IL23R and neoplasm: The SNP rs6682925 locates at 907-bp upstream from the transcriptional start position of IL-23R. The web-based tool of TFSEARCH 1.3 (http://www.cbrc.jp/research/db/TFSEARCH.html) [12] showed that the T-to-G base change of rs6682925 might affect a predicted GATA-X transcription factor binding, which may be involved in tumor differentiation and other carcinogenesis-related pathways [30], [31].
