Abstract:

The Bardet-Biedl syndrome (BBS) is a rare autosomal recessive disorder affecting multiple systems, primarily manifesting as retinal lesions, polydactylism (or hyperdactylism), obesity, intellectual diminution, sexual duct development deficiency, and renal abnormalities. To date, 26 disease-causing genes have been identified, all of which are localised to the primary cilia, with the BBS1, BBS2 and BBS10 genes being the most common genetic causes. There is no curative therapy for this disease, and symptomatic supportive treatment is the main focus. This paper reviews the disease from the perspectives of clinical characteristics, diagnostic criteria, causative genes, the current situation of BBS patients in China, and treatment, with a view to providing reference for the clinical diagnosis and treatment of this disease.

Key words: Bardet Biedl syndrome, diagnostic criteria, pathogenic gene, management
