Distribution of genetic alterations in Ph-like and remaining BCP-ALL. (A) Panel A shows the distribution of common mutations, deletions and fusions and CRLF2 expression in Ph-like and remaining BCP-ALL (Ph-negative, MLL-t negative, non-Ph-like) patients. The definition of kinase and B-cell pathway reported by Roberts et al.5 was used. Patients represented by light gray boxes for Relapse and Death were not treated in GMALL trials 06/99 and 07/03 and no clinical data were available for them. Patients marked with “*” had either ETV6-RUNX1 or TCF3-PBX1 fusions or ALL with high hyperdiploidy. (B) Panel B shows the correlation of common mutations, deletions and fusions and CRLF2 expression in Ph-like and remaining BCP-ALL (Ph-negative, MLL-t negative, non-Ph-like).
