A Case of Primary Ciliary Dyskinesia due to Radial Spokes Deficiency
|
|
|
|

Abstract
|
|
|
|
Primary ciliary dyskinesia encompasses a heterogenous group of inherited condition characterized by clinical, functional, and ultrastructural features. The transmission electronmicroscopic findings of nasal cilia in a 14-year old girl with primary ciliary dyskinesia were studied. The ultrastructure of axonemes showed normal outer membrane, dynein arms, microtubules, and nexin links but partial lack of radial spokes. The nature of the defective spoke is not clear and further studies will be necessary to determine how the radial spokes and central sheath interact and coordinate ciliary movement.
