Neutrophil Superoxide

Chronic granulomatous disease (CGD) is an inherited disorder of host defense against microbial infections caused by defective activity of the phagocyte NADPH oxidase. Based on an increase of neutrophil superoxide-generating ability in response to interferon γ (IFN-γ) in a single patient with CGD, multicentered group studies demonstrated a beneficial effect of prophylactic IFN-γ. However, no apparent increase of the phagocyte superoxide generation was found in patients enrolled in these studies. The present report offers an additional kindred in whom an IFN-γ–dependent increase in neutrophil superoxide production was observed in 3 affected patients. The defect in the CYBB gene for gp91-phox was identified as an otherwise silent mutation adjacent to the third intron of theCYBB gene that alters messenger RNA splicing. By molecular analysis, significant differences were found in the splicing pattern ofCYBB gene transcripts in patient neutrophils between 1 and 25 days after administration of IFN-γ. Furthermore, a complete transcript containing the missing exons could be detected in all specimens after the treatment. The changes in the splicing pattern of the transcripts and the prolonged effect on superoxide-generating ability of patient neutrophils indicate that IFN-γ induced a partial correction of the abnormal splicing of CYBB gene transcripts in myeloid progenitor cells.

Immunodeficiency Syndrome

Chronic granulomatous disease (CGD) is a rare inherited immunodeficiency syndrome that results from abnormal nicotinamide adenine dinucleotide phosphate (NADPH) oxidase function. This defect leads to recurrent catalase-positive bacterial and fungal infections as well as associated granuloma formation. We review the case of a 2-year-old boy who presented with ascites and fever of an unknown origin as manifestations of CGD. Cultures were negative for infection throughout his course, and CGD was suspected after identification of granulomas on peritoneal biopsy. Genetic testing revealed a novel mutation in the CYBB gene underlying his condition. This paper highlights the importance of considering CGD in the differential diagnosis of fever of unknown origin and ascites in children.

Abstract X-linked chronic granulomatous disease (CGD) derives from defects in the CYBB gene, which encodes the gp91-phox component of NADPH oxidase. We studied the molecular basis of the disease in a kindred with variant CGD, due to a single base substitution at the sixth position of CYBB first intron. The patients' phagocytes have been shown previously to greatly increase superoxide release in response to interferon-gamma (IFN-γ) in vitro and in vivo. We examined CYBB gene expression in an Epstein-Barr virus (EBV)-transformed B-cell line from 1 patient in this kindred. These cells showed markedly decreased levels of CYBB transcripts in total RNA (5% of normal) and nuclear RNA (1.4% of normal), despite equal CYBB transcription rates in the CGD and control cells. Incubation with IFN-γ produced a 3-fold increase in CYBBtotal messenger RNA (mRNA) levels in the patient's cells, and decreased nuclear transcripts to undetectable levels. Reverse transcriptase–polymerase chain reaction analysis of RNA splicing revealed a preponderance of unspliced CYBB transcripts in the patient's nuclear RNA. In vitro incubation with IFN-γ increased by 40% the ratio of spliced relative to unspliced CYBB mRNA in nuclei from the CGD B-cell line. Total RNA harvested from the same patient's monocytes, on and off therapy with IFN-γ, showed a similar improvement in splicing. We conclude that IFN-γ partially corrects a nuclear processing defect due to the intronic mutation in theCYBB gene in this kindred, most likely by augmentation of nuclear export of normal transcripts, and improvement in the fidelity of splicing at the first intron.

Variable Presentation

Chronic granulomatous disease (CGD) is a primary immunodeficiency disorder marked by abnormal phagocytic function. CGD affects primarily neutrophils and manifests as an early predisposition to severe life-threatening infections. Additionally, patients with CGD are predisposed to unique autoimmune manifestations. While generally spared from infectious complications, heterozygous carriers of the abnormal genes implicated in CGD pathogenesis can still present with autoimmune disorders. A mutation in the CYBB gene is the only X-linked variant of this disease. This article describes a family with the CYBB mutation, its heterogenous presentation, and reviews the literature discussing disease management.
