On page 5368 of the 9 December 2010 issue, the affiliation of the second author (Fisher) is incomplete. He is correctly assigned to the WIMM in Oxford but not to the particular unit in which he worked within the Institute, which is the MRC Molecular Haematology Unit. The correct affiliation for Dr Fisher should have been: MRC Molecular Haematology Unit, Weatherall Institute of Molecular Medicine, John Radcliffe Hospital, Headington, Oxford, United Kingdom, and the corrected affiliation list is shown. The error has been corrected in the online version, which now differs from the print version.
