Common genetic variants of candidate genes such as TCF7L2 (transcription factor 7 like 2), PPARG (encoding peroxisome proliferator-activated receptor γ), HNF1B (encoding hepatocyte nuclear factor 1 homeobox B), JAZF1 (encoding JAZF zinc finger 1), KLF14 (encoding Kruppel-like factor 14) were reported to be associated with different cancer types including cancer of oral cavity, breast, colon, pancreatic, liver, prostate and many more [16]. The gene discussed is KLF14; the disease is cancer.
