Abstract/OtherAbstract:
We cloned and characterized a genomic DNA fragment including the deletion junction of a chronic granulomatous disease patient with a 25-kb deletion extending to the 5' two-thirds of CYBB. The 3' breakpoint of the deletion exists in exon 7 of CYBB. A LINE-1 element lies at 5 kb upstream of CYBB in normal persons, and the 5' breakpoint of the deletion in the patient is in the LINE-1 element. There are no significant homologies between corresponding normal 5' and 3' regions flanking the breakpoint of the patient, so a nonhomologous recombination is the most possible mechanism for this 25-kb deletion. The analysis also reveals that the patient has a novel 30-bp duplication in the 5' flanking region of the deletion point, which was transmitted by his mother with the deletion. Furthermore we suggest that the deletion occurred in his grandfather.
