Six genes CCSER2, AGAP11, IFIT2, PAPSS2, PCGF5, and NUDT9P1 were observed to have potential NB tumor suppressor activity since their low expression was associated with poor survival even after correction for confounding by other prognostic factors (MYCN status, age at diagnosis, stage of disease). The gene discussed is PCGF5; the disease is neoplasm.
