Therefore, starting with the stomach, a case–control study in a Korean population [37] showed an increased gastric cancer risk (OR—1.513; 95% CI—(1.148, 1.994); p = 0.001) associated with the PAV/AVI diplotype of TAS2R38, which evokes an intermediate bitter taste sensitivity to PROP and PTC. The gene discussed is TAS2R38; the disease is gastric cancer.
