Bardet-Biedl syndrome (BBS) is a multisystemic genetic disorder, which is not widespread among the Caucasian population, characterized by a highly variable phenotype and great genetic heterogeneity. BBS belongs to a group of diseases called ciliopathies, caused by defects in the structure and/or function of cilia. Due to the diagnostic complexity of the syndrome, the objective of this study was to analyse our whole group of patients in order to create an algorithm to facilitate the routine molecular diagnosis of BBS. We also calculated several epidemiological parameters in our cohort.
