Eustachian Tube Growth and Development: Anatomy/Function. Protocol Description. This study measures Eustachian tube function and facial growth over time in three groups of children: one with recurrent ear infections, one with chronic middle ear fluid, and one with little past history of otitis media.
Causes of Kartagener syndrome. Kartagener syndrome is caused by a mutation in the DNAI1 gene, which makes a cellular protein required for normal functioning cilia (cilia line the respiratory tract) and sperm motility.
Primary ciliary dyskinesia (PCD), also immotile ciliary syndrome or Kartagener syndrome, is a rare, ciliopathic, autosomal recessive genetic disorder that causes defects in the action of cilia lining the respiratory tract (lower and upper, sinuses, Eustachian tube, middle ear) and fallopian tube, as well as in the flagella of sperm cells.
