ADD1 and gastric cancer: Wang, et al. performed a case-control study with 1998 cases and 2008 controls and found that ADD1-rs4963 (MAF = 0.496) might be associated with susceptibility to non-cardia gastric cancer (CG versus CC: OR = 1.24, 95% CI = 1.06–1.46, P = 0.008; GG versus CC: OR = 1.49, 95% CI = 1.25–1.78, P < 0.001) [25].
