There is described a vector for treating a ciliopathy such as Bardet-Biedl syndrome, wherein the vector comprises a promoter operably linked to a ciliopathy gene, wherein the vector can provide transduction of the ciliopathy gene into multiple organs, wherein the promoter is a ubiquitous promoter which can provide expression of the ciliopathy gene in the transduced organs, and wherein the ciliopathy gene encodes a functional protein corresponding to the protein that is mutated in the ciliopathy. Also described is the use of the above vector in a method of treating a ciliopathy, the method comprising administering a therapeutically effective amount of the vector to a patient suffering from a ciliopathy.
