A GWAS study identified 21 new loci, three of them were located within 150 kb of integrin gene (ITGA4, ITGAV, and ITGB8) cluster, and one overlapped with a fourth integrin gene, ITGAL. Integrins are bidirectional signaling cell adhesion mediators that play an essential role in leukocyte homing and cell differentiation in inflammation and cancer. Here, ITGAV is linked to cancer.
