TAS2R38 and colorectal cancer: In contrast to this study, in a case–control study on Caucasians [41], a higher risk for colorectal cancer (OR—1.34; 95% CI—(1.12, 1.61); p = 0.001) was found for non-tasters by comparing all the diplotypes of TAS2R38 linked to non-tasting phenotypes, with the diplotypes eliciting tasting phenotypes.
