ARID1A and chronic myelogenous leukemia, BCR-ABL1 positive: In other myeloid malignancies, mutations in SWI/SNF genes seem to be extremely rare (< 1%), and, if present, they mostly affect ARID1A. This is the case for AML [51], CML [203], and myeloproliferative neoplasms such as juvenile myelomonocytic leukemia [204, 205], chronic myelomonocytic leukemia [206], chronic neutrophilic leukemia [207], chronic eosinophilic leukemia [208], and others [112, 209–213].
