Answer

Patients with Young syndrome have bronchiectasis (often predominant in the lower lobes), sinusitis, and obstructive azoospermia. However, they do not display the other findings of CF. The pathogenesis of bronchiectasis in these patients is believed to be similar to that of bronchiectasis in CF. The criterion standard for diagnosis of Young syndrome is electron microscopic analysis of the structure of the cilia.
