Abstract
We identified a set of SNPs in the first intron of the FTO (fat mass and obesity associated) gene on chromosome 16q12.2 that is consistently strongly associated with early-onset and severe obesity in both adults and children of European ancestry with an experiment-wise P value of 1.67 × 10−26 in 2,900 affected individuals and 5,100 controls. The at-risk haplotype yields a proportion of attributable risk of 22% for common obesity. We conclude that FTO contributes to human obesity and hence may be a target for subsequent functional analyses.

In the version of this article initially published, the authors failed to acknowledge that recruitment of obese cases was supported by both Assistance-Publique Hôpitaux de Paris and Centre National de la Recherche Scientifique. This error has been corrected in the PDF version of the article.
