Abstract

Chronic granulomatous disease (CGD) is a rare inherited disorder of the innate immune system caused by a defect in NADPH oxidase, leaving the granulocytes unable to kill invading microorganisms. CGD is caused by mutation in one of the five components gp91phox, p22phox, p47phox, p67phox and p40phox, encoded by the X-linked CYBB gene and the autosomal CYBA, NCF1, NCF2 and NCF4 genes respectively. We have collected samples from all Danish patients with known CGD followed in the clinic or newly diagnosed during a 5-year period, a cohort of 27 patients, and characterized them genetically. The cohort includes 10 male patients with X-linked CGD and one female with extremely lyonized expression of a defective CYBB allele. Six patients had mutation in CYBA. Seven of 10 patients with a defect in NCF1 were homozygous for the common GT deletion, one was compound heterozygous for the GT deletion and a splice-site mutation, and two patients were homozygous for a nonsense mutation in exon 7. Three novel mutations were detected, a deletion of exon 6 in CYBA, a duplication of exon 8-13 in CYBB and a splice site mutation in intron 7 of NCF1.
