The authors would like to apologize for an omission in the above paper. The following text should be added to the Acknowledgements: ‘We thank Andreas Fiebig and Stefan Schreiber at POPGEN (University of Kiel, D-24105 Kiel, Germany) for providing control samples’.

In addition, on page 4049, the authors mistakenly described a copy number variant as a ‘loss’ instead of a ‘gain’. The sentence should read: One 22q11.2DS subject with schizophrenia had a 1.48 Mb gain at 15q13.2-15q13.3 (chr 15:28,748,100 … 30,231,500) that was inherited from an unaffected parent.
