However, if the family pedigree structure is sufficient and family members are cooperative with the testing process, linkage analysis may be performed to confirm cosegregation of a potential inzipida variant identified by sequence analysis with the diabetes insipida nefrogenica phenotype in individual families.

Expression studies in Xenopus oocytes of the different AQP2 mutated proteins identified in individuals with the autosomal dominant form of NDI showed that all these AQP2 mutated proteins are functional water channels, but on expression in polarized cells, it appeared that all mutants mistargeted to destinations diabetes insipida nefrogenica the cell other than the apical membrane destination of wild-type AQP2.
