The clinical history of six of the patients has previously been described in detail[19-22]. Genomic DNA was isolated from whole blood collected in EDTA with the Wizard Genomic DNA isolation kit from Promega (Nacka, Sweden). Custom synthesized primers were ordered from Invitrogen (Taastrup, Denmark). The 5′-fluorescently labelled oligonucleotides

were ordered from Applied Biosystems (Stockholm, Sweden). The Gene Scan selleck chemical analysis was performed as previously described [20, 23]. The ratio of functional genes to pseudogenes was determined by calculating the peak areas corresponding to the two fragments differing by only 2 bp. The five genes encoding the components of the NADPH oxidase complex were analysed in a sequential pattern with amplification and sequencing methods previously described [20, 24]. The molecular background of the Danish patients diagnosed with CGD and followed in the clinic was investigated, this cohort includes 27 patients. Sixteen of 27 patients (59%) had autosomal recessive mutations located in Org 27569 either NCF1 or CYBA. No mutations were observed in NCF2 or NCF4. Eleven patients had an X-linked mutation of the CYBB gene (Table 1). The present ages of the patients range from 14 to 60 years. Three

different mutations were found in a group of six patients. Patients 3, 4, 5 and 6 are related and harbour the same missense mutation p.Ala124Val in exon 6 of CYBA. Patients 1 and 2 are unrelated and both have a mutation in the 5′ splice site in intron 4, leading to the deletion of exon 4 in the mRNA transcript (Fig. 1). The deletion of exon 4 does not change the reading frame. At present, both patients are without symptoms even though their DHR test is negative. Patient 2 is only heterozygous for the splice site mutation but harbours a deletion of exon 6 on the other allele. In accordance with this finding, carrier status for the splice site mutation was only detected in the mother (Fig. 1). Ten different mutations were detected in the 11 patients with X-linked CGD. Patients 8 and 9 are brothers and have the same missense mutation p.Pro56Leu.
