No gender predilection is recognised. C ] – Absent or abnormal dynein arms of sperm and respiratory epithelial cilia by electron microscopy [UMLS: In situ hybridization studies indicated that the transgene was transcribed during meiosis, as early as the primary spermatocyte stage, whereas the appearance of human EGF receptors was delayed until the post-meiotic stages of sperm differentiation.
All show identical defects by electron microscopy, namely defects in the central microtubular structures Pennarun et al. One of the 6 affected individuals had dextrocardia; all had sinopulmonary symptoms with abnormalities of the cilia by electron microscopy.

In vitro studies have shown that various patterns of abnormal ciliary beating Rossman et al. It probably results from elevated levels of local inflammatory mediators in a chronically irritated airway.

The segregation ratio in the progeny of 2 carriers would then be not one-fourth but one-eighth. Sturgess et al [ 6 ] described how the radial spoke, which serves to translate outer microtubular sliding into cilial bending, was absent in some patients with primary ciliary dyskinesia.
Prenatal Diagnosis Wessels et al.
