Cornelia de Lange syndrome is a genetic disorder that affects multiple systems. It is characterized by growth delays and psychomotor retardation associated with various anomalies, including hirsutism, facial dysmorphism, cardiac abnormalities, upper-extremity malformations, and gastrointestinal disorders. Early detection and appropriate management of associated disorders are essential for achieving favorable outcomes.
