Maciejewski is Chair of the Department of Translational Hematology and Oncology Research at Cleveland Clinic Taussig Cancer Institute. He is a leukaemia geneticist known for defining the mutational landscape of myelodysplastic syndromes, discovering somatic mutations in MDS and aplastic anaemia including in splicing factors and TET2. His selected paper reports somatic mutations and clonal haematopoiesis in aplastic anaemia. He now studies clonal evolution in bone marrow failure and its progression towards acute myeloid leukaemia.","asOf":"2026-09-08","links":[{"label":"Cleveland Clinic profile","url":"https://www.lerner.ccf.org/thor/maciejewski/"},{"label":"PubMed","url":"https://pubmed.ncbi.nlm.nih.gov/?term=Maciejewski%20JP%5BAuthor%5D"}],"tags":[],"related":[],"cancers":["aml"],"sections":[],"technologies":[],"targets":[],"drugs":[],"companies":[],"institutions":["cleveland-clinic"],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"role":"Chair, Department of Translational Hematology and Oncology Research","institutionId":"cleveland-clinic","specialisms":["Myelodysplastic syndromes","Bone marrow failure","Clonal haematopoiesis"],"profiles":[{"label":"Cleveland Clinic profile","url":"https://www.lerner.ccf.org/thor/maciejewski/"},{"label":"PubMed","url":"https://pubmed.ncbi.nlm.nih.gov/?term=Maciejewski%20JP%5BAuthor%5D"}],"papers":[{"title":"Somatic mutations and clonal hematopoiesis in aplastic anemia","journal":"New England Journal of Medicine","year":2015,"url":"https://doi.org/10.1056/NEJMoa1414799","doi":"10.1056/NEJMoa1414799"}],"orcid":"0000-0002-6837-4346"},"route":"/people/jaroslaw-maciejewski/","neighbours":{"cancer":[{"id":"aml","kind":"cancer","name":"Acute myeloid leukaemia","route":"/cancers/aml/"}],"institution":[{"id":"cleveland-clinic","kind":"institution","name":"Cleveland Clinic Taussig Cancer Institute","route":"/institutions/cleveland-clinic/"}]}}
