Twenty-four of the 140 potential ciliopathy genes were identified as being direct cilia interactants (Abi2, Ap4e1, Cdc42, Cdk4, Celsr1, Cops7a, Cyba, Dtnbp1, Dync1li1, Ehmt1, Folr1, Herc1, Klhl5, Mapt, Mib2, Myo7a, Prkab1, Ptp4a1, S1pr3, Sik3, Sugp1, Ube2a, Wsb2, and Xbp1) based on STRING protein interaction analysis (Fig. 1b). This evidence concerns the gene PRKAB1 and ciliopathy.
