Experimental Protocol

The ALL genomes of four patients (Patients P1-P4) were sequenced in bone marrow samples collected at diagnosis, to an average 20-30-fold sequence depth per base. Patient 1 has the recurrent B-cell precursor ALL (BCP-ALL) translocation t(12;21)ETV6-RUNX1, Patient 2 has BCP-ALL with two non-recurrent translocations, Patient 3 has BCP-ALL with a normal karyotype, and Patient 4 has T-cell immunophenotype ALL (T-ALL). The four ALL genomes were compared to pools of B-cells (n=7) and T-cells (n=17) from healthy blood donors and a CD34+ reference (GSM791828). We also interrogated potential effects of epigenetics on gene expression using RNA-sequencing data from three of the ALL samples (P1, P2, and P4) and B- and T-cells. 450k BeadArray data GSM1203860, GSM1203904, GSM1204111 and GSM1203962 corresponding to P1-4 was used for validation. ---------------------------------------- Submitter declares reads will be made available through dbGaP/EGA
