Campomelic dysplasia: an overview of a rare genetic disorder

Abstract

Campomelic dysplasia is a rare and severe genetic condition that is characterized by shortening and bowing of the long bones, abnormal face, multiple congenital anomalies, and ambiguous genitalia. Having conducted a review of the existing literature on this rare genetic disorder, we herein present the most pertinent and essential data on the condition viewed from the clinical perspective. In the majority of cases when the neonate survives the condition, since the underlying cause is more often than not a de novo mutation of the SOX9 gene, there is no increased risk of recurrence. Diagnosis is tentatively made based on skeletal findings during routine prenatal ultrasound; it may subsequently be confirmed via either prenatal or postnatal molecular genetic testing or else radiologic evaluation. In general, the condition is considered to be lethal in the neonatal period, there is no prenatal treatment and pregnancy termination is an option.
