NFYA and neuroblastoma: NF-YAx cDNA was cloned from a stage 3 NB and sequence characterised as a novel NF-YA splice variant with in-frame exons B, D and partial F sequence skipping, adding to existing NF-YAl, NF-YAs and NF-YA L2–6 variants [8, 12, 13, 17], with potential implications for NB pathogenesis and progression.
