In 11q23.3, rs75438046 maps to the 3′ UTR of CXCR5, which controls viral infection in B cell follicles [79], and BCL9L, a translocation target in acute lymphoblastic leukemia [80] and transcriptional activator of the Wnt/β-catenin cancer signaling pathway [81]. This evidence concerns the gene BCL9L and cancer.
