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.
These syndromes, caused by inherited mutations, include xeroderma pigmentosum (XP), Bloom syndrome, Rothmund-Thomson syndrome, Werner syndrome, Muir-Torre syndrome, multiple self-healing squamous epitheliomata (Ferguson-Smith syndrome), dystrophic epidermolysis bullosa, junctional epidermolysis bullosa, epidermodysplasia verruciformis, Fanconi anemia, dyskeratosis congenita (Zinsser-Cole-Engman syndrome) and certain albinism syndromes.
