Five male patients from four different families presented with a clinical record of chronic granulomatous disease (CGD): recurrent infections of the skin and/or respiratory tract with catalase-positive microorganisms, sometimes in combination with granulomata and/or abscesses in various organs. These patients differed from "classical" forms of the disease in that their neutrophils, although deficient in killing in vitro of Staphylococcus aureus, contained a decreased but measurable amount of cytochrome b558 (10-60% of normal on a heme basis), causing weak staining in the nitroblue tetrazolium dye test and a depressed respiratory burst after contact of the cells with fluid or particulate activators of the NADPH:O2 oxidoreductase. In the cell-free activation system, the defect in the patients' cells was localized in the membrane fraction. In each of the four families, the cellular abnormalities showed an X-linked inheritance. Fusion experiments performed with the monocytes from these patients and those from patients with classical X-linked, cytochrome b558-negative (Xb(0)) or autosomal, cytochrome b558-positive (Ab+) CGD showed complementation of NADPH:O2 oxidoreductase activity in the latter but not in the former combination. Thus, the unusual CGD patients represent variant forms of Xb(0) CGD, with mutations in the gene coding for the beta subunit of cytochrome b558 that do not cause complete loss of this protein.
