We found that SNRPD3, SNRPF and LSM4 had the strongest independent prognostic effect on neuroblastoma patient outcome among the core spliceosome assembly genes as measured by hazard ratios for event-free (EFS) and overall (OS) patient survival (Fig. 1D and Supplementary Fig. 1A). Here, SNRPD3 is linked to neuroblastoma.
