MMP7 and gastric cancer: We further observed a significant association of the variant genotype; gastric cancer patients carrying GG of MMP-7 (-181A/G; rs11568818) had a greater increased risk of MMP-7 expression than did wild-type (WT) carriers (AG: odds ratio (OR) = 5.67; 95%CI = 1.57–7.23; p = 0.024 and GG: OR = 8.32; 95%CI = 2.94–11.42; p = 0.016).
