The rs2234235 in TAS2R1 was linked to confirmed/probable infection in individuals with respiratory disease (OR: 2.65; CI: 1.08, 5.61; p = 0.018) or IMID (OR: 7.39; 95% CI: 1.36, 33.8; p = 0.012), as well as in those without diabetes (OR: 2.08; CI: 1.11, 3.57; p = 0.013). This evidence concerns the gene TAS2R1 and diabetes mellitus.
