Genes in NK cells (i.e., BCL11B for T-ALL, MAP3K7IP2 for prostate cancer) and in monocytes (i.e., LCK and BCL11B for T-ALL, PDCD1LG2 for Hodgkin’s lymphoma, PRDM16 for AML, CACNA1D for prostate cancer) were found significant in our meta-EWAS. This evidence concerns the gene CACNA1D and acute lymphoblastic leukemia.
