In the article “Strong Evidence for a Novel Schizophrenia Risk Locus on Chromosome 1p31.1 in Homogeneous Pedigrees From Tamil Nadu, India” by Elizabeth G. Holliday, Ph.D., et al. (published online October 1, 2008), the following information should have been included in the article information section just before the references: “Elizabeth G. Holliday, Ph.D. and Dale R. Nyholt, Ph.D., contributed equally to this study.” This change has been made for the article’s appearance in the February print issue and for its online posting as part of that issue, replacing the article posted October 1, 2008.
