ATAC-seq of a selected group of AML cases
ATAC-seq data were generated for a number of selected patients to investigate changes in enhancer and promoter regions. ATAC-seq was essentially carried out as described in31. Briefly, prior to transposition the viability of the cells was assessed and 1 × 106 cells were treated in culture medium with DNase I (Sigma) at a final concentration of 200 U ml−1 for 30 minutes at 37 °C. After Dnase I treatment, cells were washed twice with ice-cold PBS, and cell viability and the corresponding cell count were assessed. 5 × 104 cells were aliquoted into a new tube and spun down at 500 × g for 5 minutes at 4 °C, before the supernatant was discarded completely. The cell pellet was resuspended in 50 µl of ATAC-RSB buffer (10 mM Tris-HCl pH 7.4, 10 mM NaCl, 3 mM MgCl2) containing 0.1% NP-40, 0.1% Tween-20, and 1% Digitonin (Promega), and was incubated on ice for 3 minutes to lyse the cells. Lysis was washed out with 1 ml of ATAC-RSB buffer containing 0.1% Tween-20. Nuclei were pelleted at 500 × g for 10 minutes at 4 °C. The supernatant was discarded carefully and the cell pellet was resuspended in 50 µl of transposition mixture (25 µl 2× tagment DNA buffer, 2.5 µl transposase (100 nM final; Illumina), 16.5 µl PBS, 0.5 µl 1% digitonin, 0.5 µl 10% Tween-20, 5 µl H2O) by pipetting up and down six times. The reaction was incubated at 37 °C for 30 minutes with mixing before the DNA was purified using the Monarch PCR & DNA Cleanup Kit (NEB) according to the manufacturer’s instructions. Purified DNA was eluted in 20 µl elution buffer (EB) and 10 µl purified sample was objected to a ten-cycle PCR amplification using Nextera i7- and i5-index primers (Illumina). Purification and size selection of the amplified DNA were carried out with Agencourt AMPure XP beads. For purification the ratio of sample to beads was set to 1:1.8, whereas for size selection the ratio was set to 1:0.55. Purified samples were eluted in 15 µl of EB. Quality and concentration of the generated ATAC libraries were analyzed using the High Sensitivity D1000 ScreenTape Kit (Agilent) and libraries were sequenced paired-end on a NovaSeq (Illumina). ATAC-seq reads were aligned to the human reference genome build hg19 with bowtie2

Data access policy of the EMC-HEMA-AML consortium for adult acute myeloid leukemia data
THE EMC-HEMA-AML CONSORTIUM DATA ACCESS AGREEMENT This agreement governs the terms on which access will be granted to the genotype data generated by the EMC-HEMA-AML (part of the ERASMUSMC-HEMA consortium) consortium. In signing this agreement, You are agreeing to be bound by the terms and conditions of access set out in this agreement. For the sake of clarity, the terms of access set out in this agreement apply both to the User and the User’s Institution (as defined below). User Institution and User are referred to within the agreement as “You” and “Your” shall be construed accordingly. Definitions: Consortium means the EMC-HEMA-AML Consortium comprised out of the following members: Dr. Bas Wouters, Dr. Ruud Delwel, Roger Mulet-Lázaro, Dr. Mathijs A. Sanders, Dr. Peter J.M. Valk, Data means all and any human genetic data obtained from the Consortium. Data Subject means a person, who has been informed of the purpose for which the Data is held and has given his/her informed consent thereto. User means a researcher whose User Institution has previously completed this Data Access Agreement and has received acknowledgement of its acceptance. Publications means, without limitation, articles published in print journals, electronic journals, reviews, books, posters and other written and verbal presentations of research. User Institution means the organization at which the User is employed, affiliated or enrolled. Acute Myeloid Leukemia is hereafter referred to within the agreement as "AML". Terms and Conditions: In signing this Agreement: 1. You agree to use the Data only for the advancement of medical research, according to the consent obtained from sample donors. 2. You agree not to use the data from the adult ALL cohort or any part thereof for the creation of products for sale or for any commercial purpose. 3. You agree to preserve, at all times, the confidentiality of information and Data pertaining to Data Subjects. In particular, You undertake not to use, or attempt to use the Data to compromise or otherwise infringe the confidentiality of information on Data Subjects and their right to privacy. 4. You agree not to attempt to link the data provided under this agreement to other information or archive data available for the data sets provided, even if access to that data has been formally granted to you, or it is freely available without restriction, without specific permission being sought from the relevant access committees. 5. You agree not to transfer or disclose the Data, in whole or part, or any identifiable material derived from the Data, to others, except as necessary for data/safety monitoring or programme management. Should You wish to share the Data with a collaborator outwith the same Institution, the third party must make a separate application for access to the Data. 6. You agree to use the data for the approved purpose and project described in your application; use of the data for a new purpose or project will require a new application and approval. The relevant access committess will see to it that the Data is not used in publications outside the project described in the original application. 7. You accept that Data will be reissued from time to time, with suitable versioning. If the reissue is at the request of sample donors and/or other ethical scrutiny, You will destroy earlier versions of the Data. 8. You agree to abide by the terms outlined in the Consortium 'Publications Policy' as set out in Schedule 1. 9. You agree to acknowledge in any work based in whole or part on the Data, the published paper from which the Data derives, the version of the data, and the role of the Consortium and the relevant primary collectors and their funders.

This agreement shall be construed, interpreted and governed by the laws of the Netherlands and shall be subject to the non-exclusive jurisdiction of the Dutch courts. SCHEDULE 1 Publications Policy The primary purpose of the EMC-HEMA-AML Consortium is to accelerate efforts to identify genome sequence variants influencing major causes of human morbidity and mortality, through implementation and analysis of large-scale genome-wide association studies. Additional objectives include the development and validation of informatics and analytical solutions appropriate to the scale and nature of the project, as well as use of the data generated to answer important methodological and biological questions relevant to association studies in general, and in the Netherlands in particular. The Consortium anticipates that data generated from the project will be used by others, such as required for developing new analytical methods, in understanding patterns of polymorphism and in guiding selection of markers to map genes involved in specific diseases. Authors who use data from the project must acknowledge the EMC-HEMA-AML using the following wording "This study makes use of data generated by the EMC-HEMA-AML Consortium. Cite the relevant primary EMC-HEMA-AML publication”. Users should note that the Consortium bears no responsibility for the further analysis or interpretation of these data, over and above that published by the Consortium.
Studies are experimental investigations of a particular phenomenon, e.g., case-control studies on a particular trait or cancer research projects reporting matching cancer normal genomes from patients.
