Аннотация
BACKGROUND: Skeletal dysplasias encompass a group of genetic conditions associated with cartilaginous and bone tissue abnormalities, exhibiting a variable phenotype depending on the involved genes and mechanisms. Differential diagnosis is challenging as there are many skeletal dysplasias with similar phenotypes.
SUMMARY: In this review, we describe the physiology of skeletal development and the classification of skeletal dysplasias, followed by a practical approach to the workup of a child with suspected skeletal dysplasia. Diagnosis requires clinical, laboratory, and radiological evaluation to differentiate potential conditions in the patient. Genotyping has emerged as a confirmatory tool in many cases, enabling personalized treatment through a multidisciplinary approach and assessment of associated comorbidities.
KEY MESSAGES: As skeletal dysplasias often present with short stature, proportionate or disproportionate, the pediatric endocrinologist plays a crucial role in initial investigative and diagnostic guidance. Identifying the critical clinical manifestations, conducting appropriate initial screening tests, and referring for multidisciplinary follow-up contribute to expeditious diagnosis and family support.
