Four lncRNAs (FIRRE, LINC00839, EPB41L4A‐DT, and CASC15) have also previously been identified to be prognostic of survival in NB patients by the study conducted by Sahu et al,22 which focus on identifying lncRNAs differentially expressed in different MYCN amplification group and different risk group. The gene discussed is CASC15; the disease is neuroblastoma.
