PIP5K1C and ciliopathy: Similarities between the phenotype of one of the Pip5k1c (encoding PIPKIγ) KO models and ciliopathies supports the contention that PIPKIγ is required for ciliogenesis, whereas the two other Pip5k1c KO models reported do not show ciliopathy phenotypes, raising questions on how to interpret these mouse phenotypes [91–93].
