[Current status and implication of research on Bardet-Biedl syndrome].

Bardet-Biedl syndrome (BBS) is a rare autosomal recessive disease initially reported by Bardet and Biedl in the 1920s. BBS is a pleiotropic and genetically heterogeneous disorder characterized by retinopathy, obesity, polydactyly, renal malformations and functional abnormalities, learning disabilities and hypogenitalism. BBS patients are also prone to diabetes mellitus, hypertension and congenital heart disease. To date, 16 BBS genes (BBS1-BBS16) have been identified. However, the molecular etiology of BBS is not yet entirely clear. In this article, we have reviewed recent research on BBS and discussed its implications for understanding of ciliopathology.
