Three cases in two unrelated consanguineous families with homozygous loss of function variants, with ID as a feature of the phenotype. Multiple null model organisms recapitulate the human phenotype: Null mouse model had cystic kidneys, a phenotype common to ciliopathies. Reducing Cby levels in Xenopus laevis model reduced the density of multiciliated cells, the number of basal bodies per multiciliated cell, and the numbers of neural tube primary cilia; it also led to abnormal development of the neural crest, central nervous system, and pronephros. Depletion of cby1 in zebrafish results in ciliopathy‐related phenotypes.
