Identification of genes causing inherited cystic kidney diseases has triggered a major interest for the concept of ciliopathies. Indeed, almost all of the proteins involved in human renal cystic diseases are expressed in the primary cilium complex located in renal epithelial cells. Primary cilia are cellular extensions containing a microtubule-based axoneme covered by a specialized plasma membrane [1]. The basal body of the cilia, which templates the assembly of the microtubules, contains a centriole, which itself is part of the centrosome. Primary cilia project into the lumen, where they probably sense a variety of stimuli involved in the regulation of cell proliferation and differentiation [2]. Primary cilia are present on almost all human cells, explaining why ciliopathies affect multiple organs. However, the molecular mechanisms, potential connections and clinical variability of these diseases remain poorly understood. The study by Delous et al. gives new insights into
