FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a central pair protein present in the axonemes of cells with a "9 + 2" organization of microtubules. The encoded protein is required for the proper function of the axoneme. Mutations in the orthologous gene in mice lead to primary ciliary dyskinesia characterized by immotile nasal and tracheal cilia, reduced clearance of nasal mucus, profound respiratory distress, hydrocephalus, and neonatal lethality within twelve hours of birth due to impaired airway mucociliary clearance. Single-nucleotide polymorphisms in this gene are associated with human height and targeted mutations lead to skeletal malformations affecting the limbs in mice, suggesting a role for this gene in skeletal development.

PHENOTYPE: Homozygous null mice exhibit immotile respiratory cilia with axoneme structural defects, impaired mucociliary clearance, respiratory distress, pulmonary edema, disrupted alveolar epithelium, enlarged brain ventricles consistent with evolving hydrocephalus, failure to suckle, and neonatal lethality.
