Bardet-Biedl syndrome (BBS) is a rare autosomal recessive disorder with genetic heterogeneity characterized by defects in multiple organ systems. The main features are retinal degeneration, obesity, hypogonadism, polydactyly, renal dysfunction, and mental retardation. BBS is typified by clinical variability observed both within and between families, which can be explained in part by the presence of second-site modifiers. Recent findings in genetic research have suggested that the BBS phenotype is largely associated with ciliary dysfunction.
