BARD1 and neuroblastoma: As so far, five neuroblastoma GWASs have been performed, and several neuroblastoma susceptibility genes have been identified such as CASC15/CASC1414, LMO115, HACE1 and lin‐28 homolog B (LIN28B) 16, BARD1 limited to high‐risk neuroblastoma 17, as well as three low‐risk neuroblastoma susceptibility genes (DUSP12 at 1q23.3, DDX4 and IL31RA both at 5q11.2, and HSD17B12 at 11p11.2) 18.
