- Abstract
One of the rarest forms of chronic granulomatous disease (CGD) is caused by mutations in CYBA, which encodes the p22-phox subunit of the phagocyte NADPH oxidase, leading to defective intracellular killing. This study investigated eight patients (six males and two females) from seven consanguineous, unrelated families with clinical CGD, positive family history and p22-phox deficiency. Mutation analysis of CYBA showed six different novel mutations: deletion of exons 3, 4 and 5; a missense mutation in exon 6 (c.373G>A); a splice site mutation in intron 5 (c.369+1G>A); a frameshift in exon 6 (c.385delGAGC); a frameshift in exon 3 (c.174delG); and a frameshift in exon 4 (c.223delC).
