The same method was subsequently used to unravel the functional modules associated with nine ciliopathy-associated bait proteins, NPHP1–NPHP6, NPHP8, AHI1 and MKS1, identified in the ciliopathies nephronophthisis (NPH), Joubert syndrome (JBTS) and Meckel–Gruber syndrome (MKS) (see Glossary). The gene discussed is AHI1; the disease is Joubert syndrome.
