Re: “The Influence of Screening For Precancerous Lesions on Family-Based Genetic Association Tests: An Example of Colorectal Polyps and Cancer”

The funding and principal investigator information in the article “The Influence of Screening for Precancerous Lesions on Family-Based Genetic Association Tests: An Example of Colorectal Polyps and Cancer” by Schmit et al. (1) was incorrect. The revised version of this information is below. This work was supported by the National Cancer Institute (grants U19 CA148107, R01 CA52862, UM1 CA167551, R01 CA112237) and the National Institute of Environmental Health Sciences (grant T32 ES013678). This work was also funded through cooperative agreements with the following Colon Cancer Family Registry centers: the Australasian Colorectal Cancer Family Registry (grants U01 CA074778 and U01/U24CA097735); theMayoClinicCooperativeFamilyRegistry for Colon Cancer Studies (grant U01/U24CA074800); the Ontario Familial Colorectal Cancer Registry (grant U01/U24 CA074783); the Seattle Colorectal Cancer Family Registry (grant U01/U24 CA074794); the University of Hawaii Colorectal Cancer Family Registry (grant U01/U24 CA074806); and the University of Southern California Consortium Colorectal Cancer Family Registry (grant U01/U24 CA074799). Principal investigators of the Colon Cancer Family Registry sites include Dr. Robert W. Haile, Dr. Dennis J. Ahnen, Kristen Anton, Dr. GrahamCasey, Dr. Iona Cheng, Dr. James M. Church, Dr. Timothy Church, Dr. Steven Gallinger, Dr. Mark A. Jenkins, Dr. Loic Le Marchand, Dr. Noralane M. Lindor, and Dr. Polly A. Newcomb. The authors regret these errors.
