DDX4 and neuroblastoma: Common variants within the FLJ22536, BARD1 and LMO1 genes are significantly associated with susceptibility to high-risk NB, whereas SNPs within DUSP12, DDX4 and IL31RA are associated with less aggressive NB (Maris et al, 2008; Capasso et al, 2009; Diskin et al, 2009; Nguyen le et al, 2011; Wang et al, 2011).
