PNAS takes action regarding breach of NIH embargo policy on a PNAS paper

PNAS takes action regarding breach of NIH embargo policy on a PNAS paper. PNAS published online before print September 18, 2009, doi:10.1073/pnas.0910317106

After the paper titled ‘‘PKNOX2 gene is significantly associated with substance dependence in European-origin women,’’ by Xiang Chen, Kelly Cho, Burton H. Singer, and Heping Zhang, published online August 31, 2009 in PNAS, our editors became aware that Dr. Zhang had signed a Data Use Certification indicating his agreement to comply with the NIH Genome-Wide Association Studies Policy for Data Sharing, which applies to the Gene Environment Association (GENEVA) studies, of which the Study of Addiction, Genetics and Envi- ronment (SAGE) is a part. Under the policy, investigators agree not to submit findings of the SAGE dataset(s) for publication until September 23, 2009. The PNAS publication clearly violates the SAGE embargo, and the authors agreed to retract their work in PNAS on September 9, 2009.
