Type | disruption phenotype | Description | Mice lack motile respiratory tract cilia and exhibit randomization of the left-right body axis due to loss of motile cilia in the embryonic node (PubMed:9739041, PubMed:10873152). Motile type cilia with a '9 + 2' microtubule ultrastructure are absent in epithelial cells, including those in the airways (PubMed:10873152). |
