Supplementary Information Supplementary Figure 1. Chromatin signature profiling by mass spectrometry. 115 cell lines from the CCLE collection were subjected to chromatin signature profiling by mass spectrometry. Each row corresponds to a histone H3 peptide with the specific combination of marks shown on the right. The value in each cell of the heatmap corresponds to the log2-fold change of the mark combination vs. the median for each row. Tissue origin, hematological subtypes and mutation status of EZH2 and NSD2 are indicated. Clusters A-F are marked for reference in the main text.
Supplementary Figure 2. Cell lines containing NSD2 E1099K mutation express both wild type and E1099K mutant NSD2 alleles. cdna from six NSD2 E1099K mutant expressing cell lines and three NSD2 wildtype cell lines was subjected to Sanger Sequencing and sequencing chromatograms are shown; left and right columns are chromatograms using forward and reverse sequencing primers respectively. cdna sequencing of all mutant cell lines showed that both the wild type and mutant NSD2 transcripts are expressed. Mutation caused nucleotide change of Gà A (red) at codon 1099 (underlined and marked by red arrow in the chromatograms) resulting amino acid change of Eà K.
Supplementary Figure 3. Structural model of NSD2 E1099K mutation Structural model of NSD2 sequence mutations, E1099 (magenta stick with black text) to K1099 (white stick with red text) and D1125 (magenta stick with black text) to N1125 (white stick with red text). They are predicted to alter binding between NSD2 (green cartoon) and the histone peptide (blue cartoon). Amino acids K1124 and C1183 are labeled and shown as green sticks. Residues that line the I-SET histone binding groove are labeled with grey text and shown as green sticks (C1102, I1106, M1119, I1127, and T1121). The residues S31 (blue stick) and K36 (blue stick) are shown to identify modeled locations of residues on the H3 peptide. Black dash highlights key interactions.

Supplementary Figure 5. NSD2 variants identified in primary ALL samples promote H3K36 dimethylation and transformation. A) Western blot of KMS11-TKO cells reconstituted with NSD2-wt, NSD2-CDM (catalytic dead mutation), NSD2-E1099K, NSD2-E1099K-CDM (harboring both E1099K and the catalytic inactive mutation), NSD2-D1125N, NSD2-MB4-2 (N-terminal truncation), or the empty vector. NSD2 MB4-2 is a structural variant identified in pediatric tumor sample (see Supplementary information, NSD2 structural variations in pediatric cancer. Cell lysates were blotted with the indicated antibodies. Histone H3 serves as loading control. B) Quantification of soft agar transformation (in presence of 5% serum) of KMS11-TKO cells reconstituted with the indicated NSD2 variants. Error bars indicate the s.d. of triplicate samples. C) Quantification of soft agar transformation of KMS11-TKO cells reconstituted with the indicated NSD2 variants in the presence of 10% serum. Two independent experiments were shown. Error bars indicate the s.d. of triplicate samples. This set of experiments was performed to evaluate if different serum concentration (5% vs 10%) might affect the outcome of soft agar transformation. The actual number of colonies differs under the different serum concentration. Overall, these data showed transforming activity of (NSD2 E1099K ~ NSD2 D1125N ~ MB4-2) > NSD2 wt > (vector control ~ NSD2 CDM ~ NSD2 E1099KCDM).

Supplementary Figure 8. An example of NSD2 mutant isoform detected by RNA-seq in the three ETV6-RUNX1 ALL cases with intra-genic 5 deletion. A) Junction reads from RNA-seq across the alternative exon 1 and exon 6 confirm a novel isoform resulting from intra-genic genomic deletion in sample ETV086. The junction reads spans the alternative exon 1 (encoded only by isoform 10 of NSD2, accession NM_001042424) and exon 6 of NSD2. The alternative ATG is shown in black box. B) Mutant protein with truncated N-termini predicted from the mutant transcript.
Supplementary Figure 9. An example of inter-chromosomal re-arrangement resulting in fusion of the 5 UTR of ST6GAL1 with exon 1 of NSD2 Junction reads in RNA-seq that span 5 UTR of ST6GAL1 (left box, in blue) and the first coding exon of NSD2 (right box, in black) resulting from inter-chromosomal translocation in sample LGG039. The junction reads mapped to ST6GAL1 were marked as the soft-clipped reads by bwa (shown in light blue color in Bambino viewer at the left).
