Pubertal boy presenting with mild disproportionate short stature

Area of Science:

• Pediatric Endocrinology
• Genetics
• Skeletal Dysplasias

Background:

• Short stature in children is a common referral concern.
• Growth deceleration from infancy can indicate underlying conditions.
• Family history and anthropometric measurements are crucial for diagnosis.

Purpose of the Study:

• To investigate the cause of short stature and growth deceleration in a 12-year-old boy.
• To evaluate for skeletal abnormalities contributing to disproportionate growth.

Main Methods:

• Clinical examination including anthropometry (height, weight, BMI, arm span/height, sitting height/height ratios).
• Assessment of pubertal stage and testicular volume.
• Radiographic evaluation of bone age and skeletal features (hand X-ray, wrist curvature).

Main Results:

• Patient exhibited significant short stature (height -2.22 SDS) with growth deceleration (growth velocity -2.1 SDS).
• Disproportionate growth noted: shorter legs/forearms, abnormal arm span/height, and sitting height/height ratios.
• Clinical resemblance to father with abnormal wrist curvature; bone age matched chronological age.

Conclusions:

• The patient's presentation is suggestive of a skeletal dysplasia.
• Disproportionate short stature and specific limb measurements are key diagnostic indicators.
• Further genetic evaluation may be warranted to identify the specific condition.
