AUTOSOMAL RECESSIVE CHRONIC GRANULOMATOUS-DISEASE ASSOCIATED WITH 18Q- SYNDROME AND END-STAGE RENAL-FAILURE DUE TO HENOCH-SCHONLEIN NEPHRITIS

Chronic granulomatous disease (CGD) is an inherited disorder in which phagocytes, including polymorphonuclear neutrophils, are unable to generate oxygen-derived microbicidal compounds, among them superoxide [1]. Two main types of CGD are known, an X-linked form which is normally associated with the absence of cytochrome b558, a component of the membrane-associated reduced nicotinamide adenine dinucleotide phosphate (NADPH) oxidase which generates superoxide and an autosomal recessive form, in which cytochrome b558 is present, caused by the deficiency of a cytosolic factor required to activate NADPH oxidase [4]. Patients with the X-linked type are highly susceptible to infections; those with the autosomal recessive form may be less severely affected [10]. We report the unusual association of autosomal CGD with 18q- syndrome in a girl who developed terminal renal insufficiency caused by Henoch-Schonlein nephritis, and speculate on the possibility that the gene defect of autosomal recessive CGD may be located on chromosome 18.
