The authors report that the abstract contains an error. The fifth sentence should have appeared as follows: Sixteen patients from 14 unrelated families had X-linked CGD (66.7 %), four had mutations in the NCF1 gene (19 %), and three, from two unrelated families, had mutations in NCF2 (9.5 %). The error does not affect the integrity of the data or study conclusions. The authors regret the error.
