We found no significant differences in expression of both markers between the adult controls and the patients with PCD (CD16 expression (mean ± SEM) on neutrophils of PCD relative to Ad CO: 114.0 ± 9.8%, p = 0.1968; CD11b expression (mean ± SEM) on neutrophils of PCD relative to Ad CO: 152.4 ± 25.3%, p = 0.3890). The gene discussed is ITGAM; the disease is primary ciliary dyskinesia.
