RB1 and acute lymphoblastic leukemia: An average Ph+ ALL disease network model was computed following the same principles: From Mullighan et al., we extracted the 11 potential deletions to compute initial probabilities proportional to deletion frequencies (IKZF1, 84%; CDKN2A, 53%; PAX5, 51%; C20orf94, 23%; RB1, 19%; MEF2C, 14%; EBF1, 14%; BTG1, 14%; DLEU, 9%; FHIT, 9%; ETV6, 7%), with non-deleted genes having 0 probability [17].
