In the disease association analysis (neoplasms, cancer or viral infections, breast neoplasms, neuroblastoma), the LMO3, MYB and BIRC3 oncogenes were also significantly upregulated whereas the WISP2, IGFBP5 and RASSF2 tumour suppressor genes were significantly downregulated in FFs compared to NFs. This evidence concerns the gene CCN5 and neoplasm.
