Background: Bardet Biedl syndrome(BBS) is a type of non-motile ciliopathy primarily characterized by retinal dystrophy, obesity, polydactyly, cognitive impairment, urogenital anomalies and renal abnormalities. To date, 26 genes have been reported to be associated with BBS: BBS1-BBS21, IFT74, SCLT1, SCAPER and NPHP1. BBS is genetically heterogeneous with significant clinical overlap with other ciliopathies, further c...
