Moreover, numerous genes are being reported for the first time and some of these genes are candidate oncogenes: Fgf3, Nmyc, Fap, Myct1, Gucy1a3, Gulp1 and Fkbp9 specific to megakaryoblastic leukaemias and Ssx2ip, Rab11a, Ncoa3, Snca, Ltbp2, Rabgef1 and Btbd14a specific to erythroleukaemias. This evidence concerns the gene RABGEF1 and leukemia.
