In the article by Callén et al entitled “A common founder mutation in FANCA underlies the world's highest prevalence of Fanconi anemia in Gypsy families from Spain,” which appeared in the March 1, 2005, issue of Blood (Volume 105:1946-1949), there is a mistake in the first sentence of the second paragraph of “Results and discussion.” The Afro-American FA patients of Ghana origin have a truncating mutation in exon 4 of FANCC, not in FANCA.

Therefore, the phenotypic effects of this mutation cannot be compared with the Spanish Gypsy truncating mutation in exon 4 of FANCA.
