  1. Previously primary tumor is indicated between brackets
  2. mERRBS was performed on all samples except on CTL 5, t-MN 3 and t-MN 5; RNA-sequencing (RNA-seq) analysis was performed on all samples except on CTL 1, due to quality control
  3. M male, F female, mERRBS multiplex enhanced reduced representation bisulfite sequencing, DIC dic(1;7), CTL control, t-MN therapy-related myeloid neoplasm, t-MDS therapy-related myelodysplastic syndrome, AML acute myeloid leukemia, ET essential thrombocythemia, JAK2+ Val617Phe detected at diagnosis of ET, NHL non-Hodgkin lymphoma, NA not available due to quality control
  4. aMutations: mutational results indicate whole exome sequencing (WES) for DIC cohort and denaturing high-performance liquid chromatography (DHPLC)/Sanger screening of MDS-related genes for CTL and t-MN cohorts (detailed gene list and results are reported in Supplementary Table 1)
