Erratum for vol. 101, p. 2089

In the article by Sadler entitled “Von Willebrand disease type 1: a diagnosis in search of a disease,” which appeared in the March 15, 2003, issue of Blood (Volume 101:2089-2093), the sentence in “Acknowledgments” should have read “I thank Professors Anne Goodeve, David Lillicrap, Ian Peake, and Francesco Rodeghiero for helpful comments and for sharing unpublished information about ongoing studies of VWD type 1.”
