Bardet-Biedl syndrome (BBS) is a human genetic disorder associated with ciliary dysfunction, resulting in obesity, retinal degeneration, polydactyly, and nephropathy. Twelve BBS genes (BBS1-12) have been identified. BBS6, BBS10, and BBS12 have sequence homology to the CCT (also known as TRiC) family of group II chaperonins. They form a complex with CCT/TRiC family chaperonins and mediate BBSome assembly [].
