We also identified nominal associations of genetically predicted circulating levels of macrophage inflammatory protein-1β (MIP1β) with the risk of AML (OR=0.86, 95% CI: 0.75-0.99, P=0.048), colon cancer (OR=0.95, 95% CI: 0.90-0.99, P=0.015) and rectal cancer (OR=0.89, 95% CI: 0.84-0.94, P=2.75×10-5), as well as eotaxin with the risk of colon cancer (OR=1.28, 95% CI: 1.09-1.49, P=0.003), multiple myeloma (OR=1.58, 95% CI: 1.08-2.29, P=0.017), and stomach cancer (OR=1.68, 95% CI: 1.16-2.44, P=0.006). This evidence concerns the gene CCL4 and malignant colon neoplasm.
