One patient with a primary ciliopathy phenotype of cranioectodermal dysplasia arising from mutations in the IFT-A gene WDR35/IFT121 was also reported to have motile ciliopathy symptoms of neonatal respiratory distress, recurrent respiratory infections, sparse and dyskinetic motile cilia, and situs inversus (74). Here, WDR35 is linked to cranioectodermal dysplasia.
