Bardet-Biedl syndrome is characterised by usually severe pigmentary retinopathy, early-onset obesity, polydactyly, hypogenitalism, renal malformation and mental retardation []. Bardet-Biedl syndrome proteins (BBS1, BBS2, BBS4, BBS5, BBS7, BBS8/TTC8, BBS9 and BBIP10) form the BBSome complex, which may function as a coat complex required for sorting of specific membrane proteins to the primary cilia []. The ciliary trafficking function of BBSome is regulated by LZTFL1 (Leucine-zipper transcription factor-like 1) [].Primary cilia are ubiquitous cellular appendages that provide important sensory and signalling functions and their dysfunction underlies numerous human genetic disorders. The proteins disrupted in the human ciliary disorder Bardet-Biedl syndrome (BBS) are required for the localisation of G protein-coupled receptors to primary cilia on central neurons. The alteration of signalling caused by mislocalisation of ciliary signalling proteins underlies the BBS phenotype []. Of the 12 known BBS genes, BBS1 is the most commonly mutated [].This entry represents BBS1.

Bardet-Biedl syndrome is a member of genetic ciliopathies, but the link between cilia/centrosome deficits and metabolic abnormalities is not completely clear []. Bardet-Biedl syndrome (BBS) is a heterogeneous genetic disorder characterised by many features, including retinal degeneration, obesity, cognitive impairment, polydactyly, renal abnormalities, and hypogenitalism. BBS genes play an important role in maintaining leptin sensitivity in proopiomelanocortin neurons []. A relatively high incidence of BBS is found in the mixed Arab populations of Kuwait and in Bedouin tribes throughout the Middle East, most likely due to the high rate of consaguinity in these populations and a founder effect.Primary cilia are ubiquitous cellular appendages that provide important sensory and signalling functions and their dysfunction underlies numerous human genetic disorders.
