Clinical features and management of 16q24.3 microdeletion KBG syndrome: literature review

The clinical phenotype of patients with microdeletion-type KBGS mainly includes characteristic facial features, macrodontia, skeletal deformities, neurological abnormalities, and eye deformities. Cupid's bow lip, protruding ears, and thick eyebrows may be characteristic facial features of Chinese children with KBGS. Genetic testing is required for definitive diagnosis. Treatment primarily relies on multidisciplinary teams providing symptomatic supportive care, with the aim of achieving early diagnosis and treatment to improve patient outcomes.
