe height deficits compared to ISS, but not GHD.
Conclusions:
- Idiopathic short stature, growth hormone deficiency, and genetic diseases are primary contributors to short stature in children.
- Genetic testing is advised for severe short stature cases post-GHD exclusion.
- Clinical manifestations of genetic short stature exhibit heterogeneity and overlap.
Objective:
To study the etiology and genetic diagnosis of children with short stature.
Methods:
A retrospective analysis was performed to study the etiological distribution and clinical features of 86 children with short stature.
Results:
A total of 6 causes were observed in these children, among which idiopathic short stature (ISS, 41%) and growth hormone deficiency (GHD, 29%) were the most common causes, followed by genetic diseases (14%). There were no significant differences in age at the time of diagnosis, body height, body length and weight at birth, body height of parents and insulin-like growth factor-1 levels between the genetic disease group and the ISS/GHD groups (P>0.05). Compared with the ISS group, the genetic disease group had significantly lower deviation from the 3rd percentile for the height of children of the same age and sex (ΔP3) and height standard deviation score (P<0.05), while there were no significant differences between the genetic disease and GHD groups (P>0.05). The analysis of the clinical manifestations for the genetic disease group showed heterogeneity and phenotypic overlap in children with different genetic diseases.
Conclusions:
ISS, GHD and genetic diseases are major causes of short stature in children. For children with severe short stature, genetic testing should be performed to make a definitive diagnosis after GHD has been excluded.
