A spectrum of complex oligogenic disorders called the ciliopathies have been connected to dysfunction of cilia. Among the ciliopathies are Nephronophthisis (NPHP), characterized by cystic kidney disease and retinal degeneration, and Meckel–Gruber syndrome (MKS), a gestational lethal condition with skeletal abnormalities, cystic kidneys and CNS malformation. Mutations in multiple genes have been identified in NPHP and MKS patients, and an unexpected finding has been that mutations within the same gene can cause either disorder. Further, there is minimal genotype–phenotype correlation and despite recessive inheritance, numerous patients were identified as having a single heterozygous mutation. This has made it difficult to determine the significance of these mutations on disease pathogenesis and led to the hypothesis that clinical presentation in an individual will be determined by genetic interactions between mutations in multiple cilia-related genes. Here we utilize Caenorhabditis elegans and cilia-associated behavioral and morphologic assays to evaluate the pathogenic potential of eight previously reported human NPHP4 missense mutations. We assess the impact of these mutations on C. elegans NPHP-4 function, localization and evaluate potential interactions with mutations in MKS complex genes...
