Moreover, MMP-7 rs11568818 in Asians under the recessive model was related to bladder cancer risk, while MMP-9 rs3918242 was relevant to BC risk among the Asian populations in the allelic model and to oral cancer risk among the overall populations in the allelic model with oral cancer); it was weak for MMP-2 rs243865 among the Asian populations with LC risk in the recessive model, among the overall populations with LC risk in the dominant model, and among the Asian population with NPC risk in the dominant model. The gene discussed is MMP7; the disease is urinary bladder cancer.
