The 8q24 cancer risk variant rs6983267 shows long-range interaction with MYC in colorectal cancer

Abstract

An inherited variant on chromosome 8q24, rs6983267, is significantly associated with cancer pathogenesis. We present evidence that the region harboring this variant is a transcriptional enhancer, that the alleles of rs6983267 differentially bind transcription factor 7-like 2 (TCF7L2) and that the risk region physically interacts with the MYC proto-oncogene. These data provide strong support for a biological mechanism underlying this non-protein-coding risk variant. © 2009 Nature America, Inc. All rights reserved.
